Is there an IRL historical equivalent of the Indigo Monks from the Book of Uther? The Black Monks are parallels of the Benedictines, but my knowledge of early British Christianity is pretty minimal and a few Google searches didn't turn anything up for the Indigo Monks. Mostly just curious as to whether they were inspired by a historical source or are a creation for the purposes of the game. Thanks.

As far as I can tell, they are a game construct.
But we'd need Greg to tell us where the inspiration came from. :)

Thanks Morien. It would definitely be cool to hear where Greg got the inspiration for them, but at least I can stop trying to track them down in other sources.
