Anon, I think you read my mind! I am an RoL fan, and this is something I have been thinking about since I saw the JSMN TV series. It's fascinating to consider how the differing magical systems and histories could be made compatible. I actually think the two universes have more of a potential for fusion than any other fictional universes I can think of, which is pretty cool. :)

I don't want to promise anything, especially as I am still in the process of reading the JSMN novel and writing a fill for a different prompt, but if I feel inspired enough I may attempt short fill for this.
