(Pain) Purgatory Mercenary Ogghorn

Lore
Ogghorn descends upon the battlefield astride his gargantuan dragon. He then immediately seeks to die. For only by throwing himself into battlefield where he may not emerge alive can Ogghorn release to full extent of the powers contained in his massive, steely frame. Even if he were surrounded by tens of thousands of enemies, his bloodlust would not abate. One the contrary, it would flare out of control, transforming him into a devastating demon of carnage.
