The Draconian Empire have declare war on Equestria, tired of the treaty that forcefully pacified them to not eat their neighbors, and its creator the regent of the sun.
The dragons live on the largest gem deposit the world has to offer, it was their main food source. It would only be so long before their gem mines would run dry, and the time has come to revoke this treaty.The elder dragons foresaw this and setup a secret project in motion to over throw the regent of the sun.
Equestria thrown into war against the Draconian Empire, for the dragons have invaded breaking their treaty, snatching ponies, and destroying the bordering towns. Celestia knew the mines would deplete sooner or later, but now is to soon.
-Dragons are the largest threat to Equestria. They are fierce large flying reptiles, and the majority are resistant to magic than any creature known, some would go as far as being immune. The only downside would be the higher the tolerance, the less magic capable they were, so there isn't many draconian mages.But there is an exception to that, the a minority special breed of sub species aren't affected by the downside of their cousins,and they are worthy foes. Her intelligence told her that this special race are being breed more closely after the Draconian war, this increased her worries over the centuries. She was sure she had a few centuries left to finish her project to eliminate this threat of war, but faith is faith.-Celestia thought, as she dons a specially made armor to combat this new threat.
Solar Flare is to Celestia, as like Nightmare is to Luna. Nightmare would be a more on the stealth attacks from the shadows, meaning she would wear light armor. Solar flare would be a close quarter fighter, wearing heavy armor. Though being goddess, and larger than life wings; I don't think she will have a problem with the armor being heavy. I also depict Solar Flare as being literally blinding white in contrast to Nightmare being pitch black, so don't look directly at her or you'll go blind.
