Star-streamers were passenger-carrying starship vessels. At some point before 10 BBY, during the Galactic Empire's reign, the Besalisk named Dexter Jettster journeyed to Athus Klee, a world in the Tingel Arm, aboard one of these star-streamers. Upon the vehicle's arrival, the other passengers rapidly exited and proceeded to the Spacers' District; by the time Jettster descended the star-streamer's ramp, all of the nearby inn accommodations were completely occupied. Jettster subsequently documented this event in the book that would eventually be titled Smuggler's Guide.
The inaugural mention of a star-streamer occurred in Star Wars: Smuggler's Guide, a 2018 reference book authored by Daniel Wallace.
