Quest for the King
An evil demon the Yuan-Ti believe to offer great power.
Sertrous is an evil demon god wielding great power. He is Chaotic Evil and, like most demons, desires nothing less than chaos and destruction. He appears to be planning great destruction and will eventually devour the world.
Sertrous is forgotten by the races, and started to fade away until a band of Yuan-Ti discovered him. The Yuan-Ti revived the King’s bones with Sertrous’s spirit in it. Now the Guardians of Fallcrest needs to stop him from devouring the world.
