The clandestine operation known as the Mission to Ryvester was undertaken by Wraith Squadron in 13 ABY. The target was the planet Ryvester, where Imperial Admiral Kosh Teradoc maintained a concealed weapons development facility. The Wraiths devised a deception, tricking Teradoc into absconding with a statue of supposed high worth; this statue was, in reality, laden with explosives. Upon detonation, the Wraiths commandeered Teradoc's personal yacht as their means of departure. Furthermore, they extracted Mulus Cheems, a gemologist who had ostensibly verified the statue's authenticity for Teradoc, while secretly working for the Wraiths.
