Sorry if the title isn't exactly inspiring, unfortunately I haven't thought of a proper title to call this yet.

Anyway, on to idea itself. It's simple really, a Fire Emblem-inspired RP set in the MLP universe. I've had some vague ideas on how to handle character classes but those aren't set in stone yet. But the setting itself will be an alternate version of the canon universe. Liberties will be taken with the established canon in order to tell a more compelling story. Things play out normally up until Celestia is forced to banish Luna to the moon. Before this, both Celestia and Luna have used the Elements of Harmony on previous threats in the past, but this was the first and only time a pony used the Elements completely alone. This ended coming back to bite Celestia, as the experience leaves her totally drained and in a comatose-like slumber where she will remain until she is fully recovered. Her sleep is a long one, though. A hundred years passed where there was no Alicorn royalty to keep the unsteady truce between the three Pony Tribes, and now it seems like chaos is inevitable.

Notice that I never referred to the sisters as Princesses. That's because they aren't. They had become Alicorns, but the Monarchy of Equestria had not been established yet, and so they were not recognized as Princesses. That's also why I referred to the ponies as the separate tribes, because at this point in history they have not come together yet.

So in a nutshell, the RP will focus on the 100 Year period of Celestia being in her comatose state, and the political strife and conflicts that arise from that between the Unicorns, Pegasi, and Earth Ponies. I realize I'm being a bit vague on the details, but that's because I'm purposefully leaving some blanks so that I can remain open to suggestions and other contributions for how the setting can be better fleshed out.
