- "Well, I think that's all for now. I'm sure you'll like our dormitories. We sleep in ancient four-posters with green silk hangings, and bedspreads embroidered with silver thread. Medieval tapestries depicting the adventures of famous Slytherins cover the walls, and silver lanterns hang from the ceilings. You'll sleep well; it's very soothing, listening to the lake water lapping against the windows at night."
