This Week in the Universe: Aliens, Guns and How to Kick Ass

Hello every one. I hope you are all enjoying Destiny as much as I am. What's your class preference? I love the SunSinger, a lot of people don't realize it's potential. Anyways, aliens man. Where did they come from? A friend of mine mentioned that they never really explained that. The Vex were the focal point of the story, and sort of the Fallen at first. The other two races got shafted(except the Wizard of course...err Hive ;).) The guns though, they are a blast. Is anyone having fun just popping heads off like me for no reason for hours? I do it for farming and my Grimoire score, currently 1605. The Crucible is addicting too. The one thing I don't get is, if there are other people out there that aren't Guardians, why didn't we fight other races like the Exo, Humans and the third I can't remember? There are always those who side with the enemy. Peace, Admiral.
