Reno was a businessman who sometimes operated on Babylon 5. He and his men found people and objects for a commission, and were payed via an account on Earth.
In 2258 he and his men made a business transaction with Ambassador Londo Mollari. The Ambassador received The Eye, an ancient Centauri artifact, in exchange for a large sum of money payed for by the Centauri government. When questioned about the means by which Reno and his men found The Eye, Reno told Londo that he wouldn't want to know. [1]
