If anybody is lurking, but struggling for an ideas, the first few that popped into my head are as follows:

Undeath, pestilence / decay, death, war, anger / hate, deceit, desire, gluttony, greed, terror, destruction, sorcery, knowledge, murder, betrayal, madness, slavery, darkness(?), nightmares, pain, torture.

Hope they can serve as some sort of inspiration for someone.
