Located in the Concordant Domain of the Outlands is one of the most infamous and justly feared Cosmic Entities in the history of the Mortal Coil: Ilsensine. Some individuals do not think that it exists, as it’s machinations at this point are often incredibly subtle, compared to the legends of it’s enormous power that are the only commonality between the triad of mutual racial loathing composed of the Illithids, the Githyanki, and the Githzerai. However, it is very real, and aspects of it’s history may be pieced together through various sources, including such texts as the Sargonne Prophecies.

History

In the far future, or rather, one version of it, the Gith shall prove victorious not only over each other and the Illithids, but over all other mortal races. A triumphant Gith empire came to reign over not only The Mortal Coil, but the Void Between.

Yet despite their incredible power, there were some events that they could not forestall. Among them was the End; not just of themselves, but of everything. Certain scholars among them once claimed that their to preserve their own world at the expense of the timeline actually hastened this End, and brought it closer to coming to pass. The unfortunate among them were caught and slain; the more devious of these dissidents managed to hide among the myriad Realms under Gith control.

Despite these warnings, the Gith experimented with means of preventing their End, first by ascertaining exactly how it would come to pass, and then by attempting to develop means of actually stopping it. Their first discovery was that they would die from an undescribed horror. This discovery actually encouraged their continued experimentation.

Finally, four extremely powerful Chronomancers from this temporally distant empire experimented with magics that were far beyond even their own capabilities in order to attempt to save themselves. Their plan for evading the annihilation of all things were to open a portal into a plane they had discovered that was made of pure mental energy. In this manner, they could preserve themselves, and eventually find another plane where they could develop new bodies are restore themselves.

However, time itself would not be frustrated so easily.

The portal opened, but in the process, it simoultaneously allowed the Void Beyond entry to The Mortal Coil. In that brief instant, they became the horror that they were attempting to evade, causing not only the End that they were attempting to avoid, but simoultaneously projecting themselves far backwards in time. Their bodies, as well as most of their original memories of their previous lives, were destroyed by the backlash of their attempted escape, yet their brains continued to live. Fused together, they interlinked and were animated by the bizarre mental energies of the portion of the Void Beyond that they attempted to use in order to bypass the normal constraints of magic.

In a past so distant that the Depths Below were one, flat, plane of despair, this alient sentience re-emerged in Creation. Simoultaneously with this act, The Circle of Three was sundered and the Overlord’s plummet created the Nine Hells of Perdition. Even as this act of definition occured, so too was the entity from the Void Beyond fully realized in itself. Although still bound in part within the Void, this sundering was of sufficient power to allow this Law-tainted madness creative power.

This earliest thought; of Lawful Evil and a desire to control all things, interacted with the four Chronomancers even as their accident, only taking a second of unsurpassable agony according to their own time scale, hurtled them back to the beginnings of creation itself. They fused into the being that would call itself Ilsensine, even as it settled on a long-forgotten realm in The Mortal Coil, and planned best how to make creatures that would be it’s preferred tools for domination.

There were still limitations on it’s enormous power, however. Most species proved incompatible with the bizarre energies that gave it life to the point where it was only after thought-lifetimes of experimentation that they realized that a smaller being, the first worm-like pieces of brain tissue used in Ceremorphosis, could succeed in creating lesser vessels in order to accomplish it’s ends. Although phenomenally intelligent, it had little choice but to accept a few, select species as compatible with Ceremorphosis until much later, ‘mutating’ them into the first Illithids.

While obtaining physical bodies with which to channel the massive psionic energies of Ilsensine, the results, the first Illithids also had their share of weaknesses. They were intolerant of sunlight and more sensitive to desiccation than their modern descendants; inspiring as a common goal for many of them to extinguish the suns of their worlds, or banish natural lights. The larval tadpoles that were initially engineered also proved to be far more prone to mutation than originally expected, causing the psionic worms known as Neothelids and Psurlons to be formed if they actually managed to escape domination and control through implantation into suitable humanoids, or bizarre and psionically-competent lifeforms sharing some aspects of Ilsensine’s parasitic life cycle.

