When the life force of a  lich  ceases to exist and the material body finally decays (often after centuries of undeath), the soul lingers in the area and slowly over time possesses all that remains of the  lich  \xe2\x80\x93 its skull. The eye sockets and teeth of a demi-lich-possessed skull transform into clear gemstones (each worth 1,000 gp). The skull contains a single gemstone in each eye socket and six gems in place of its teeth. \n'b' A demi-lich rarely if ever wanders from its place of origin (i.e., the final resting place of its body when it was a true  lich ). Content to remain hidden and oblivious to the outside world, a demi-lich spends its time contemplating its past life, its accomplishments, as yet unachieved goals, and exploring strange mysteries of the cosmos. These creatures are solitary by nature and rarely associate with other creatures, including other undead unless it is employing such creatures to further some unfinished goal. \n'b' Demi-lich lairs are usually well-hidden dungeons and caverns consisting of winding corridors, deadly pitfalls, and intricate traps (some that would even bring a tear to Grimmy\xe2\x80\x99s eye). \n'b' A demi-lich appears as a simple humanoid skull seated amid a pile of bones and dust. In each eye socket is a single gemstone, and in its mouth, in place of its teeth, are six more gemstones. \n'b' A demi-lich sits idly in its lair until touched or bothered at which point it rises vertically and uses its wail of the banshee power against the opponent it deems most threatening. On its next turn, the demi-lich uses its trap the soul ability against an opponent. It spends the remainder of combat alternating between its wail of the banshee,  bestow curse , and trap the soul abilities.'
