From the introduction: In a concerted effort to spread discord and evil among the mortal races, the god Set sired many bastard offspring via its dalliances among them. The result was a jumble of divine and mortal traits, but all of his children were hideous snake, reptilian, and humanoid crossbreeds. Each was a unique, twisted fiend, as Set steeped his creations in chaotic sorcery. These he called his sons, and they were spread far and wide to disseminate their vile plots.
