Legends of the Dreaming Sea
Bloody hands are gods of murder, their duty is to observe murders, not commit them. In their material form a bloody hand looks like a tall, thin human dressed in black with blood constantly dripping from its hands.
Many bloody hands have gone rogue after watching murders for so long, some collect trophies, other protect and encourage serial killers. People will sometimes approach a bloody hand for information on a killing, but the only payment they want for their information is another murder.