One year later the entire world fell to Ilsensine’s power. This long-forgotten world became the seat of the Illithid Hegemony, and an even more horrific fate befell the last demigod remaining on this long-forgotten world as Ilsensine itself Ceremorphosized it; turning it into the Eldest Brain. The Eldest Brain, in turn, used astral travel to reach other realms in The Mortal Coil, creating lesser images of itself, and the cycle of conquests and domination began.

For thousands of years, the Illithid Hegemony expanded. There are few records of this time period by the standards of those within either the Mortal Coil or the Outer Planes. In the case of the former it was a period of hideous thralldom that most of the deities that would come later agreed to attempt to expunge, whether because of the concern amongst the good-aligned deities that it was too traumatic, or in the case of the evil gods, inspired by jealousy at Ilsensine’s capabilities for evil and domination. Eventually, it managed to subjugate a species that, unusual throughout the Mortal Coil, proved to be capable as warriors and simoultaneously unusually sensitive to the psionic energies that the Illithid Elder-Brains used to control the various worlds under their sway. This species was known as the Gith.

The rapid ascension of Ilsensine and the Illithid Hegemony under it’s control could hardly help but come to the attention of Perdition, as at the height of their empire, not only did they control most of the realms in The Mortal Coil and damage some of the Upper Planes, but they came to directly affect the Blood War and started seeking alliances among other entities of both Law and Evil. At the height of the Illithid Hegemony's power, it is said that even Demon Lords and Princes even chose to aid Ilsensine in it's campaign of domination against all lesser beings.

It is unknown which Lord of the Nine aside from Asmodeus first became aware of the Illithid’s rapid expansionism, although it is postulated to have either been Mammon, who noticed the loss of souls and wealth from myriad Prime Material Planes as they were removed from his ability to collect them for his own purposes, Dispater through his own psionic might, or Mephistopheles. Regardless of who precisely learned of Ilsensine first, it presented a serious problem to Asmodeus as Asmodeus ascertained that Ilsensine was one of the few beings, besides the controlled Adremalech, that was aware of the true nature of the King of Hell.

Tiamat, as a newly promoted Lord of the Nine, wished to increase her power by creating a stable worshipper base for herself outside of the armies of chromatic dragons she had at her beck and call already. As a result, she decided to use her incredible level of control over dragons in order to provide aid to the resistance against the Illithid Hegemony, and simoultaneously turn the Gith thralls of Ilsensine into a race of permanent servants to her, spread across the Mortal Coil and powerful enough to give her a significant advantage in competing against much older and more senior Lords of Hell in their own campaigns to bring ordered evil to all of creation.

The keystone of her plan, ironically, was the one action that seemed the most singularly implausible to be supported by the forces of tyranny-namely a slave revolt. There had always been escapees from the Illithid Hegemony but by this particular point in time there were three particular figures of note among them. They were Gith, the de facto leader of the revolutionaries by virtue of surviving the longest in fighting Ilsensine and it’s minions, Zerthimon, recognized as the philosophical leader among them, and Vlaakith, the first powerful Sorcerer that their kind had ever produced in independence.

Tiamat, through her Red consort at the time, Ephelemon, promised the aid of Red Dragons to the revolt through Vlaakith. In exchange, Vlaakith would betray both Gith and Zerthimon after the initial campaign against Ilsensine was successful, in the process becoming the sole leader of the entire Gith civilization and committing them on a course of promoting permanent, unending tyranny while campaigning to exterminate the Illithids until there were none left anywhere.

