Permafrosted Keystone

<Several void-touched runes flicker across the keystone's surface before dissipating one by one. As the last rune fades, so does the faint hum of power within, leaving nothing but a painfully cold sphere of dark green metal.> Although it doesn't resemble other domanaar artifacts, there was no mistaking the cold, dark magic. Perhaps Decimus in the Howling Ridge can provide you with more information.>
