Soo.... are you guys accepting new people or should I go loiter somewhere else? ;)

I have a few ideas for the character's reason for showing up. Here's a few:

1. Sent on a recovery mission

2. Passerby crash landing due to whatever fate decided to rain down on his ship

3. Private Contractor on a different mission to the planet

4. An explorer of sorts, discovering the planet. 

Just a few ideas I've been tossing around in my head, particularly number 2.
