Doctor uncovers Castrovalva's forged past

The Doctor pieces together subtle inconsistencies in Castrovalva’s official history while examining Shardovan’s fabricated chronicles. He reveals to Ruther and Mergrave that the town’s entire 1200-year lineage is a deliberate forgery, exposing the recursive nature of the place. When questioned about how he can be certain, he produces a hidden annotation from one of the books, though he admits even he doesn’t yet see the full picture. The discussion shifts to Shardovan as the likely architect of the deception, but the sudden noise outside distracts them as the Master’s plan inches closer to unfolding. This moment plants the seed for unraveling the town’s fragile illusions before the Zero Structure’s collapse. key_dialogue: [ DOCTOR: These volumes chronicle the rise of Castrovalva out of an alliance of warring hunters twelve hundred years ago.
