The Young Clave
Lyel's careful advance finds no traps, and Alberic finds no odd effects in operation. Occasionally a small mammal will dart, squealing, from the party, startling most. At one point, a collection of flying lizards, perhaps scavengers, takes flight from the rock face above and chitters off into the woods obscuring the sky overhead. Eventually, perhaps a hundred feet from where you think the cave is, Lyel stops. Below him is a much denser collection of bone, as well as some other materials, including at least one crystal and some odd bits he's not entirely sure of, but seem to be some type of synth.