The day the revolution started, the plan succeeded wonderfully even while it failed horribly. On hundreds of Planes, nearly simoultaneously, dozens of Red Dragons descended upon their worlds through portals and gates and incinerated Illithid cities even while the Gith revolted en masse against their oppressors for tens of centuries. Elder Brains died by the thousands, and many of the Eldest Brains were killed by Gith, Zerthimon, and Vlaakith accompanied by their personal bands of warriors.

Unknown to anyone, however, was that Zerthimon had been compromised by Ilsensine in advance of the beginning of the revolt. Realizing that nothing it could do would stop the plans that had already been laid in well in advance by Vlaakith and her backers in the Hells, it opted instead to use Zerthimon as a distraction once the revolution started in order to buy time for a counteroffensive.

After the initial wave of successes against Ilsensine, Zerthimon issued what was known as the Declaration of Two Winds, which laid the groundwork for the split between the githzerai and the githyanki.

The result was, in effect, a splintering among all of the different forces involved. The Gith divided between the followers of Vlaakith and Zerthimon, failing to utterly destroy the Illithids but successfully liberating themselves. Ilsensine survived, but the power of the Illithid Hegemony was forever broken and from those days onwards, would never even be a pale shadow of it’s once-mighty power. Tiamat failed to destroy the entirety of Illithidom and they failed to co-opt the entirety of the Gith into their service.

The split between the followers of Vlaakith, who named themselves Githyanki, and the followers of Zerthimon, naming themselves Githzerai, quickly turned into a situation where, as more of the Gith realized that neither major faction of their leaders was really interested in their freedom, groups of them rejected both the misdeeds of Zerthimon as well as Gith himself-giving rise to the current fractured state of the Gith people, with some of them following Vlaakith, some of them following the teachings of Zerth, and a significant portion of them just not caring about much else except for personal development and, of course, slaughtering Illithids. Gith herself was lost among the internecine warfare, and the blame that each faction placed upon the other only furthered the division.

For Ilsensine and the Illithid Hegemony, however, the Gith revolt was only the beginning of their troubles. Their demonic and yugoloth allies rapidly turned against them, sensing an opportunity to gain as much control over the Mortal Coil as possible in the turmoil. As a result of it’s defeats, Ilsensine went to hide in the one place where the sensing powers of Vlaakith’s faction of the Gith could not follow: somewhere within 500 miles of the Great Spire in the Outlands. Using it’s immense psionic power, it quickly carved out a labyrinth underground, transmuting the bodies of most of the remaining Eldest Brains into extra cerebral tissue, and their vesicular fluids into a nutrient pool that would, with regular resupplies from sacrificed and manipulated creatures, provide it with enough power points to fuel it’s healing.

There it still remains, rebuilding it’s strength over the course of millenia, and using various ceremorphed creatures as spies to acquire the power it needs to restore it’s empire.

Ilsensine’s Cosmic Realm is the Caverns of Thought, a sprawling underground labyrinth located 500 miles from the base of the Spire in the Concordant Domain of the Outlands. While the greatest physical danger offered by the Caverns is touching one of the neuron-walls while Ilsensine is thinking, doing 6d6 points of electrical damage to oneself in the process, the dangers to mind and soul are far greater. In order to keep it’s hemispheres thinking in a manner that is eminently logical and appropriate for a being of it’s stature, Ilsensine excretes it’s own emotional wastes in the form of a truly enormous amount of psionic static. Each round that a sentient being is within the Caverns of Thought, it must make a Will save DC 35 just to be able to manifest any psionic powers at all. If a sentient being remains in the Caverns of Thought for a day or longer, it must make a Will save DC 25 each day it remains or else take 1d6 Intelligence and Wisdom damage from having Ilsensine’s powerlust, emotional fragments from the Void Beyond, and undying hatred for the Gith pounded into their brains relentlessly every single second that they remain; with a 1 on a failed save, one point of the ability damage because ability drain. This saving throw DC additionally increases by 5 per day that a sentient being remains in the Caverns of Thought. Should a being be brought to either 0 Intelligence or 0 Wisdom, they collapse on the ground wherever they are, permanently rendered catatonic. Mind blank can protect sentient beings from Ilsensine’s psychic static, but it must be cast or manifested at 60th level or higher, and should a being attempt to make the save in the physical presence of Ilsensine the difficulties are much greater, forcing them to make the save at a –9 penalty each round.

