Description:  A mysterious evil is at work on Gallifrey. The President of the Time Lords has been assassinated and the Doctor caught is red-handed. An inexorable master plan has been set in motion. There can be no escape. The President of the High Council of the Time Lords is assassinated, and the Doctor, newly returned to Gallifrey, is the prime suspect. But the Doctor knows someone is framing him, and must rely on the help of the reluctant Castellan Kelner to unveil a traitor in the High Council. Ultimately, the trail leads to the dying, vengeful Master, who wishes to harness the powers of Rassilon's greatest discovery, the mythical Eye of Harmony. But to do so would mean the destruction of Gallifrey, and to prevent this, the Doctor must risk his life in the surreal landscape of the Matrix
