>>42357294Was gonna actually write about that but tempered my autism for the sake of all anons.
My headcanon is that crystal empire was likely Fluttervalley in its early days of the G1 era. Once the fall of tambelon happens, the flutterponies are living with remnants of early pony society. Flutterponies grow low on food, chrysalis- a flutter pony- becomes the first real changeling. The flutterponies under her sway grow corrupted, but they dont become true changelings for many generations.
The flutterponies (now changelings & early breezies) migrate out once the corrupted flutterponies drain the majority of the normal pony citizens of love. The ponies who survive prior to the migration evolve to become "crystal ponies" - their crystal coats are a faux chitin that were meant to help them blend in with younger flutterponies who hadnt matured their wings yet.
The breezies migrate to find something new, the changelings to look for new food sources. The crystal ponies take over Fluttervalley and rename it the Crystal Empire. The crystal empire follows a similar plot as the comics with some differences- King Sombra and the shadow ponies are another species trying to install their own version of tambelon. King sombra enslaved the crystal ponies and used their rich magic inherited from the flutterponies of yore and their current evolution, to attempt to conquer the world. Crystal ponies already had a concept similar to "juche" of north Korea due to their experience from the flutter-changelings. Sombra just took advantage of this and promised he'd remake the world for crystal ponies.
While extending his armies outwards, he keeps the heart of his would be empire, the crystal kingdom, isolated. Sombra becomes megalomaniacal and convinced he will be the savior of the shadow ponies and the one to make a new world. Crystal ponies have their worst nightmares fed in while he abuses them on a social level.
His reign lasts several years and does not stop until Celestia and Luna attempt to kill him. Which then launches the Crystal Kingdom into a total isolationist phase. Partially of their own will, partially on the will of Sombra.
Cadence is made the ruler as a show of symbolic power- yet again showing the will of harmony triumphant over the ways of the old world.
