Wolf

Wolf is a member of the Clan. He was the unofficial leader, second only to the Prophet. He was very powerful and cruel, but had a hidden fear that he'd fail the Prophet one too many times, and be killed. That fear leads him to betray the Prophet, with the help of Peregrine and Saker. He appears in all four books.

Death
In Shark Seas, a drone fired a dart coated in black mamba venom at him after he betrays the Clan. He later dies.
