I am inside at last. It took me several days of watching and waiting, but I am patient. I was rewarded with a mass exodus at twilight yesterday. The entire group, accompanied by their cave bears, left on some quest that was doubtless of great importance to them. I am elated to report that the rumors are true. The ogres residing here are indeed unusually intelligent. I will take diligent notes for the three weeks my supplies will last. I can already hear the applause when I present my findings to my colleagues in the Imperial City, once this foolish war is over.
