Given the nature of Fate, you were probably known to be in the area at the airport, sent over initially for reasons you didn't understand and weren't privy to, and just filled in about the Luminary once you landed as you were given an escort over.  But you're free to play the officer and all such, or just to skip over it to arriving, at your preference.<br/><br/>Much of the scenario is VERY vague, so I'm happy to let the PCs fill in the blanks and figure out what sounds fun and appropriate.
