The babau is an assassin, a murderer, and a sadist-certainly not traits unusual in the demons, yet the babau's penchant for stealth and surprise sets it apart from its generally less-subtle kin. With no need to eat (although most babaus relish the flavor of mortal meat on their thin, raspy tongues), a babau can wait in ambush for years or decades-their inhuman patience in anticipating a well-conceived murder also setting them apart from the other denizens of the Abyss. Babaus obsess over the act of killing and take great pride in their grisly art, often leaving behind some form of grim marker or obscure signature, whether it be a distinctive modus operandi, an unnerving token, or other profane evidence.
