Syndicate
A group of people who have been fucked over by Nanotrasen and now hate them. They are directly responsible for two types of antagonists that will attack the station, the red-suited Nuclear Operatives whose orders are to recover the Nuclear Authentication disk and use it to obliterate the station, and traitors, saboteurs and assassins disguised as normal crew-members who have access to incredible technology and gear and who harbor a variety of sinister objectives (as well as absolute immunity from anti-griefing laws.)
