(semi-spoilers)
The opening scene has this girl falling from the sky. She doesn't seems scared, at least at that moment. A crow flys along with her and trys to to pull her up. She says it's no good, but thanks the crow. She finally gets close enough to see the country-side, this is when she kind of panics.. but it cuts off there. You'll see a hallway and hear foot steps and slowly out of the darkness of the hall a person is walking with a large box, but she has this unusal glow over her head(a halo?) and can see tips of small wings from her back...
I think I'll leave it that, I don't want to lead you too far in.
