Anakin Skywalker, Jedi Knight, is just a memory. Darth Vader, newly anointed Sith Lord, is ascendant. The Emperor’s chosen apprentice has swiftly proven his loyalty to the dark side. Still, the history of the Sith Order is one of duplicity, betrayal, and acolytes violently usurping their Masters—and the truest measure of Vader’s allegiance has yet to be taken. Until now. On Ryloth, a planet crucial to the growing Empire as a source of slave labor and the narcotic known as “spice,” an aggressive resistance movement has arisen, led by Cham Syndulla, an idealistic freedom fighter, and Isval, a vengeful former slave. But Emperor Palpatine means to control the embattled world and its precious resources—by political power or firepower—and he will be neither intimidated nor denied. Accompanied by his merciless disciple, Darth Vader, he sets out on a rare personal mission to ensure his will is done. For Syndulla and Isval, it’s the opportunity to strike at the very heart of the ruthless dictatorship sweeping the galaxy. And for the Emperor and Darth Vader, Ryloth becomes more than just a matter of putting down an insurrection: When an ambush sends them crashing to the planet’s surface, where inhospitable terrain and an army of resistance fighters await them, they will find their relationship tested as never before. With only their lightsabers, the dark side of the Force, and each other to depend on, the two Sith must decide if the brutal bond they share will make them victorious allies or lethal adversaries.


絕地武士安納金‧天行者，只是過往；新上任的西斯王達斯‧維達，君臨天下。暗黑君王選中的徒弟很快便展現其誓死效忠暗黑勢力的心。然而，黑武士軍團在過去就以欺騙、背叛以及掠奪篡位而聞名，因此，維達的忠誠與否也尚未能定奪。如今，在賴洛斯這個星球上，一個長期提供奴工和俗稱「香料」的麻藥，讓暗黑帝國日益增長的地方，由理想主義的自由戰士查姆‧新杜拉和心懷仇恨的前奴隸伊斯佛所帶領的抗爭運動，正如火如荼的展開。但是，暗黑君王白卜庭卻想運用政治權力及火力，支配這危機四伏的世界，接管珍貴資源，他無所畏懼，也沒有人能阻礙他。在殘忍無情的弟子達斯‧維達的陪同下，黑暗君王賦予徒弟一個特殊的使命，來確保他的意志已成熟。但對查姆‧新杜拉和伊斯佛而言，這是一個絕佳的機會，能直搗黃龍，一舉殲滅這已滲透整個銀河系的殘暴獨裁勢力；對暗黑君王和達斯‧維達來說，賴洛斯星球的狀況不單只是平息暴動而已，當他們遭伏兵攻擊墜落到該星球時，一片荒涼之地和一群反抗軍正等著他們，師徒二人的關係也將受到前所未有的考驗。僅擁有各自的光劍、黑暗原力以及彼此得以仰賴，兩人必須決定這聯繫彼此的殘酷關係，將使他們成為勝利盟友抑或死對頭。
