- ―A stormtrooper and Chelli Aphra
Micro-trackers were small tracking devices that could be used to follow an individual's location. After encountering her on Skako Minor, Magna Tolvan planted a micro-tracker on Doctor Chelli Aphra. She tracked her back to Son-tuul, where Imperial forces defeated the Son-tuul Pride and imprisoned Aphra in Accresker Jail.
