Bartholomew Stormtamer's First-Mate
The Hammerhead is a massive, hard man of the sea. Born out of a strange union, he has lived his entire life with fin-like bone protrusions jutting out from his forearms. It is rumored that they used to be red, and that he has had them tattooed blue to hide his origins.
In battle, he is known to wield a massive warhammer. Whether this is where he got his nickname or not is unsure.
