Renzik

Renzik is a goblin member of the SI:7 located in the headquarters in Old Town of Stormwind City. Renzik has connection both to the Hidden Circle in Ironforge as well as the rogues in Darnassus. He is Mathias Shaw's second in command.
Because most SI:7 agents are members of recognizably Alliance races, Renzik often serves as the organization's spy in Orgrimmar and other Horde territories. Renzik doesn't like interacting with others, but the pay is good and he can honestly say he is respected. Wowpedia -
