Greer Sonnel was a human female pilot and the personal assistant of Senator Leia Organa. Sonnel was a racer who piloted a purple RZ-1 A-wing interceptor, the Ossifrage. Sonnel suffered from bloodburn, a rare affliction that ultimately ended her racing career. Some time later, in 28 ABY, Sonnel was chief of Senator Leia Organa's staff. She accompanied the senator on several investigations into Rinnrivin Di's crime cartel and the Amaxine warriors alongside senator Ransolm Casterfo, X-wing pilot Joph Seastriker and Korr Sella.
