The New Paris System was colonized in 2077, prior to the Avalon colony's founding in the Vega System. However, Avalon's proximity to Earth made it a more attractive colony. For a century, it remained an unremarkable system of the Earth Federation.
The digital gate project changed that; with sudden instanteous transport between Earth, Avalon, and New Paris, it became a major throughfare for military and commercial traffic. WIth the destruction of Earth in 2198 by another Bug asteroid, Avalon became the new capital. After the 1st Civil War, the system became a cheaper alternative than the capital planet for the growing number of bureaucrats who served the Federation. It remains today one large suburban star system. Outside of its cities of cheap housing and smaller towns of quiet family living, its farmland helps feed the urban populations of itself and Avalon. This status as a supply hub for the enormous population on Avalon led to it retaining its digital gate and jumpgate connections, even as most other jumpgates were shut down after the Ascension War, as a necessity for feeding the masses on Avalon.
The New Paris system was entered, but not attacked, by the Caal invasion fleet en route from Jennifer's Star to Avalon. This miraculous "New Paris New Passover" has made the planet a hotbed of loyalty to the new Holy Terran Empire and a center of fervor for the Cult of the Emperor. This system's importance as the gateway to the Capital and center of its supply network led to it being both heavily fortified and entrusted to only the most loyal of noble houses.
