This story follows the two Wilson Pete instalments by divulging more information about the planet Nerthus which is about 300 parsecs from Sol and is a base planet for the Coordination Service. This is the first mention of that Service and we have not yet been told that it is a branch of the Stellar Union.
"Gypsy" told us about the beginning of the Nomad culture although the interstellar rovers were not yet called "Nomads" then. "The Pirate" will introduce Trevelyan Micah of the Coordination Service. Finally, Trevelyan will meet Nomads in Stellamont on Nerthus in The Peregrine. Multiple narrative strands converge for a climax of the Stellar Union period of the Psychotechnic History.
