"The Haunting of Saint Carta's Monastery was the start of the First Ghostly War, this is a threat to the Christian World!"
Jonathan Dragan Bismarck XVII
"The Demon in your painting real"
—Lorraine Warren[[src]]

Although not associated with Chawosauria, nor it was associated with the First Ghostly War, the Demonic Haunting of St. Carta's Monastery is considered to be a key part or the beginning of the First Ghostly War that began in the early 1940s. The Monastery was haunted by a demon called Valac (also spelled Valak).

This haunting is associated with the Conjuring Universe, most prominently the 2018 horror film, The Nun, and not associated with Chawosaurian History or anywhere in the Chawosauria Universe.
