The spelunking party delved downward; the initial passage gave way to a round chamber containing a white, frozen pond, the end of the trail of ice that accompanied them.  The scent of snow and dust lingered on the near-still air; the absence of wind made the cave feel warmer than the outside.  Forgath brightened his spell, removing some of the red tint in the process; the brighter orange firelight coated the walls, revealing three exits from the chamber.  Plump looked around for a few moments before shaking his head. "Too close to the surface, but promising.  The ice on the ceiling means that there's plenty of water getting in; we just need to get a little further down."
