His Most Ferocious Majesty, Turrosh Mak is the Despot of the Orcish Empire of the Pomarj.
An unattractive half-orc, he is an intelligent and ruthless warrior, a survivor who will use any dirty trick at his disposal to stay alive.
Turrosh Mak is a founding member of the Slave Lords and is still closely allied with their present incarnation.
There is an article about Turrosh Mak at Greyhawk Wiki.
