Filigreed Onyx Amulet
amulets found on slain & captured tengu
An onyx filigreed amulet of similar artisanry to the Cube. The tengu captured after the four were ambushed upon approaching Mt. Shingo said that all of the tengu in the Lower Rift Valley had accepted them — or been forced to wear them. Although the individual amulets appear to be magically inert, Harrow theorizes that they are somehow being used to control the tengu in the valley.
