THE MASTER IS NOW A DECREPIT FIGURE NEARING the end of his natural life. On the planet Terserus he mentally dominates the Time Lord Chancellor Goth, who conceals the dying renegade in the vaults beneath the Capitol on Gallifrey. Once hidden, the Master pursues a devious plan to restore his ability to regenerate, as well as to destroy his home world, the Time Lords and a hundred other planets. The plot hinges on assassinating Gallifrey’s current President and replacing him with Goth.
The Master requires a scapegoat for the President’s assassination. He also knows that the Capitol’s APC Net Matrix will warn the Time Lords of the murder. The Master scans the Doctor’s data extract (DE) and mentally intercepts the APC prediction. He then uses the Matrix and the DE information to beam the forecast of the President’s death into the Doctor’s mind.
