Sirius Coalition Cruiser
The Sirius Coalition has its roots from an old mercenary coalition in Sol and nowadays its members are some of the most powerful and notorious mercs out there. They show up in the most volatile and troubled regions of space and their presence is enough to get them what they want, sometimes even without firing a single shot. Not much else is known about this group as they usually kill anyone that might hold any useful information about them.
