The sack crumbles into bits as Marcus pulls it out of the alcove, scattering its contents into the hall. The contents are three small statuettes, about the right size to be held in two cupped hands, along with numerous stone fragments, obviously from other statuettes that were crushed by the stone slab. The three intact statuettes are of a grand palace, a slim spire with eight connected smaller towers of different heights, and what looks like a grand stadium.
Brad pulls the coat out, dragging some bones with it. The coat, unlike the sack, is still in fine shape. The leather is supple, showing no signs of age. After shaking the broken bones out, he searches the pockets to find a small, wood-bound notebook with an eight-pointed star burnished on the cover. The yellow, brittle pages contain some sketchy maps and rather cursory notes. The information is a bit difficult to read, but it's in English. Reviewing the pages reveals the following information:
This guy was obviously part of a small group of treasure hunters exploring this cave for "arcane relics." The group had six members: Uhle, Claus, Anders, Wayne, Jacob, Fred, and the author. Together, they entered the cave and got as far as the big room with the lanterns. The description of that part of the cave complex is consistent with what you've seen so far, except that all the lanterns were present. Wayne was badly burned by the trap in the sarcophagus lid, but they figured out how to operate the elevators and decided to split up to explore further. Jacob was planning to climb up to a passageway above the blue lantern. Fred was going to descend the elevator beneath the indigo lantern. Uhle, Claus, and Anders descended an elevator beneath the green lantern (which apparently was working at the time this expedition took place). They took the red lantern with them, because the group didn't have enough light sources of their own. The author descended the elevator beneath the yellow lantern. The injured Wayne remained behind in the main chamber. He had taken the indigo lantern an was using it for light. The notes indicate the group found one interesting item in their brief investigation: an intricately carved armband bearing a repeating leaf motif. Wayne was carrying that.
