Purge is a series of connected one-shot comic issues set as a follow-up to Revenge of the Sith. A handful of Jedi who survived Order 66 unite to do something, once and for all, about the evil Galactic Empire and the Emperor's dark enforcer. Vader isn't upset that the Jedi want to resurface, because he has a singular focus—to track down Obi-Wan Kenobi.
