The blackwater company
A mysterious crow-man. We're pretty sure he's a man. Nobody's been able to check.
Kidney is an enigma wrapped in a mystery covered in feathers. He’s called Kidney because whenever someone asks why he’s called Kidney, he punches them in the kidney. He can speak Common perfectly well on his own, but prefers to either croak and caw in the language of his people or imitate what others have just said.
He might actually be a woman; nobody’s really sure. The last guy to try and find out got punched. Take a guess where.
