Sch'theraqpasstt (pronounced schikthere-AUK-past) was once a lesser god that ruled the 111th plane of the Abyss, and from there orchestrated the creation of the yuan-ti ages ago. However, he was not satisfied with being "simply" a god, and he devised a method to gain ultimate power.
Sch'theraqpasstt attempted to merge his life-essence with the plane he ruled and become, in effect, a living dimension. His scheme destroyed him by giving him what he wanted. He succeeded in merging with his plane of the Abyss, but no intellect, no matter how powerful, could stand the strain of being joined with pure Chaos. All but a minute portion of his psyche went insane; with what little of his mind was left, he formed the body described herein, a shadow of his former self.
This manifestation appears as a 60'-long, winged, ebony serpent. The attack modes are bite and, constriction. Those bitten take 2-12 hp damage and must save versus poison at -4 or contract a form of insanity. Such insanity can be cured with a heal, wish, limited wish or alter reality spell. Constriction causes 3-30 hp damage, and such damage is automatic every round after the first hit. Sch'theraqpasstt can constrict up to six small-size, four mansize or two large-size creatures per round.
A +2 or better weapon is needed to hit Sch'theraqpasstt, and in addition to his magic resistance, he is immune to all mind-affecting spells (including illusions). All beings within 100' of Sch'theraqpasstt must save at the beginning of every round or be affected as per a scarab of insanity.
Sch'theraqpasstt flits through the multiverse in a random fashion, rarely staying in one place for more than one turn. He has been seen on the Prime Material plane several times and will always be there on the Night of Venom, usually where the greatest number of yuan-ti are singing his praises. At this time he will be somewhat rational, but at other times there is a 10% chance per round that his intelligence will slip from supragenius to complete idiocy. If Sch'theraqpasstt goes insane during a battle, he fights to the death, with + 2 on all to-hit, damage, and saving rolls, and a -2 penalty to his opponents' saves vs. his poison and magical effects.
If Sch'theraqpasstt's material form is killed, his psyche returns to his home plane of the Abyss and reforms over a period of 111 days. The only way to truly destroy this being is to destroy his entire plane. Thus, at the price of his godhood and sanity, Sch'theraqpasstt attained an indestructible immortality.
This being's home plane is known as "The Mind of Evil." The only activity there is the chaotic whirling of an intelligent, insane plane. Anyone transported here is at the mercy of Sch'theraqpasstt and, as magic does not work here, has almost no chance of survival. Note that all planar travelers are aware of this peril and avoid that layer of the Abyss at all costs.
Part of the yuan-ti plan after conquering the world is to gather all the magic they can find and use it to reverse the downfall of their god. Whether this can be achieved is unknown, but there are few persons outside yuan-ti society who wish to see this come about.
