Zovaal, better known as the Jailer or the Banished One, was an Eternal One who ruled over the Maw in the Shadowlands. Ruling from the Sanctum of Domination in Torghast, Tower of the Damned, he wielded powerful Domination magic and was the singular and absolute master of the Maw: the realm continually altered and changed itself to his whims,and he observed all actions of note within his domain through his magical eye.The damned souls who arrived in the realm were tortured and twisted by the Jailer until they willingly served him for eternity as his Mawsworn soldiers.
