Lesser idol of Tempest
From ThresholdRPG Wiki
This idol is a four inch tall cylinder formed of tin reeds side by side. A tiny, crudely formed peregrine falcon is perched in the center of the reeds. Each reed is hollow and has small holes in it so that when a breeze blows a whistling sound can be heard. The base of the cylinder is polished tin, weighted in the center with lead so that it stands solidly.
