Celtic station is an 8 floor, deep space station, serving as a hub of commerce at the fringe of human space. Celtic station was one of the first to recive news of the alien threat and and to be infested. Celtic station was placed under quarantine after a service deck has somehow became infested. The effected deck has sealed off from the rest of the station and the frontiersmen summoned. If the frontiersmen arrive in time they will be phased into the (as yet) unaffected data centre. The station's 800 workers and 200 passing traders are relying on the TSA to prevent the spread of the alien threat and save their lives.
