Well, we've never seen Beleriand, but a post apocalyptic Rhovanion might be cool shit. But what if it were the Titans instead?
Who's the raven? And can't we just have the titans flood this realm 'cause their empire blew up for some shit?
I'd rather not have a bunch of OP destroyers of world from Greek mythology that I hate be in an RP I make. I'd rather stick with something a bit more lore-accurate, like Sauron.
