Selvetarm

Overview
Selvetarm, known also as The Spider that Waits or Lolth's Champion, is a chaotic evil demigod worshipped by few drow in the Underdark; the place where his worshippers are most common are in the city of Eryndlyn. He is the patron of unequaled battle prowess and bloodlust. Selvetarm cares only for battle and destruction everywhere, and he has a great hatred for all things living, although that is nothing compared to the hate he has stored for his mistress Lolth.

Worshipers
The Church of Selvetarm usually acts over the manifestation of soul spiders, and also common spiders. He manifests his pleasure by the discovery of stones, dried bark or webstone, and his anger by making pieces of weapon or armor break upon contact. All of the Selvertargtlin are trained in the sword in addition to the clerical skills. Although the church is mostly males, a handful of females worship Selvetarm.

Relationships
Selvetarm is grudgingly allied with Lolth, and Garagos due to the similarity of their personalities and portfolios. He fiercely opposes his father Vhaeraun's machinations.

History
Selvetarm was born from the brief union between Vhaeraun and Zandilar the Dancer, a demipower worshipped by elves in Yuirwood and later absorbed by Bast who would become Sharess, which was part of an elaborate plan to help Zandilar's followers against the attacks of Lolth's.

Selvetarm was alone for a time, until he was befriended by Eilistraee who showed him the ways of good, but all this would be shortlived as a result of the trickery of Lolth. The Spider Queen was enraged by the existence of a demonic lesser lord of the Abyss, who professed himself as having power over spiders, and whose name was Zanassu. Around this time the spider demon Zanassu had been weakened by a conflict in the Prime Material Plane, and so Lolth tricked Selvetarm into destroying the Abyssal lord and absorbing his divine power, under the false pretences of winning Eilistraee's gratitude. But in his actions Selvetarm also absorbed enough of Zanassu's malevolence to overcame his acquired goodness. Lolth used this to her advantage and entrapped Selvetarm's will, binding her grandson to her service
