From https://www.bibliotecapleyades.net/hercolobus/kolbrin_09.htm: "There’s no record of the existence of this work, known generally as the Kolbrin, before the 1990s, when the 'Culdian Celestial Age Trust' produced an annotated version for purposes of private study. The CCAT were a group dedicated to carrying on the work of the Culdee Church as the original church of Britain." Yet, there is some evidence that Kolbrin is a real record of sorts.
