Why These Connect
The narrative assertion
"The Master’s revelation that the Valeyard is an amalgam of the Doctor’s darker future selves catalyzes the Valeyard’s sabotage of the trial and his retreat to ‘The Fantasy Factory’. The Doctor’s understanding of this identity later enables him to strategically sign away his regenerations and force a confrontation."
