One day in fairyland, there is an immensely bright flash of light a about a mile above the ground. Something like a metal house is suddenly flying through as if it came through a portal, faster than all but the fastest fairies.

It's flying, not directly down, but still very much towards the ground. It does not take long for it to stop flying and start carving through earth and trees. Eventually it runs out of momentum near a certain lake. The thing seems to still be in one piece, which is rather miraculous considering the two miles of destroyed trees behind it.

After a few minutes, a mortal covered in unusually bulky clothes emerges from the thing. All that is visible is his face. He starts inspecting the outside of his space oddity.
