Agent for the
Shadows aboard
Earth Alliance station
Babylon 5, where he served from 2258 to 2261. In his former life, an officer aboard the
Icarus on an expedition to
Z'ha'dum. (To this end, was briefly held for questioning by Captain
John Sheridan in 2259.) Returned to Z'ha'dum to negotiate with Sheridan in late 2260. In 2261 fled to
Centauri Prime to form a Shadow colony, but was killed by
Londo Mollari to atone for his involvement with them.
(My favorite B5 bad guy, BTW.)
