A prophecy among the Sarn speaks of a visitor destined to assist them, a role the Master eagerly embraces. This development provides Timanov, the religious leader of Sarn, with the unyielding backing he has long desired in his mission to purge the unfaithful from their ranks. Meanwhile, Turlough’s hidden history becomes entangled with these events, and the potential revelation of his past poses a serious risk to the Doctor’s relationships with those around him.
