A lich is a powerful undead person, often a king or magician, with a rotting or skeletal body. A lich keeps their intelligence, unlike zombies, and they come from early fantasy fiction from the likes of H.P. Lovecraft. The word comes from a term used in the Catholic and Anglican churches, "lychgate," which is the place where the casket waits for the clergy member before going into the cemetery. "Lich" comes from the old English "lic," which means "body" or "corpse."
