Mosefra is the capital city of Paletn V in the Nymean Ascendancy. It has a population of six million mostly pharmaceutical workers and swamp gas refiners. It is the largest city on the planet and was the first Eriadi colony on the planet.

During the Vagaari War, the Vagaari attacked the planet in the Battle of Paletn V and occupied the city. While many civilians were able to flee into the nearby swamps, over three million did not escape. Of those, 200,000 were captured and processed by the slavers and taken to their slave ships for transport elsewhere. Only twenty thousand survived the resulting battle as many were killed when the warships they were on were destroyed by Nymean and Chiss fleets.
