Floki Boombeard is a mad dwarven artificer whose explosive contraptions are as dangerous to himself as his intended targets. His right hand is a large hook, and several burn scars adorn his face and arms.
Floki serves as the 'surgeon' aboard the Cruel Mistress, a pirate ship, under captain Angelica. In combat, Floki wears lit fuse matches in his bushy black beard to light his grenades on.
