Middle Ages

The Middle Ages were an era in human history following the Dark Ages.

At some point during the Middle Ages, the planet Strepto vanished. (TWN: Something in the Water)

Compared to the 21st century, Britain was on average three degrees colder in the Middle Ages. (K9TV: The Last Oak Tree)

Behind the scenes

 * The non-narrative source REF: Doctor Who: The Time Traveller's Almanac stated the Daleks had stolen Strepto, making it one of the 27 planets they needed to activate the reality bomb. This is contradicted by DW: The Stolen Earth, which counts 24 planets being taken from 2009 and the remaining three from other eras named by the Tenth Doctor and Donna as the Lost Moon of Poosh, Pyrovillia and Adipose 3, causing the Shadow Proclamation's map to put the planets in alignment.
