When you enter turn into a Mouse and enter the Mouse Hole. Click the Essence of Cunning to gain +1 to that stat. Head back through the Mouse Hole and open the door to the hall, then go to the first room on the right. Defeat the Burning Templar and move to the next room. Open the door here to find more Burning Templars. The Massive Door cannot be opened and the other door has fire behind it so use the door at the top of the stairs. Follow the path avoiding the flames until you find a Mouse Hole, use it. Defeat the Templar Dreamer to obtain the Burning Man shapeshift ability. Use the Fade Pedestal and choose Mages Asunder.
