The Pyramid at the End of the World (TV story)

 was the seventh episode of the tenth series of Doctor Who produced by BBC Wales.

Synopsis
At a war zone in Turmezistan where American, Chinese, and Russian armies are about to meet, a 5,000 year old pyramid stands. It's very strange, but one thing raises the suspicions of the Twelfth Doctor: it just appeared overnight. The aliens inside claim that humanity would die by their own hand. Soon, the Doctor, Bill and Nardole are facing an invasion the likes of which they have seen before. Before they invade, the aliens need the permission of humanity.
