The Promised Land was a place that the Half-Face Man said he was trying to get to, but one whose existence was denied by the Twelfth Doctor. When the Half-Face Man appeared to die after having been impaled upon the spire of Big Ben, he was — by means unknown — transported to a lush, garden that Missy called "the promised land" and "paradise". (TV: Deep Breath) Later — as from the Doctor's perspective — a soldier from the Aristotle appeared to die within the body of a Dalek and then was transported to an elegant tea room, where she, too, encountered Missy. (TV: Into the Dalek) Later still, the Doctor discovered that a ship of robots that had crashed in Nottingham of about 1190 had a programmed destination of "the promised land". (TV: Robot of Sherwood)
