Monster page: skills, variants and drops

A candidate for Arch Daeva born after the Last War and leader of the Lepharists in Elysea. He rose to his current position by helping with Dragon Lord Ishtar's Sura research, seeming to be minion of the Balaur, but was actually cultivating his own power. He is arrogant because of his genius, and has rejected Asahr's revelations as enslavement by AION. His ultimate goal is to become a god greater than the Balaur, Daeva, and even AION.
