On the Planet Belassa, parts of a secret new weapon are being built by the Empire. Darth Vader and Grand Moff Tarkin are present to make sure the secret stays a secret – and they are joined by none other than the former Jedi apprentice and Rebel leader Ferus Olin. But is Ferus Olin really on their side? Or is he a double agent, trying to save his planet and steal the Empire’s plans? Ferus must guard the secret of his own allegiance…or become yet another victim consumed by the dark side.
