Oh what a tangled web we weave ...

Breccia bravely tells the others to return to Elias while he scouts the area. His infravision works better without the interference of other light sources, so this may be a sensible move. While they return the way they came, Breccia looks around. Ahead he can make out a room and the cold stone of a large table in its middle, with a cold figure or carving atop it. He can smell bits of gold in the dust around the table. As agreed, however, he sneaks down the longer chamber through ancient dust and bits of stone. Within five minutes he has reached the edge of another, smaller room. The floor of the room is covered in small lumps making an uneven surface. Bending down, Breccia investigates and realises that they are the corpses of rats. He is about to step further into the apparently empty room, when a shape detaches itself quietly from the shadows, emerging out of a previously unseen hollow in the floor. A giant spider! And not 15 feet from Breccia!! 

So this is what the world looks like through infravision!
