Cosmo Babylonia

Orginally named Frontier IV, it was the first colony to be attacked by the Crossbone Vanguard. It is then taken over and renamed Cosmo Babylonia as the capital of Ronah family's new aristocratic nation.

History
A new nation established by the Crossbone Vanguard, made up of the captured space colonies of the Frontier Side. Under the leadership of the Ronah family, Cosmo Babylonia is dedicated to the principles of aristocracy and noblesse oblige. Cosmo Babylonia soon establishes an alliance with the Jupiter Fleet, allowing it to stave off Earth Federation interference with the threat of an energy embargo.

The Crossbone Vanguard continues to hold control over the Frontier colonies, until the return of Cecily Fairchild in U.C. 0125, who denounces Meitzer Ronah, resulting in a civil war between the Ronahs and their respective supporters. Due to the in-fighting and the added weight of repercussions demanded by the Earth Federation for taking the Frontier colonies, Cosmo Babylonia ultimately collapses in U.C. 0128.
