After Beatrix was elected Divine, my choice was stark: head out with the Exalted March or resign."

He pauses, then adds a little more quietly, "I think the election also made clear to me that reform for the Order was unlikely, at least in the short term. A don't know if I'd have left, with a more liberal-minded Divine in power. Or maybe I still would have eventually. But probably not right at that moment."
