Slytherin Common Room
The Slytherin common room lies behind a cunningly concealed entrance down in the dungeons. As you'll notice, its windows look out into the depths of the Hogwarts lake. We often see the giant squid swooshing by — and sometimes more interesting creatures. We like to feel that our hangout has the aura of a mysterious, underwater shipwreck. And once you're in, you're in. Nobody backs out later from being a Slytherin.
A few more things you might need to know: our house ghost is the Bloody Baron. If you get on the right side of him, he'll sometimes agree to frighten people for you. Just don't ask him how he got bloodstained; he doesn't like it. The password to the common room changes every fortnight. Keep an eye on the noticeboard. Never bring anyone from another house into our common room or tell them our password. No outsider has entered it. 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. Silver lanterns hang from the ceilings. They're starting to put up tapestries depicting the adventures of Slytherin alumni on the walls. You'll sleep well; it's very soothing, listening to the lake-water lapping against the windows at night.
Don't get too comfortable though, because, remember, you could be between someone else and their ambition, and we students of Salazar prize a delicate removal more than a blatant confrontation, and see artistry in a well-woven web, whatever it's make-up may be.
