Recalescent Stone is an Ornament in Torment:Tides of Numenera.
Recalescent Stone Information
Attached to a fine chain is a hunk polished meteoric metal fashioned into the shape of an eye. While cool to the touch, it has the bright glow of cooling metal that does not seem to dissipate. You can sense a barely contained surging power behind the glow, a promise of power to those who can control it.
You gained this item at great cost by plucking it from a malevolent scaled statue.
