Alpha Potter on AO3 has completed one or two of DobbyDobs’ challenges, not this one though. https://archiveofourown.org/works/26284570/chapters/63990064
I can’t believe there’s already two submissions for this challenge. I’d written out a plan myself for fun – I’ve never written a full story so it was only a plan. @Alpha Potter Do you have an editor, I’m interested in helping.
