Tantalus Eye

The Tantalus Eye was a space-time anomaly during the Last Great Time War. It was located in the Tantalus Spiral. Moldox was located near the Eye. The Daleks harnessed energy from the Eye to create a Demat weapon capable of wiping Gallifrey from history. This plan was stopped by the War Doctor, who used Borusa's unique characteristics to harness power from the Eye and wipe all Dalek presence away from the area. (PROSE: Engines of War)
