The future will change...no matter what it takes. Alternate Xenoblade plotline. Events diverge at the end of the colony 9 assault. Indirect spoilers on account of different plot progression. I would recomend finishing the game before reading just in case.

The long battle it over. A new world has been created. The hero the homs, Shulk is now facing his most difficult battle, finding somewhere to stay that isn't a park bench. But a certain wing headed girl might be able to help.
