Too late! My Phantom versus the Reign of Terror story is already on sale!
In my defense, I should point out that Moonstone specifically asked for a story about the 12th Phantom, which put me squarely at the end of the 18th Century. The French Revolution was the obvious way to go--and, as far as I know, was largely unexplored territory as far as the Phantom was concerned.
(The 12th Phantom himself is pretty much unknown, having only been mentioned in one previous storyline.)
