Into the Taboo Lands
As the party moves past the shattered skeletons, they note that the injuries obvious on them are similar to the skeleton found under the tree... first by Sheldon, then later by the entire party, just before the robot 'dog' attacked. They had holes punched in them, not unlike what happened to poor Frank...
Doubling back, Nic took the time to search the bodies. They were long dead... not that he was an expert, but he'd guess they'd died before he was born. Amongst the skeletons, he found a sealed metal box, and a strange mask with insectoid eyes and strange canisters on either side of the 'snout'. Both were easily portable, although the box was a bit heavy.
