communicates telepathically in whispers, tempting the wielder with power, reminding them of the flaws of the gods. It demands to be fed divine blood weekly — failure to do so results in madness (short-term or long-term at DM's discretion). Its ultimate goal is to be driven into the heart of a god. “They abandoned you. I won't. Let me show you what lies behind the throne of the heavens.”
