OP, I have a question! Are you after a younger Childermass when he first joins Mr Norrell's service and an older Mr Norrell? (I'm guesstimating Norrell to be around 10 or 15 years older than Childermass.) Because, I'd be so ready to read that! (I'd be up for reading anything ageplay related tbf.)

I'd love to hear other pairings you feel could work with ageplay too. It's got me thinking about the age ranges of the characters now... Would be interesting to work it out.
