A crossover of Umberto Eco's novel The Name of the Rose and the series Good Omens, based on the story of the same name by Terry Pratchett and Neil Gaiman. Crowley does not like the 14th century, Aziraphale also speaks of him without favor. Nevertheless, the anxieties of the present force them to remember the events of six centuries ago. For the angel and the demon, they are associated with a person who liked to ask strange questions. For example, did Jesus laugh? This was the Franciscan monk William of Baskerville - a mere mortal who sought knowledge. In a city engulfed by plague, three people will meet, and everyone will find something to do and a conversation to their liking. The author is not a historian, therefore he humbly asks specialists not to throw sabatons. Tags: post-canon, pre-canon, bromance, XIV century, canon character death, drama, AU, historical eras.
