A stormtrooper deserter refers to an individual who previously functioned as a stormtrooper within the ranks of the Galactic Empire. This particular stormtrooper's desertion from the Empire was triggered by an action he undertook during a mission that occurred on the planet known as Aleen. Following this event, he, along with a pair of fellow stormtroopers, established a life on Nothoiin, where they took on the responsibility of caring for a young Aleena child.
