Ooh! That sounds like it would be a lot of fun to read!

(It also sounds like it would be fun to write, but my OCs are getting their culture clash well before Nirnaeth. Most of them. In most of the AUs. Possibly because I haven't come up with any named and prominent First Age non-elven OCs yet.)

Now I am even more curious about what is the Random Thing that you're wanting to read. Because collecting plot bunnies is a thing. :D
