It’s not exactly set in the same AU as S-hovel and K-night, but will feature your favorite German and French flyboy.
It’s probably not going to be a novel-length fanfic. Just a oneshot.
Basically, it would be a surprise ‘fic about Propeller Knight’s deal with the Enchantress.
And maybe it will make you cry, because I’m thinking about it and it’s making me cry.
