Drakel, the leader of The Lich's Eye
Lichdom is a status of immortality in the form of the undead. Many Necromancers and evil clerics have devoted their lives to attain lichdom to continue their evil causes. Even good Necromancers and Clerics have devoted their lives to Lichdom as a sacrifice to protect the planet and its inhabitants, often called ArchLiches, though they are often rare and many do not even know of their existence.
Unfortunately for those who choose unlife, their only weakness lies within their phylactery, whose own soul resides inside of, should it be destroyed, they too shall be destroyed.
