Luke becomes resolute in his mission to locate Lune Divinian after the high-value prisoner vanishes from his holding cell located on Yavin 4. Div, the solitary connection to X-7, the assassin dispatched with the intention of assassinating Luke, represents the only possibility of maintaining an advantage over the Empire.
X-7, having broken free from Imperial imprisonment, finds himself spanning the vastness of the galaxy. Torn between the events of yesterday and the reality of today, X-7 is compelled to confront the one conflict for which he lacks preparation: the struggle for his own sense of self. However, his intense bewilderment amplifies the threat he poses.
A coincidental meeting coupled with the reappearance of a character from bygone days converges X-7, Luke, and Div, setting the stage for a climactic confrontation poised to either expose all truths or result in their utter annihilation.
