Tonight's post from the past concerns Regeneration Limits, a topic that has been close to the Hearts of some here-abouts, recently!!
Quote from 'Olton' in the 'Favourite Dr Who' thread of June 1991
In "Nightmare of Eden," the Doctor says something about timelords having 125 lives, and that he had had about 190. This clearly doesn't "jive" with other established facts, unless you want to think that he means that their lifespan is 125 times the length of a human's. That's possible, but the context that he uses it in implies 125 regenerations.
End Quote
So it would seem that Chris Chibnall was not the first to suggest that there had been many re-generations PRIOR to Hartnell (over and above the "The Brain of Morbius" confusion).
Discuss.
