Kangaxx

Kangaxx was a powerful lich residing in Athkatla.

History
Kangaxx's enemies attacked and destroyed him, but were not aware of how to properly destroy a lich. Kangaxx later met the young Abdel Adrian and tricked him into recovering all parts of his body. However, when Abdel and his party delivered the past part, Kangaxx tried to kill them. After a fierce battle, Abdel emerged as the victor, destroying Kangazz for good.
