Georgesstar
Georgesstar is the administrative centre for much of the British extrasolar holdings, this role taking upon a new importance since the Solar system was cut off from the rest of the galaxy by the laying of a minefield.Settlements in the Georgesstar system (named for King George VII) include two cities upon the snowball world of New Antarctica. Although the atmosphere here is non-toxic and non-corrosive, it is also non-breathable, so residents and visitors alike must wear oxygen masks at all times.
Kingston, the larger and older of the two, has most of the civilian facilities and is a popular skiing resort. The other, Churchill, is a military-industrial complex, featuring, the only extrasolar shipyard owned by the British, and a BAE research facility.
Another world in the system, New Jersey II, was the site of one of the earlier mining colonies. Even the once-bustling capital of St Helier is now a virtual ghost town as the initial "ore rush" collapsed. The colony now ekes out a living by getting paid to store high-level nuclear waste.
