The Alicorn War

Clarifications:

(The nation of equestria isn't the one we know from the show, in this story, it was basically just the collection of the 3 tribes after the hearths warming eve thing, but Celestia and luna never existed.)

(the alicorns are not immortal and are powerful but do have limits just so the story isn't a slaughter fest, and the technology of the humans will be like Today, but wont be just instant kills on the alicorns, the pony cannon fodder yeah, but the alicorns will be like mini bosses in video games)

(all other species are not going to be mentioned cause of the genocide the alicorns did to them)

(Alicorn empire will be at medieval tech but with magic, such as shields and magic blasts n stuff)

Backstory leading up to main story:

After the 3 pony races unified, peace was restored to the nation, and after 20 years of growth and population boom, the alicorn empire started their conquest. the alicorns were few in number, but extremely powerful though. After a few years of war the new nation of equestria is overwhelmed and enslaved to the stronger alicorns. The ponies weren't killed only because they were very similar to the alicorns in looks, and that the alicorns needed slave labor to fund their future conquests and feed the growing populations. things were just getting started for the alicorns, their king, King Gilded Crown, didn't just want to control equestria, he wanted to control the world. He 3 years after conquering equestria he declared war on the griffon kingdoms, steamrolling over the already war torn kingdoms with their superior tactics and magical abilities. Whoever did surrender was instantly executed and the land taken over by alicorns and pony slaves. in only 2 years nearly all griffons in the world are dead, the only few remaining left and scattered in nearby countries. After recovering from their minimal losses in the war, the alicorns decided to use the ponies as cannon fodder (or ballista fodder cause they didn't event cannons) to make sure any alicorn are protected by a massive army of slaves. after deciding that, they invaded the rest of the world. First the minatours due to their strength and war training, then the yaks, then the zebras, taking over the entire known world, crushing any rebellion in minutes.
