Wisely recognizing that discretion is, indeed, the better part of valor, the Wizards elect not to disturb the slumber of the great beast and withdraw. Upon reaching the ledge around the vast cavern again, they look more intently across the wide expanse. The ledge itself is thirty feet above the floor of the cavern, but still thirty to forty feet below the ceiling. Looking out across the large cavern is not that easy from your present vantage point, but even from here you can tell that it is far from pristine, with detritus and the occasional bone being randomly scattered about the floor. You can also see a large area of deeper darkness roughly 50-60 feet from the edge of the ledge on which you stand. This area extends for 100 feet or more from northeast to southwest, its northeast end, about 80 feet away from you, being the closest it reaches toward the ledge, and its southeastern end being the farthest from the ledge and from you, about 100-110 feet away. This area appears to be a sort of canyon in the floor of the cavern that reaches down who knows how much farther.
