Hopefully its some sort of manufacturing facility. Either making Cabal weapons of war, or Vex machines. Shutting down a major manufacturing facility would hinder all operations within our solar system, making prolonged war nearly impossible. Anyways, something like this would be cool, because it would make our actions seem like they have consequence, and give resolution. Both are necessary for good storytelling. Unfortunately, Destiny must persist far longer than 1 game, so any conflict resolution is unlikely. Probably kill another God I guess, which is wierd, considering how important Gods are, or maybe showing us how [i]unimportant[/i] they are.
