John Breton didn't found the Abbey. It was John CLAVERING who is credited with aiding in its creation.

John Breton is credited with keeping yhe Book of Strictures from being burned by enemy fire. This most likely occurred during the Siege of Whitecliff during which the valiant Overseer received a spear in the back for his efforts.

Rescuing the Abbey's holiest of texts is probably what got Breton's ashes put in the big boys, even though he was never a High Overseer.
