Perhaps it's a rebel squadron that in the immediate past lost its carrier.  They may have just enough hyperfuel for a couple more jumps but not enough to make it back to the nearest rebel base?

I was personally thinking to make them originally be from the original timeline (the canon one) from after the Battle of Endor, before being pulled into this alternate reality while on patrol. That way they are familiar with everything yet unfamiliar to the new changes the suspicious figure made to the galaxy they used to know.

Also, where should I post the sheet? Here or straight into characters?
