Icarus
Lich King Icarus is invisibly bound to Hardin's Academy by Hardin himself. Since he is undead he doesn't require food, or sleep. He states that humans taste "stringy" anyway. He is the sole survivor of the 13 Lich Kings who once shook the Elmoreden Empire to its core. His magic and knowledge of necromancy are unrivaled by anyone, anywhere. Now he spends his time at the Academy devoting himself to his students and sharing his knowledge. In his former life, before he became dead resp. undead, he was a Human mystic, so now he mainly teaches Human students magical skills.
