Xirxes

Xirxes was the name of a necromancer who eventually became a powerful Lich after falling into the service of the Other Side.

History
Xirxes's early life is all but erased from history, barring that he was once a mortal necromancer who served the Other Side quite zealously during the reign of the Lux-Ferous Empire. He was an infamous murderer in his time, eventually arrested by the Lux-Ferous and executed.

Despite his death, Those on the Other Side had taken a liking to Xirxes, and rewarded him for his service to them by reviving him as a monstrous Lich. The Naga of the swamps saw him as a godlike figure, and helped him build the Lich's Tower deep in the Naga Homelands. The Emperor at the time, feeling responsible for Xirxes's rise to power, assaulted the Tower with his army and managed to bind the Lich to a Bloodstone seal. The Lich's vault, home to many powerful Other Side artifacts, was buried as the tower collapsed and Xirxes was forgotten.

Centuries later, a noob-ass necromancer named Slaq Bonebleacher would discover the ruins of the Lich's Tower and break the seal in an attempt to rob the artifacts within the Lich's vault, releasing him into the world once more.