Goals

Although the execution of Ilsensine’s goals is so complex that they would take years to explain to lesser minds (and even then, much of their subtlety would be lost), those same goals may also be summarized in a single sentence: Life must be Dominated. To accomplish this end, Ilsensine subtly interacts with the lesser Elder Brains that have been formed since the end of the Illithid Hegemony, and those exceptionally rare Eldest Brains that survived the war and the accompanying slaughter of most of them. Although a subject of much debate among the members of the various Illithid Creeds; in fact, Ilsensine monitors all of them covertly in order to discover additional information that may aid it in it’s quest to restore the empire that it once possessed.

Illithids are some of the most intensely detested beings across the Mortal Coil and the Outer Planes, and they have few allies anywhere, much less their creator. With rare exceptions, beings are either a thralls to them or food (and the two are nearly synonymous in the Illithid telepathic-tongue, for that matter), much less to their creator.

Relations with other deities

Ilsensine is more or less everybody’s problem.

The guardians of Temporalis Procellos are well aware of the origins of Ilsensine, although none of them, even Merorem the Darkwind, are aware of it's relationship with the Overlord. Unfortunately, there is little that they can actually do in order to prevent Ilsensine from bringing itself into existence because all of the options for eliminating Ilsensine in that manner actually damage history more than leaving him in it; it has touched upon too many other planes, too many other events of import, and is considered stubbornly anchored in the timeline as a result. This, however, does not stop them from fighting against Ilsensine and the efforts of it’s servitor Illithids to expand it’s already hideous reach across the cosmos, as if they can destroy Ilsensine after it has created itself, all of their calculations indicate that it will never come back from a death in that manner.

The forces of good are universally opposed to Ilsensine, in particular the Defenders of Freedom, which see it’s boundless appetite for intelligent minds as well as it’s contentions that thralldom is the only aspiration worthy of non-Illithids as complete and total anathema to their own ideals. One of the most agonizing arguments that goes on among them is whether to make temporary alliances with the myriad other beings, such as the Drow, which are also staunch opponents of the machinations of Ilsensine and it’s sinister offspring, but at the same time are not good themselves and have little interest in it.

Among the Demiurge and their servants, their reactions to Ilsensine are no less vehement, although far less intellectual in nature most of the time. Lolth utterly despises Ilsensine, and her Drow and demonic minions have many among their number that have learned secrets and tricks of Illithid-slaying from the descendants of Gith that they have either captured and tortured, or in the case of the more depraved members of Ilsensine’s former servants, have actually allied with because their hatred of Ilsensine is so vast. Ilsensine often has the equivalent of neuronal spasms, the equivalent of nightmares for a psionic creature such as itself, when considering the random and horrific power of Demogorgon, and it is quite likely that all manner of Demiurge and Demon Princes would ally specifically against the Prince of Demons rather than risk it gaining access to the ancient knowledge and power of Ilsensine...should Demogorgon ever discover the Caverns of Thought.

Most evil deities are equally adamant in their hatred for Ilsensine as their good compatriots. Ilsensine bears special hatred for the daughter of Laduguer, Deep Duerra, who used experimentation and torture upon Illithids in order to wrench from them the secrets of psionics and give to her own worshippers. Even more insolent to Ilsensine were the actions of the derro Archlich/deity Diirinka and his brother, Diinkarazan, who used an artifact to steal knowledge from Ilsensine and grant it to their own brethren, although at the incredibly high cost of the sanity of every single derro within the Mortal Coil, and Diinkarazan’s permanent imprisonment and derangement within The Abyss.

