Professor Edward Mostravarus's Office

After the last staircase of the tower lies a big wooden door, with a single insciption on it. Behind it, there's a large wooden room, lit only by some candles, long and narrow windows and a fireplace. Several bookcases are standing against the wall, while some paintings, statues and a blue carpet over the floor give some life to the dark office. There's a huge window that covers all that piece of wall at the far side of the room, and in front of it there's a solid ebony desk with one chair at one side, two at the other. In one corner, there's a big cauldron, and next to it an odd looking pile of dust, carefully placed inside a stone box.
