14th century

The 14th century was not a century visited often by the Doctor and his companions.

At some point in the century, the Second Doctor, Jamie and Victoria went to Ireland. (PROSE: Screamager) At another point, according to the mysterious woman who once appeared to Wilfred Mott, a "demon" fell from the sky near a convent, only to be defeated by a man in a blue box called the "Sainted Physician". (TV: The End of Time) Towards the beginning of the century, the Ninth Doctor, Rose and Jack visited Kyoto. (TV: Bad Wolf)

Late in the century, Europeans invented wire-drawing machines. (TV: The Masque of Mandragora)

It was also among the centuries endured by Ashildr, (TV: The Woman Who Lived) a 9th century Viking girl who was rendered effectively immortal when she was brought back to life by the Twelfth Doctor through a self-repairing Mire repair kit. (TV: The Girl Who Died)

At some point in this century (roughly 300 years before 1601), a seemingly bottomless black pit was discovered in Kokorin Forest. Locals came to believe the hole to be The Mouth of Hell, after "strange lights" and "ungodly sounds" were said to have emerged from within. In order to quell the mounting hysteria, King Ottokor II had a convict lowered into the pit and tell of what he found there, in exchange for clemency. After hearing the convicts screams, "like none any man had ever heard", the King pulled him back up to find he had aged thirty years and his mind destroyed, speaking of "madness made flesh" and "creatures that ate the souls of gods", before dying. The King chose not to investigate any further, and had what would become Castle Houska built on top of it. (COMIC: Herald of Madness)
