Tegan falls once more under the influence of the Mara and directs the TARDIS to the planet Manussa. There, the Federator's son Lon and his mother Tanha are preparing for a ceremony to celebrate the banishment of the Mara five hundred years earlier. The Mara takes control of Lon and uses him and Tegan to obtain from Ambril, the Director of Historical Research, the 'Great Crystal' - the large blue stone that originally brought it into being by focusing energy from the minds of the planet's one-time inhabitants. The Mara now plans to use the crystal during the ceremony to bring about its return to corporeal existence.

Enrique VIII de Inglaterra (1509-1547), casado con Catalina de Aragón, hija de los Reyes Católicos, se encapricha de Ana Bolena, una dama de la Corte, y decide casarse con ella. Pero, como el Papa no accede a concederle el divorcio, rompe con la Iglesia de Roma y crea la Iglesia Anglicana (Acta de Supremacía de 1534), convirtiéndose así en la suprema autoridad eclesiástica de Inglaterra. Años después, el rey acusa a Ana de alta traición y ordena que sea ejecutada.
