Basically it's a New Lunar Republic vs Solar Empire fic but it also includes the other factions; The Crystal Empire, The Griffin Kingdom(s), The Changeling Swarm, as well as The Minotaurs, Diamond Dogs, Dragons, Zebras and Buffalo. It would also be a sequel to an imaginary Fanfic.

Here would be the Description:

Four years have past since the Equestrian races banded together and stood united agents the might of the Human Legion. Though Equestia was saved the tenuous pact between The Republic and The Empire has all but evaporated. The drums of war thunder once again.

the Alliance would play out like this:

The Republic: The New Lunar Republic, The Griffin Kingdom(s), The Changeling Swarm, The Minotaurs and Zebras.

The Empire: The Solar Empire, The Crystal Empire, Diamond Dogs, Dragons and Buffalo.

If any one can find a way to expand on it go a head and make it.
