The upper reaches of the chamber are cloaked in deep shadows. Strewn among the unusually large stones and rubble are a litter of cracked bones and other less savory detritus of death. One wall is cloven with an ominous crack running from the floor up into the darkness above. Many smaller spidery lines fork off from the main split.
