Editing Darklord (section)

==Illithid God-Brain==
The darklord of Bluetspur is an [[illithid]] [[Elder Brain]], a massive conglomeration of the brain of every dead illithid, merged together into a new, living, entirely alien entity. It's the reason using psionic powers in Ravenloft is a dicey proposition, as the God-Brain might notice and attempt to integrate you into itself. It's notable for having '''no''' attempt to justify its position in Ravenloft whatsoever, with the original writeup in the Red Box, the original Ravenloft campaign setting collection, literally saying that nobody knows why it's in the [[Demiplane of Dread]], what crime it committed to end up here, or even how it's actually being tormented by its stay here!

The ''Book of Sacrifices'' gives it a backstory and reason for its Darklordship. Its core persona was once a human psion named Seldrid, whose people were at war with the Illithids. Eventually, they began to win for good once the Illithid Elder Brain started to die, but unfortunately for them, Seldrid had come to admire the Illithids' power and discipline, and merged with the Elder Brain to revive it. This act of betraying his people to such a great evil caught the Dark Powers' attention, and as the Illithids sacked his home city, they drew the country into the Demiplane of Dread as Bluetspur, with the Seldrid-brain as Darklord. Seldrid's curse is an inability to transfer his consciousness as he once did or to integrate any new consciousnesses into himself. Now trapped as a giant brain in a pool with nothing but Illithid tadpoles for company, unable to make himself more mobile or gain any outside experiences, Seldrid has gone quite insane.

===5e===
5th edition has its own take on the idea. In a nutshell, the God-Brain hails from the era when the Illithid empire was at its peak, performing whatever blasphemous experiments took its fancy until it literally thought something that was unthinkable. That is, it had a thought so blasphemous, so utterly inimical to reality itself, that even an Elder Brain couldn't actually think it. Becoming obsessed with this ineffable thought, the God-Brain began cannibalizing other Elder Brains to try and upgrade itself to the point where it could finally contemplate this mysterious thought-form. Instead, it just gave itself kuru. Aghast at its behavior and terrified of catching the disease themselves, the other Elder Brains pooled their powers and tried to erase the God-Brain from existence; thanks to the meddling of the [[Dark Powers]], they only succeeded in banishing the God-Brain to the [[Demiplane of Dread]]. Now the God-Brain struggles endlessly to both find a cure for its disease and to manifest the alien thought-form still gestating inside of it, all the while subconsciously aware that there is '''nothing''' it can do to achieve either goal, but desperate to fight for every last moment of life.

In 5th edition at least, the God-Brain cannot fully close the borders like other Darklords do.  When the borders are closed, the surface of Bluetspur becomes covered in lightning storms and anybody who isn't an aberration that exits the domain both by above or below ground suddenly wakes ups in a familiar place with no memories of their time in Bluetspur.
