After returning to Kashyyyk to meet with Chief Tarful, Cal Kestis soon felt a tremor in the force. He went to investigate, only to find he was lured there by the 9th Sister Inquisitor. A Sniper bot and a Death Trooper took several shots at Cal while the 9th Sister mocked him. Cal quickly ran for cover as the Combine Helicopter and hunter killer dropship also opened fire on Cal.
