Darth Vader and the Ghost Prison #4 represents the fourth installment out of five in the Star Wars: Darth Vader and the Ghost Prison comic book mini-series, penned by W. Haden Blackman.
Vader is pitted against the most perilous convicts The Prism holds, while Cadet Tohm observes the Dark Lord exhibiting his most intense—and most unforgiving—behavior.
This encounter deeply affects the young man, and Tohm emulates Vader's actions, uncovering a power—and a sinister side—he was previously unaware of. He is rapidly evolving into the type of officer that will define the Empire. However, the ultimate challenge remains: reclaiming the Imperial Palace from the rebels. A skirmish today . . . a full-scale conflict tomorrow!
