It appears things are as you suspected, Lord Vader. We are indeed hunted.

Anakin Skywalker, Jedi Knight, is just a memory. Darth Vader, newly anointed Sith Lord, is ascendant. The Emperors 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 Mastersand the truest measure of Vaders 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 resourcesby political power or firepowerand 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, its 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 planets 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.
