9th century

The 9th century was when the Doctor liked to get his milk. According to the Tenth Doctor, he went to "nice little farm" in France, at least until the milkmaid developed boils on her hands. (COMIC: Wrath of the Warrior) At some point in the century, the Second Doctor, Ben and Polly arrived in Baghdad, having been chased there by the Cat-People. (PROSE: Invasion of the Cat-People) The Library of St John the Beheaded was founded sometime this century. (PROSE: All-Consuming Fire) The Fifth Doctor and Amy visited Sudan in this century in search of the fifth segment of the Key to Time. (AUDIO: The Destroyer of Delights)

This century also saw the death of Ashildr, later known as "Lady Me", a Viking girl who was brought back to life by the Twelfth Doctor, accompanied by Clara Oswald, through a Mire medical kit, having gave her life to repel a Mire attack on her village. As the kit would never stop repairing her, Ashildr was rendered effectively immortal. (TV: The Girl Who Died) She would thus live beyond well beyond the average lifespan of a human, to at least the 21st century. (TV: The Woman Who Lived)
