Zargash

Zargash is a Human who originally hailed from the world of Mystara. As a Cleric of Orcus, he makes a fearsome addition to the League of Malevolence, but he chafes at being less in rank than the Sorcerer Kelek. He would likely make an attempt to seize control, but he greatly fears Kelek's bodyguard, Warduke. For now, he bides his time and looks for an opportunity.
Zargash was present in the Palace of Heart's Desire when the Hourglass Coven imprisoned the Arch-Fey Zybilna. He and Kelek were seeking to further their ends when the Witchlight Court interfered, eventually freeing members of Valor's Call and defeating Zargash and his fellows. Now he is being taken back to Mystara to face justice.
