Yes...it's an MLP fanfic...slightly. The main setting is Equestria, unlike Arracar Angels which will switch between the two worlds.

The whole idea is that Equestria is the latest incarnation of a world that has assumed multiple forms. And as such, it is not implausible that characters from other series will appear.

Enjoy.