One of the few exceptions to the mutual loathing that Ilsensine has for all other beings of power is The Gas Giant and sole surviving direct offspring of The Great Mother, Gzemnid. Gzemnid’s Realm intertwines, and is allowed to intertwine with the Caverns of Thought, forming in some directions an outer, protective zone which is guarded by the Beholder Entity and it’s servitors. One common speculation is that Ilsensine wished to improve it’s defenses after the incident with Diirinka; which Gzemnid and his hordes of Beholders do more than adequately.

The relations between Ilsensine and the forces of Perdition are quite convoluted at this point as well. Despite Ilsensine’s well-merited antipathy for Perdition and it’s innumerable servants, Ilsensine allows the cooperation of certain Illithids with the Hells; this is because this provides for the possibility of information gathering against the Hells if those Illithids return to their own communities and are incorporated into Elder Brains that Ilsensine may, in turn, co-opt for it’s own purposes. Although Ilsensine would consider the concept of ‘revenge’ to be grossly illogical, it still desires the diminution of Hell’s power as a threat to reclaiming it’s own and is extremely ruthless, even by it’s own standards, in the pursuit of any information that may help it towards it’s end. As with most things concerning Ilsensine, most of his actions are quite subtle in nature, as it’s previous defeat has taught it caution.

Description

Ilsensine is a spherical, pink brain ten feet wide with four constantly waving, 10-foot long tentacles that glow with a bright, yet sickeningly green light that is but a pale reflection of the psionic power that flows through them. Typically Ilsensine lies submerged in it’s nutrient pool, a dark blue mass of viscous liquid which allows it to withdraw power points as if it was a power crystal. It will only emerge partially out of it’s pool when angered by the approach of someone else.

Spell-like abilities (Sp): At will: astral projection, blasphemy, brain spider, calm emotions, charm monster, charm person, command, comprehend languages, create undead, desecrate, detect thoughts, dictum, discern lies, dispel chaos, dispel good, enthrall, good hope, greater command, hold monster, insanity, levitate, suggestion (mass), telepathic bond (lesser), telepathic bond, magic circle against chaos, magic circle against good, order’s wrath, plane shift, probe thoughts, protection from good, protection from chaos, quest, suggestion, unholy blight. 6/day: demand, dominate monster, mind blank, monstrous thrall, shield of law, summon monster IX (lawful and evil creatures only), true domination, unholy aura, weird. Cast at 65th level. Saving throws are 23 + spell level, except for Enchantments which have saving throw DC's of 24 + spell level. The saving throw DC’s are Charisma-based.

Blindsight (Ex): Although Ilsensine possesses no eyes or proper sensory organs in a conventional sense except for what it can touch with it's tentacles, it is fully capable of sensing it’s environment through tiny fluctuations of electricity produced through motion. As such, Ilsensine may be considered to have blindsight in a radius of 1800 ft. around it.

Mind Blast (Ex): This attack is a cone 100 feet long. Anyone caught in the cone must succeed at a Will save (DC 41) or be stunned for 21d4 rounds.

Call The Transformed (Sp): Ilsensine may call a total of 180 HD worth of Illithids or Illithid-related creatures (such as Neothelids or Ulitharids) in a single day, but no creature that it calls may have a higher CR than 35.

Cosmic Divinity (Ex): Although the illithids are not what most would consider to be ‘religious’, there are among the spellcasting members of their species those that have been selected by Ilsensine to serve a special purpose based on their superlative competence and intellects. To those individuals selected, they may be granted spells from the domains of Charm, Domination, Mind, Evil, Law.

Ilsensine possesses a virtual divine rank of 18 as defined in the “Virtual Divine Ranks and Cosmic Entities Defined” article regardless of location. It’s cosmic realm is known as Caverns of Thought in the Outlands, a sprawling labyrinth of caves made of brain tissue where it has lurked since the successful Gith revolution against it’s tyranny.

