Mosont was first a city-state and then the capital of Ginsag. It was founded by Miernan Kolden somewhere in the beginning of the 17th CSR, although almost no historical data exists either of the founding or of Miernan's life.
Known for its fertile soil, Mosont became wealthy through farming and trade deals with other regions. This was expanded by its later governor, Elsk Normo, making Mosont one of the wealthiest cities between Loodon and Taverda rivers.
The superhero warrior Ginsag was born in Mosont in the middle of the 17th CSR and became its ruler. He expanded the country, while making Mosont its capital city. It was then ruled by Ginsag's sister, Nalsag.
Mosont was destroyed by Tref in 1712 SR, in a campaign that effectively ended the state of Ginsag. Over a century later, Dod Overpol founded Dav where Mosont once was.
