Shadows of Nibarra
The Ashglass Rod is an item found on the arcane workbench of Agera of the Shadow Face beneath Stormcrow Tor.
The rod is 18” long, its sides planed with 12 sides. (Each end, therefore, is a regular dodecagon 2-3” across.)
The rod is carved from a single piece of volcanic glass. Each end shows a stylized dragon head, possibly the symbol of an unknown power named Orelus. This symbol is formed in lines of some silvery metal somehow embedded in the glass.
