The Kastle
The Kastle is the main Coalition Military Space Station in the K'oviin Expanse.
It is nearly 4 times as large as the other stations in the system, and able to comfortably hold a garrison of 500,000 personnel.
However, since the end of the war, it has been home to not only its full garrison, but an additional 2 million refugees from the destroyed empire planets.
It is also home to Outpost Kilo, home of the Killer Kilos, an elite unit of Coalition Commandos.
