With the loss of Alpha Centauri our logistics chain has been comprimised and we are no longer recieving supplies from Terra. COMSENFLT has ordered the fleet to break anchor and make speed for the Gliese 876 system. Admiral Sorenson expects to meet heavy reistance from Ghost forces still in the Alpha Centauri System. He also expects scouting forces in the Gliese 876, Tau Ceti and Sirius system. Comm traffice from the smaller task groups along the Sentai chain indicates roving squadrons of scouts from the Ghost fleet.
We have had no contact from Terra since the courier ship delivered the news that Terra was under siege. The lack of communication is worrisome and the Admiral believes our forces are better spent relieving Terra than guarding this wartorn rock. Sentai is important but if we lose Terra and the rest of the Sol system and their infrastructure then we lose the war and the fate of humanity is hanging in the balance.
12 scenarios tell the story of the Sentai Fleet's return to Terra and the long bitter fight against the Ghost Fleet.
