U.S.S Argos (Episode 1)
Starfleet lost contact with U.S.S Argos two days ago. Their last known position was in the XV-506 system.
They were returning from a vital mission given from Starfleet Command, but thats all the information you'll get from the briefing.
The rumor has it that U.S.S Argos was sent on a mission only known by the top admirals in Starfleet, to bring back something that would change the tide on the ongoing war with the Borg.
