Stop the cabal from destroying the tower. By lore they have that capability Make this the most ass kicking raid ever.. First you fight the cabal at the tower. The stranger shows up and says they aren't just going for the tower but every planet. Our party, the stranger and eris eridicate the cabal from the moon. Next we partner up with the queen and stop them on Venus. Finally the whole party lands on mars meeting up with xur. Stop the cabal once and for all . The stranger knew of this when she communicated with an unknown entity in the cinematic where she calls the ghost little light.. Since we already completed the vaults on the moon and Venus it's all about this war against the cabal to save the last city . After we kill the cabal leader we all die as well. Now the cinematic with the traveler hovers over us and revives us all. The traveler protected us.. Again. :) Did I get the job?! Lol
