Amarantha

Liches are highly intelligent, utterly insane by human standards, and almost universally evil. They are obsessed with the acquision of power and knowledge, and immortality grants the lich patience to see incredibly long-term plans come to fruition Liches typically care little to involve themselves in the day-to-day affairs of mortal realms, preferring to sequester themselves in hidden lairs to conduct arcane research or formulate epic plans. Most liches forget their original names over time, and are known to most only by cryptic aliases or titles A lich does not need to eat, sleep or breathe, but over its epic lifespan must eventually consume mortal souls to sustain the magic that protects its undead form. A lich who fails to maintain their body in this way degrades into a demilich, a form consisting of a single bone, usually a skull. Some liches intentionally accept this transformation in order to withdraw from the world. Liches commonly possess great collections of spellbooks, potions, scrolls, wands, staves, and other magic items.[1] They have lived long enough to acquire an exceptional amount of wealth, though they do not necessarily have any particular love of gold as dragons do. Liches have been known to develop unique magic items for themselves and their undead allies, many of which are useless in the hands of living adventurers.
