This is from my Blue Moon Empire project
Troll Heresy
The Blue Moon Trolls always had an important place for Annila, the Blue Moon Goddess, unlike most trolls. The formation of the Empire and the Goddess walking among them and providing a home for many trolls under the islands of her Moon, where the sun cannot touch them, has led the Blue Moon Trolls into full blown heresy.
Trolls initiated to her cult can live comfortably underwater, and the light of the Blue Moon during the day protects them from the Sun. (Conveniently, the Blue Moon sets when the Sun sets). They now see Annila as the supreme mother of Trollkind and Kygor Litor as her daughter, while Nysalor is seen as, basically, evil incarnate, too evil even to be eaten. And Trolls will eat Chaos creatures.
One of the central goals of the cult is to obliterate Nysalor; the deepest enemy of the cult are the Nysalorean Riddlers who show up like outbreaks of plague. According to cult tradition, Arkat tore off Nysalor's arms and legs, then forced him to eat his own genitals, then chopped his torso into four pieces, then cracked his skull open and ground his brains into powder. So there are ten pieces of Nysalor, though one piece is powder in a jar. Unfortunately, he hauled them all off to Stygia and when that fell, the pieces were scattered.
The cult has found five of the pieces and keeps them at hidden, widely separated locations - they have the skull, the upper right piece of the torso, the left arm (found by Sheng Seleris, recovered when he was slain), the brain powder, and the lower left piece of the torso. The case of Sheng Seleris revealed something horrible - a person missing the appropriate part can graft a chunk of Nysalor to their body and gain some of his power.
Someone bringing a chunk of Nysalor to the Blue Moon Trolls would be greatly rewarded.
Blue Moon Trolls are not immune to the curse on Trollkind, but those initiated to the Blue Moon only give birth to trollkin in one of three births instead of half the time. They believe they can end it entirely if they can ever get their hands on all of Nysalor's remains.
