On the other side of the room, a place Hermione had yet to explore, were four doors. Each door had the insignia of one of the four Hogwarts houses on them. Godric Gryffindor's door was ruby red with golden trimmings and handle. Salazar Slytherin's was emerald green representing his houze with a silver design. Rowena Ravenclaw's was blue but had a giant raven on it made of bronze. Finally Helga Hufflepuff's was a beautiful yellow with black and white badgers running around on the door. But what intrigued Harry was the protection on the doors. It had a glaringly white aura but what surprised Harry was that there were two layers. The bottom layer had a magical signature Harry didn't recognize but assumed to be the founder's signature. All of them had the Dark Arts Slytherin's had the most dark magic out of them with Gryffindor having the least amount. But the top layer, that one had a signature Harry recognized.
