Lesser idol of Set
From ThresholdRPG Wiki
This polished copper idol is formed of a flat, thin panel mounted inside a black wooden frame. Crudely engraved into the copper is a giant cobra spreading its hood in a threatening display. Tangled with the snake's long body are strangle-vines, the entire mass so woven together it is difficult to tell which is vine and which is snake. There is a sturdy hook on the back suitable for hanging.
