Vareth is a Usable (Artifact) in Torment: Tides of Numenera.
You recognize this ring fragment. It is called Vareth, or (Wisdom, Chained), and is one half of the artifact known as the Shadow Ring. You recall that this artifact belonged to a castoff, though their identity escapes you. You remember only that the Changing God himself sundered this ring at the height of a cold rage and infused each half with mutually repellent energies. They have been separated from each other ever since. The Changing God went through immense trouble to separate these two rings. It must be possible to reunite them.
