How can Doctor Who be the last Timelord?!
Question:
How can Doctor Who be the last Timelord?
If the Timelords are a race of time-travellers..... shouldn't they be all over the past and future regardless? I don't understand the premise.
Answers:
Time Lord society was based on a strict policy of non-interference with other worlds. (They existed only to watch, never to participate)
Only in extreme cases or if they themselves were attacked did they participate in events outside of their own world.
On one rare occasion they sensed the threat that would soon be posed by the Daleks and sent the (4th) Doctor to intervene. It has been suggested by the writers of the current series that this was the first stage of the Time War that resulted in the destruction of both the Time Lord and the Dalek races.
No Time Lord who complied with the rules would ever leave Galifrey, those that did were considered Renegades
Such as
The Doctor
The Master
The Meddling Monk
The War Chief (War Lord maybe, I can't remember)
The Rani
Omega
Susan Foreman (The 1st Doctors Granddaughter, but it has never been confirmed if she was a full fledged Time Lord or just an inhabitant of Galifrey)
It is assumed that during the Time War the Daleks tracked down the (very) few renegade Time Lords that excisted and Exterminated them, apart from The Master who turned human and hid, and the Doctor who fought back and ended the war by destroying both races.
