Why was it necessary that the twelfth Phantom be a monarchist?
He wasn't. But there was this beautiful French countess who wore the Good Mark . . . .
He was fulfilling an ancient obligation to her family, as the Phantom has always done. One of her ancestors had saved a previous Phantom, so he was just returning the favor by rescuing her from the guillotine.
He wasn't fighting against the Revolution, just the Terror.
P.S. Don't worry, Demotion! I'd love to do some more historical Phantom stories myself.
