The Threat From the Deep
Ring of the Darkhidden
A ring of peculiar origin
This ring will render the wearer invisible to creatures with Darkvision – provided that is how they are seeing. Any light in the area will reveal the wearer as normal.
Presumably forged far beneath the earth in places that never see the light of the sun, the Ring of the Darkhidden is a black band, inscribed with dozens of closed eyes. Its magic conceals the wearer from creatures that do not rely on the sun to see.
