In Doctor Who series 9 the "Cloister War" was mentioned a few times (by Missy in episode 1, and the Doctor in episode 12).

When did this war happen? Was it on a big scale, and who was involved besides the Daleks, Cybermen and Weeping Angels? What were the motives to attack the cloisters on Gallifrey? And why wasn't the war focused on capturing Gallifrey itself? The cloisters are underneath the capital and hard to reach: how did the Daleks and others get there without capturing Gallifrey?

    As a Red Dwarf fan, I'm pretty sure the Cloister War is the war fought between the two sides of the Cat race when trying to settle the most eternal of debates - red hats, or blue hats? Dec 9, 2015 at 10:55

    @PaulD.Waite the thing with the time-lordy face isn't a Dalek, it's a Cloister Wraith. The only Dalek we saw was the one begging to be killed, IIRC.

1 Answer 1


Much like the Time War in the early days of the modern series, all we know about the Cloister War are bits and pieces that have been dropped so far in dialogue. No external source has given us any other information about it, and thus, anything we might say about it is purely speculative.

Thus, the only things we really know about it is that it was apparently focused on the Matrix Cloister under the Citadel of the Time Lords (aka the Capitol), that some of its combatants wound up trapped there permanently, and that during the course of it, a young and possibly somewhat deranged Time Lord who would one day call himself "The Doctor" borrowed the moon and ran off with the President's daughter, although the Shebogans' later legends insisted it was the President's wife.

Even this much is in doubt, however, since our primary source for most of it is The Doctor himself, and he's a notorious, self-admitted, liar, and thus has to be treated as an unreliable narrator.
