“The door had six knobs on its inner side: the uppermost, which matched the outer one, a square of frost-furred crystal, and five beneath it, placed in an uneven row. The first two were of some sort of dark stone, one icy and the other matte and slippery-smooth. The fourth had the look of a tiny aquarium, a cylinder of turquoise sea shafted with sunlight. The bottom two were made of wood. The first was pale, carved with an intricate floral pattern. I could not tell if the second was similarly decorated, for it was largely covered in a wet moss woven with constellations of tiny white flowers.”
