Brin Maxen was Chief Librarian of the Storm Wardens during the Nemesis Incident. After being crippled in body, he recited his account of the event to his disciples, which would later be known as the Liber Tempest. It was said that he held his own death at bay for twelve years while the account was transcribed. Differing versions of his account would be found after his death, nearly leading to a schism within the Chapter. Nearly a century later, one version would be declared the official record. It is the only sanctioned record of that time.
