the Jester
Legend
Hilariously, 3.0 brought into existence the "Good Lich", which I personally abhor. The Arch-Lich (Good, divine casters turned Lich), and the Baelnorn (elven liches) are both good aligned, but generally weaker than an actual Lich.
To quibble, good liches first arrived in 2e; the archlich was from Spelljammer and the baelnorn was a Forgotten Realms beastie.
