The Mosdva were the second dominant species on Mastrit-PJ after the destruction of the planets ecology by the Ridbat species. They were mainly a nomadic species and developed slowly. Eventually an industrialist society was formed which lead to the enslavement of the Mosdva people for their technology by the Tyrathca who were a stronger and more aggressive species.
The Tyrathca eventually forced the Mosdva to build the 1283 arkships which lead to their dispersal amongst the universe, leaving the Mosdva behind in their asteroid habitats to witness the expansion of the system’s star and the destruction of their home planet.
After the expansion of Mastrit-PJ resulting in the destruction of their homeworld. The Mosdva have developed numerous disk cities made from the remaining asteroid habitats in this system where they have survived ever since.
Each disk city is divided into many dominions, most of which are independant from each other or have alliances amongst others. Feuds have occured between some dominions, sometimes resulting in the destruction of that dominions habitat which is sometimes left unrepaired.
Due to the lack of FTL spaceship development and the destruction of all habitable planets in the system, the Mosdva have been unable to develop any conventional trade or economic systems. Also due to the destruction or processing of most major asteroid bodies around the star, raw materials have become a rarity for the species and so any matter is highly valuable and sought out. The Modsva have devolped a way to mine their sun directly for hydrogen, and then transform it into other elements using nuclear fussion. While this activity is economically essential, it also has the unintended side effect of acclerating the aging of their sun, and thus in the long run, may be acclerating their extinction. Since Iron is the heaviest element that can be created this way, it is considered to be the most valuable.
