Albus followed a path, unsure of where he intended to go. He led them to one of the old school toilets. This was a room that was off-limits for castle staff and so had not been kept in good condition. Opening the door, the two were overcome by a pungent smell. There was mould and rust on the rims of the toilet seats and around the walls. Their feet crackled as they stepped on small shards of broken glass.  Even Ligo looked a little perturbed, wondering why they were here. While he was pondering this, he heard the Lord of the Castle speak in an ancient serpent tongue. He noticed then the serpentine quality of Lord Albus, his scaly skin, bright yellow eyes, and squashed nose with slits where the nostrils should be. The hissing voice seemed to have an effect on the room, Ligo felt the floor vibrate, and a fountain in its centre started to rotate, revealing steps leading below to the lower floors of Hogwarts Castle.
