Ok so bare with me Time has passed and the vanguard has reclaimed earth and the moon and are moving towards Mars The cabal have been silent for awhile, although a call has been made to the vanguard asking for help and to aid them in reclaiming Mars. Skeptical the vanguard helps them then leading that it was rouge group of cabal. Thanking the guardians the new formed regiment asks to join the vanguard as a new ally. After a lengthy discussion the vanguard agrees and the regiment reveals that they have a whole fleet ready to fight back and topple the emperor of their home world. Skipping forward this will introduce space battles, new allies, weapons, social space, etc... In the end you earn the new social space at the emperors palace after you drive him out ( end of story) The raid would include the emperors retaliation and would end with you ending him and his regime for ever
