A young girl named Aqua discovers there is an alternate LOTR-esque fantasy world apart from her own(kinda like another dimension, but not quite) and she is prophesied to defeat a corrupted god.
That's all I'm going to say. It's so much more complicated than that, and it goes further than that(I'm writing like, 3 series that all follow the same overall storyline in the same world, along with side stories) so there you go. I'm not going to say much more than that since I'm planning on actually publishing it.
