You step into the Atrium (either from a Fireplace or from the visitors entrance), and see other wizards walking through the hall past the Fountain of Magical Brethren. The floor is polished dark wood, and the ceiling is peacock blue with golden symbols floating across it slowly.

The fountain itself is made up of a group of golden statues depicting a wizard, a witch, a centaur, a goblin and a house-elf, all of which pour water into the surrounding pool.

The security gate can be seen at the end of the hall (OOC: Security check in is in a separate thread).
