St Luke's University (Shadow World)

St Luke's University existed as a virtual construct in one world created by the Monks, so that they could plan the perfect invasion of Earth.

The Twelfth Doctor was in his lecture hall at the university when the Pope arrived. After some initial confusion caused by his partial blindness, even with the Sonic sunglasses assistance, Nardole helped him understand they desired for him to read the Veritas, a document where anyone who read it killed themselves.
