Tanner Mirabel was a former soldier/assassin from Sky's Edge, later becoming security chief to arms trader Cahuella. A ruthlessly efficient and intelligent fighter, he failed to prevent an ambush, and accidentally caused the death of Cahuella's wife, Gitta. His mind was subsequently trawled by Cahuella and his memories and identity used to create a disguise, allowing Cahuella to leave the 61 Cygni A system seeking revenge, while Tanner was left for dead as punishment for his failure.
