Captain Bogrull the Bear

Before he was a pirate Bogrull was the victim of a curse. A witch killed his brother and transformed Bogrull into a horrible monster that most would attack on site. In fact Bogrull was the name given to him by locals when he was a monster. Even after he was freed from the curse the Captain chose to keep the name Bogrull. Bogrull ended up on the Black Gem when he was taken captive as a prisoner. Captain Iron hand offered him a spot on his crew and Bogrull to it.
After Iron Hand died Bogrull stepped up and took the spot as captain. He captains the Silver Hand pirates to this day. He brings fear and takes silver.
