While exploring a newly discovered star system, the Callisto is sent to an isolated planet where the dominant species, the Liraxans, are an advanced telepathic species with a rich history of isolationism. The Liraxans have recently begun exploring beyond their world and are seen as a potential ally, though they are cautious and mistrustful of outsiders.

The Callisto is tasked with making first contact. Through a series of tense but ultimately successful negotiations, the Liraxans agree to share their knowledge in exchange for the Callisto’s assistance in resolving an ancient conflict.
