Act 1

The Doctor, Adric, and Tremas begin this segment imprisoned, closely guarded under Consul Kassia's orders. Kassia, deeply influenced by the mysterious Melkur, solidifies her power, condemning the prisoners as traitors and positioning herself to become the new Keeper Nominate. Melkur, meanwhile, explicitly instructs Kassia to eliminate the Doctor, recognizing him as a significant threat to his plans. Nyssa, Tremas's daughter, emerges as a pivotal ally; she covertly retrieves a specialized rod from her father's quarters, uses it to incapacitate Proctor Neman and Fosters, and orchestrates the escape of the Doctor's group. With their newfound freedom, the Doctor and Tremas strategize to prevent Melkur from accessing the Source, compelling Tremas to reveal the sacred blueprints of the Source manipulator. Kassia, now officially appointed Keeper Nominate, orders the prisoners' deaths, but then cunningly withdraws guards from the grove, anticipating the Doctor's group will attempt to reach the TARDIS there. The narrative escalates as the Keeper of Traken's life force wanes, triggering a violent storm that disrupts the Fosters' ambush in the grove. Amidst the chaos, Kassia completes the succession ritual in the Sanctum, claiming the Keepership. Simultaneously, Melkur reveals his true identity as the Master, successfully seizing control of the Source, marking a significant victory for the antagonist and a dire turning point for Traken.
