The Solar system? Come now, Destiny can go far beyond the Solar system with this. For Example.... The Darkness comes and let us say... We lose. Then, we have to escape into a new realm with the Traveler as out "ship". Earth is gone and now we must establish a new home and find a weakness to the darkness as it chases us across the universe. Or... We expand into other solar systems pushing the darkness back as we try to find the source of the darkness. And, as we get closer, the enemies become more and more deadly. Our only hope of survival is to combine our strengths. PlayStation and XBOX servers open and we cross play against the darkness. The end is never ending.