Cosmic Presence (Ex): The physical presence of Ilsensine is so powerful and awe-inspiring that it causes lesser creatures to succumb to its magnificence. All creatures within 1000 feet of Ilsensine must succeed in a Will save 55. Failure indicates the creature succumbs to an emotion of Ilsensine’s choosing. Ilsensine normally chooses to make those creatures that wander or are attracted to the Caverns of Thought so awestruck by it’s presence as to ease interrogation, or alternately, it will induce unreasoning terror in creatures which approach it’s caverns in beings that it does not wish to deal with in order to keep them away from it’s demensne.

Domain Powers: Ilsensine casts both Lawful and Evil spells at +1 caster level, gains a +2 bonus on Bluff, Diplomacy, and Sense Motive checks, a +2 bonus on Will saves against enchantment spells and effects, the Spell Focus (Enchantment) feat, and may gain +4 Charisma for 1 minute 1/day as a free action.

Patron Qualities (Ex): Ilsensine is immune to acid and electricity and possesses fire and cold resistance 20. It has DR 30/epic and silver and regeneration 14/silver and good. Ilsensine is immune to mind-affecting effects, polymorphing, petrification, or any other attack that alters its form. It is not subject to energy drain, ability drain, or ability damage. Ilsensine does not age, does not need to eat, sleep or breathe, is immortal, and cannot die from natural causes.

Additionally, Ilsensine may sense anything within one mile around the mention of it’s name, titles, or an item of importance to it for up to one hour after the event. This power is barred from places associated with beings with divine ranks or virtual divine ranks of higher than it.

Patron Omniscience: Ilsensine may sense any event that affects any of it’s children 18 weeks in the past and 18 weeks in the future. When Ilsensine senses an event, it merely knows that the event is occuring and where it is. It recieves no sensory information about the event.

Ceremorphosis (Ex): As a full round action with two of it’s tentacles, Ilsensine may implant pieces of itself in any living creature that has an intelligence score. It accomplishes this by taking two of it’s tentacles, inserting them into the auditory canals (or suitable orifices) of a living creature, and then transforming it’s brain tissue. They must make a Will save DC 61 or over the course of the next 18 rounds, Ilsensine will telepathically command the mutated brain that it has inserted into it’s target to literally redesign their body into what Ilsensine considers to be absolute perfection.

Humanoids transformed through this process will become Illithids utterly convinced of Ilsensine’s superiority to all other life, losing any class and alignment abilities that are incompatible with Ilsensine’s powers and alignment and adopting the subtypes Psionic, Lawful, and Evil instead. Any other creature transformed will take on the Ceremorph template but will still have their alignment automatically change to both Lawful and Evil if it was not such previously.

The changes that Ilsensine inflicts upon other beings are exceptionally difficult to reverse, requiring the aid of a deity possessing the Mass Life and Death Salient Divine Ability and an equivalent or greater divine or virtual divine rank than Ilsensine.

Even more nightmarish, however, is Ilsensine's limited capability to incorporate the divine through Ceremorphosis. Ilsensine may use Ceremorphosis against any deity with Divine Rank 5 or lower. Should the deity fail the Will save, they are transformed into an Elder Brain of equivalent hit die, and every single worshipper of the deity in question must make a similar Will save or else turn into an Illithid as well.

Ilsensine’s ability to engage in Ceremorphosis, however, is extremely limited and it may only do this 13/year although there are persistent rumors that in Ilsensine’s ‘youth’ as a power, it was able to convert far more individuals then that it is now. Usually such transformation is the culmination of a labyrinthine sequence of plans in order to help restore itself to it’s former position of glory in the Planes; the contingencies of which are so convoluted as to almost defy description.

