You were bored to death. The castle was empty, the servants in the kitchen or somewhere else. The long corridors were punctuated by the sound of rain. You finally found yourself in the attic, after wandering for an hour over the thick carpets, up the spiral staircases, and behind the stained-glass windows. The attic is large. Very large. Filled with old junk, trinkets, and broken old weapons. In a dusty corner, you found an old lamp. Silver, with small, intricate runes on the sides. To see them better, you blew on it, rubbing the metal a little.
"Good heavens!"
There was a furious, white flash that made you drop the lamp against the wood. You stumbled backward, tripping over an old rocking horse, ending up on the floor, amidst the rustling of your dress. Someone is standing in the attic.
