Phantasms are malevolent and sinister spirits that delight in the destruction of good-aligned creatures. While many undead creatures are the undead form of once living creatures, phantasms have no real material connection to living creatures; they are spirits born of pure evil. They are most often found haunting ruined temples or churches dedicated to evil gods, or dungeons constructed by evil creatures; any place where the stench of evil permeates the very air.
