Nerthus And Other Places

Future history backgrounds include repeated references to fictional places. Robert Heinlein's Future History has Luna City on the Moon, Drywater on Mars and Venusburg on Venus. Poul Anderson's Psychotechnic History has the colonized planet, Nerthus, which appears in four instalments and is referenced in a fifth. We see colonists on Nerthus, the Coordination Service has a base there and the Nomad ship, the Peregrine, visits there. Sandra Miesel tells us that:

"Nerthus grew into a prosperous hub of its galactic sector, attracting visitors from other worlds and cultures. It even hosted a regional base of the Stellar Union's peace-keeping Coordination Service."

-Sandra Miesel IN Poul Anderson, The Psychotechnic League (Riverdale, NY, July 2018), p. 42.

Although Anderson's second future history series, the Technic History, features many fictional places, it does not focus on any particular locations - its equivalents of the city of Stellamont on Nerthus - but instead shows entire planets, notably Earth/Terra and Gray/Avalon, at successive stages of their future histories.
