Gath'Ilzogg is the leader of the Blackrock attacks on Stonewatch Keep and of the raids against the township of Lakeshire. His axe was made by Martek the Exiled.
Gath'Ilzogg is extremely dangerous and led those brutes into battle, killing many innocent humans... He is reportedly holed up in the recently conquered keep plotting the Blackrock clan's further crimes against humanity.
On his side is the Black Dragon whelp Singe, who maybe a present of Victor Nefarius for the successful attack on Stonewatch Keep or he is even a embassador of him.
