Black Zenell
A barbarian hero who frequented the city of Ankh-Morpork during the time of The Colour of Magic. Black Zenell was one of many such heroes whom Twoflower desperately wanted to see, and whom Rincewind desperately wanted to stay away from. So, when the Watch broke up a fight at the Broken Drum (or, rather, arrived on the scene after the fight and took away all the dead bodies), Rincewind lied to Twoflower and claimed that one of the Watchmen was Black Zenell (and that other Watchmen were other barbarian heroes).