Extract Mind (Ex): If Ilsensine begins a turn with two of its four tentacles attached and successfully maintains it’s hold, then it’s target must make a Will save DC 55. Should the target lack divine rank and they fail the save, then their mind and soul have been extracted from their bodies by Ilsensine’s psionic mastery leaving them a soulless, drooling husk. Ilsensine gains 1d10 temporary power and hit points for each HD of it’s target that it consumes and absorbs the sum total of all of their memories into it’s eldritch mass permanently. The victim loses 1d4 Con per round until they are dead. Temporary hit and power points gained in this manner are lost at the end of an hour.

As Ilsensine has been accumulating the memories of countless sentient beings for untold millenia, this has provided him with an additional benefit; Ilsensine receives a +10 insight bonus to any Intelligence-based check that he makes. This has been included in his statistics above.

Ilsensine may instead opt to use such an individual emptied by placing a selection of memories and sufficient knowledge into it’s body to allow it to continue living, but enthralled to Ilsensine; whether it chooses to do this or not is largely dependent on it’s needs at the time. Ilsensine may additionally choose to turn such a victim into either a Voidmind, or a Brain Golem.

Creatures drained in this manner may only be restored to life through the use of the Mass Life and Death Salient Divine Ability by a deity of equivalent or greater Divine or Virtual Divine Rank than Ilsensine, and even then, there is only a 50% chance that memories stolen by Ilsensine can be returned to a victim.

Psionic Mastery (Ex): Ilsensine is the most powerful psion in the Planes and few beings even marginally approach it’s mental prowess. Ilsensine may manifest any psionic power it wishes from any discipline or psionic class that is not incompatible with it’s alignment and manifests all powers at 65th level from a power point reserve of 993. It may also manifest 10 epic powers per day with a maximal Psicraft DC of 129. The saving throws against Ilsensine’s powers are DC 30 + power level + relevant augmentation. Ilsensine may also expend it’s psionic focus and manifest a power at 73rd level using the Feats Power Penetration and Greater Power Penetration. Ilsensine may affect any sentient living creature or outsider with it’s telepathic prowess, including beings with lower divine ranking than itself. Ten times a day, Ilsensine may instead choose to boost it’s manifester level or the saving throw of a power when manifesting a single power by it’s virtual divine ranking, giving it a manifester level of 83rd level for the purposes of that particular power and saving throws against it’s powers of 48 + power level + relevant augmentation. This boost also stacks with the feats Power Penetration and Greater Power Penetration, should it choose to use them.

Ilsensine is also the permanent beneficiary of a much more powerful variant of the Schism psionic power, allowing it to manifest four different powers simoultaneously at full level, or to use any of it’s four tentacles independent of the other three without penalty to the attack roll as if it had taken the Multiattack and Improved Multiattack feats. While this offers benefits in terms of combat (which Ilsensine naturally loathes), in other situations this has proved to be a hindrance as each of the quadrants of Ilsensine is likely to formulate it’s own plan of action and then telepathically argue it to the rest of Ilsensine.

Ilsensine may also devise new psionic powers to better serve it’s desire for universal conquest at an accelerated rate. Research for Ilsensine requires 20 XP per day and takes one day per level of the power. As a result, Ilsensine has been responsible for the development of hundreds, if not thousands, of novel psionic powers.

Ilsensine furthermore may incarnate any power that is not discharge-activated and has a time duration dependent on manifester level upon himself, even if such an incarnation falls far beyond the normal limitations of the psionic power. Ilsensine may have up to nine such special incarnations active upon itself at any given time, and may dismiss an incarnation as a full-round action.

Finally, 13 times a day, Ilsensine may enter a Planar Metaconcert with up to six different Illithids that it is aware of, anywhere simoultaneously. A Planar Metaconcert with any particular Illithid lasts for 13 rounds, and comes at a great price for those that contact has been initiated with. For each round that contact has been initiated, they must make a Will save DC 43 or else take 1 Wisdom damage as even by Illithid standards, the mind of Ilsensine is so unimaginably powerful that to contact it brings them pain.
