You have just descended from the highest heaven, from the Empyrean (the highest part of the sky filled with fire and light). you have changed your form, because the sight of your real face has always frightened people and angels who have never been to the Highest heaven.

You haven't gotten used to using your human form yet, so as soon as your naked body was on your feet, you fell. A young man, I think it was Ian, ran up to you and covered you with his cloak, and then helped you to your feet.
