Swansong is a well-populated colony in the Cygnus Sector, recharted by the Pathfinder Ship Odyssey in the 72nd Solar Century. Its surface contains two large continents, Swan and Vestia, each claimed by a different nation-state. The Swans and the Vestians have a long history of warfare and hostility, and only came to an accommodation after long negotiations with the New Commonwealth; which they subsequently joined.
Swansongians participate in the exploration and defense of the New Commonwealth, serving in the crews of Explorer, Defender, and Supply ships. Swansong has constructed a small fleet of fast attack corvettes, that operate in pairs; one crewed by Swans, one by Vestians.
