The Ponipocalypse came fast, many didn't even see it coming, others were careless about it, but only some were ready.
The Griffons had enough of the Equestrians; fed up with all of the love and care they portrayed this so called "Friendship" they wanted none of it.
A Griffon by the name of Kalinstien Shankovet wanted nothing of the country to the west of them.
So, he and an army of scientist created the new bacteria R2Bs5, it was a combination of Rabies, Bath salts and with a little radiation a new being was created, the Zompony, but in this case it was a griffon.
One night in the royal courters of the Canterlot palace, Celestia and Luna were having some tea, a royal guard dressed in shiny golden armor came with a message. Celestia noticed he looked worried, like he just saw an Ursa Major or a Hydra outside of the royal palace.
The Royal guard handed the note over to Celestia his hooves were shaky and clammy. He bowed and returned to guard duty. Celestia looked through the message.
From The Griffon Union
We will strike tonight, we are not giving any details on were or what were attacking with, supreme dictator Kalinstien Shankovet wants the friendship to stop. You have 1 hour to comply…
Don't get any funny ideas; we can fuck you twice as fast…DUH were griffons.
Hate,
Kalinstien Shankovet
Celestia couldn't believe what she just read, dropping the cup of tea while looking in horror at her sister. Luna said in confusion.
"What? Why did you drop your tea? What has happened sister!?"
Luna has only seen her sister in this state before, last time she raped all the ponies in Ponyville, but she new this was worse much worse.
