I think we'll get a lot of Dark Realm information in episode 13 with Gideon and possibly also with the Black Fairy's backstory in 19. And I'm still hoping that it will be something recognizable. If Gideon wants to be its savior, that means it's something besides the Black Fairy's home - there is something there worth saving.

Besides that, though, I'm guessing that after the Black Fairy is defeated/redeemed/whatever happens to her, we'll get some mention from some Dark Realm character about how "surely now happiness will return to our land!" and that's about it.
