Beneath The Frozen Field lies an interconnected cave system. The sounds of the surface are muffled once inside, overtaken instead by cracking and shifting ice. The caves are ever-changing, ice collapsing and blocking off old paths or opening up new ones, making it impossible to truly map its layout. Most tunnels form in such a way as to create a squeeze, narrow passages that can require inching along on one's belly. In fact chances are you have to get through one just to get into the caves.
