I'm honestly fascinated by the idea of "underground" subcultures in Arda. I wish more of these stories were written so I keep offering up challenges in hopes that they will be! :D This idea was part of the world-building for my Finrod/Celegorm SinS novella The Sovereign and the Priest as well. I'm thinking about it for my B2MeM story this year. And someday--probably years from now, but someday--I'll get to it in my Felakverse as well! :D
