The Eater of Souls

Summary
In Legends passed since time immemorial Zebra kind had often said to be weary of the stars. That within them lied an evil that would decimate the planet if left unchecked. Many had thought that the evil was the two pony princesses, ones with the strength to move the sun and the moon, this wasn't just not the case at all but rather something that a certain being wanted others to believe.

Long ago before any recorded history of ponies, a star had collided with the planet, completely reshaping and terraforming it. The area surrounding the impact would be come known as Hoofington the birth place of magic, being a central in the Zebra religion that the magic there would protect them from the stars...

Unfortunately for them but not only was this a ruse, but it was ruse by the star itself. The Star was sentient in that it would complete sustain itself on the souls of any sentient planet it visited, usually by tricking one of the planets own to be his herald of Doom, however after landing on Equus the being had found itself to be badly injured and immobile, requiring that it use its herald to feed on the souls above, this hellish abomination would go to be cause of or linked to every tragedy in the history of Equestria from then onward, staying hidden deep underneath the city that would become known as Hoofington. The Star Creature would need a massive amount of energy far beyond all the souls of the planet to free itself, scheming and pushing the planet into war.

This Eater of Souls took its time subtly manipulating the minds of the planets creatures, to where even other gods would fall to its power. finally however during the pinnacle of the Pony Zebra war it had started, the Ponies side had created a weapon, one that had the power to set the creature free, Project Horizons. However before the weapon could be used, The Last Pre-Apocalyptic Day had come. Not wanting such a powerful weapon to fall into the wrong hands, the ponies sealed the arming codes into a program called EC-1101, encrypting it so that it could only be opened or used by the Mane Six or a decedent of, and attempted to send it to the closest candidate for that, nearby, the closest nearby was...Stable 99.

And so the creature spent the next 200 years looking for EC-1101, manipulating some of the biggest bads in the entire wasteland just to find where it had went, 200 years later, it found the code in a stable. It had its subordinates trick the stables head into a false sense of confidence before raiding the unarmed stable, but something did not go as the creature planned. Its forces were pushed back enough to allow a mare and buck to escape, with EC-1101 nowhere to be found.

It was then the creature learnt 2 things, that Blackjack, the current holder of EC-1101. was a descendant of a ministry mare, having complete access to EC-1101 and its contents. Secondly Blackjack was no pushover and was making friends in high places. Even when Blackjack had been crippled, poisoned, and sexually abused, she refused to give up her will to fight on. It was at this point that the Eater informed his heralds that she must be dealt with directly and swiftly. while fooling them of course that it would help the "greater good" or "ascend them into godhood".

4 collective and independent armies, Sanguines Mutants, Dawns Harbingers, The Mad AI Cognitum, and The Legate Zebra tribe all collectively attacked or threatened Blackjacks life with small wars for nearly 4 months at a time. However despite all that, having her body swapped twice, living with Luna and the Living AI in her new body, Blackjack rode on to the final battle.
