Join the Guardians of the Galaxy!
You are a kid on Knowhere. You're lost and alone. You've been hitchhiking and stowing away from your home planet to this giant skull, but now you're stuck. You can't find someone to give you a ride.
You're not picky about where they take you: All you know is that you can't go back to being a Kree battle-slave. You just need to get as far away from the Kree empire as possible.
