[Bozos of Bones]

The myriad of hints were enough for me. SPOILERS AHEAD! The Wilderness lore skill finds footprints where the man's camp is; the dying man says he fell on some wolves, yet he is lying ontop some disciples; the Andorian ranger mentions something odd; the den smells of carrion and he warns you not to touch it. There's plenty of hints for most every situation in the game, you just need to connect them.
