You are standing barefoot on a cold, smooth stone floor. As you look around your eyes adjust to the lack of light and your nostrils fill with the damp, musty smell of old decay. You can feel a slight breeze blow against the back of your hands and you get the feeling that you are deep underground. After a few moments shapes begin to form out the blackness and slowly the outlines of other figures can be seen, they are all dressed in pale, sickly white, hooded robes, as are you. The walls of the room are covered in carved stone blocks, they seem misshapen and ancient and are covered in layers of slimy moss. The group is standing in a circle around what appears to be an opening in the stone slab floor, it is several metres across and in this light looks bottomless.
