Theory:Timeline - The Master

This page lists appearances of The Master in the order in which he experienced them. It relies on much speculation to fit semi-contradictory sources together, and should absolutely not be seen as representative of this wiki's general policy.

Limiting factors
Events after Survival are difficult to reconcile with each other as they offer contradictory accounts to what happened afterwards for the Master. Events after Doctor Who can be reconciled by having the Master reimprisoned within the Eye after the events of The Glorious Dead
