City gets rekt by cabal our vaults destroyed somehow we lose our light and then we go to the guardians beyond the reef that efrideet spoke of when she returned in the cutscene. There were guardians beyond the reef that found new ways to use the light. Once we take back old ground and conquer new land we get revenge after the story in our very first cabal raid.

I am putting my money on: We are send to go somewhere and our space ship blows up in a blizzard. We are stranded in the light zone and have just one hour to get the anti vitals in the dark zone and gear up....because we are also infected with the siva virus.
