Upon return to Shen, they were welcomed back to a grand triumph, though they soon became corrupted by the influence of their Rings of Power. They overthrew their father and assumed control of his throne. Ultimately they became servants of Sauron, who led them back to Mordor where they served him for many years.
When the Witch-king was defeated at Minas Morgul by Talion, and Sauron and Celebrimbor were fused together in the Flaming Eye, the sisters rose up against their masters in a new attempt to conquer Mordor. After their defeat at the hands of Eltariel, they return to serve Sauron.
