Signet of the Kindred

Wondrous item, artifact

This strange device is normally 4 feet across and 1 foot thick, shaped like a three-pronged cross of dull blackness.

It constantly emits darkness in a 20-foot radius. Anything that enters the darkness is instantly transported to the Tourbillion, a teleportation network in the Throne of Darkness (a Galchutt stronghold deep beneath the surface).

If you know the signet’s name and can see it, you can command it to shrink down to the size and weight of an amulet or return to its normal size. The signet doesn’t emit darkness in its amulet form.
