Rictus Disembodied Dentures

This is a lost artifact, known only through ancient stories of long-deceased ancestors, and has not been discovered in Ur. Pelagea, as a child, was the first person to notice this set of hauntingly grinning teeth, perched in a tree. Though no Humbabarian could dislodge them, many theories were raised and arboreal myths concocted explaining the genesis of the jaws involving death, decay, and flaying. The idea that Humbaba might have placed them up there just to mess with people was never discussed. It should have been.
