After Nightmare Moon’s return and battle for the throne, Princess Celestia and her protégée, Princess Cadence, subdued the maddened alicorn and managed to imprison her. Celestia had no time to celebrate not having to re-banish her sister for another thousand years; she went into a deep study, searching for the missing key that would activate the Elements of Harmony and free Luna of the poison darkening her mind and feeding on her ancient wrath. Princess Cadence and her husband Shining Armor took over running the throne of Equestria, giving the sisters time to find a solution and reconciliation. She is a wise and fair leader, despite her youth, and the uneasy country began to settle.
 
But with Celestia so distracted and Cadence not yet trained in monitoring the ancient dungeon of Tartarus, Tirek made his escape unnoticed. He was more cautious now than in his last quest to steal Equestria’s magic: the theft of a few ponies’ magic here, the emptying of a lonely hamlet there. Rumors of a magical plague and a strange monkey-horse creature who ate magic were all Cadence and Shining Armor had to go on, and they and the Royal Service were baffled by this creature or affliction that struck and then vanished again and again. Panic began to spread through Canterlot as more and more ponies on the outskirts of the city reported their magic stolen.
 
By the time word of a magical plague and centaur sightings reached Celestia, the only pony present who would recognize the significance, it was too late. Tirek had gained enough magic to come into the open and make his attack. First Cadence and her husband and guards fell, unprepared for what they faced. With Cadence’s alicorn magic combined with the many ponies’ he had stolen, Tirek defeated Celestia in spite of her best efforts. And lastly, ignoring her spitting invectives, he drained Nightmare Moon, as well.
 
With such potent magic flowing through him, Tirek’s lust for more power grew worse than ever before. He set out to steal the magic of every pony and magical creature in Equestria - and there were none who could hope to stop him.
 

 
In the town of Featherhorn, there lived a young stallion with his parents, brother, and sister. He was a perfectly normal pony… or he would have been, were it not for the wings and horn he was born with. He got on alright - he had a few good friends and a supportive family, a love for his work and a faith that sustained him – but there were a number in the town who disapproved of him. He was the butt of many jokes and accusations, and often distrust. And the cultists who carried on in town caused trouble and made things worse for him, since he got the blame. He found it more and more tempting to stay out on the road, plying his trade and absorbing the confusion of strangers better than he could take the dislike of his own neighbors.
 
One day while the stallion was home, the town received word that a monster was coming. The monster had stolen the magic of the princesses, and now he was a giant, rampaging across the land and stealing the magic of every pony he found. He would soon be upon their town, and there was little time to flee - for who could run faster than this massive monster? Were they all doomed to lose their magic, and worse, their marks?
 
There was a small chance: a system of caves where they could hide, deep enough that the monster might not find them. But there was not enough time to get all the townsponies out, especially the sick and old; they could already hear the creature’s thundering hoofsteps on the horizon. If only they could distract it somehow, or slow it down… but who could hope to even do that much with a monster so powerful?
 
Nopony expected the young stallion, the alicorn imposter, to speak up:
 
“What if he believed there was another alicorn?”
 
The plan was dangerous. He would need help; handicapped in both flight and unicorn magic, he wouldn’t be able to fool the monster for long on his own. Few were willing - and of those who were, only a small number had the abilities that were needed. In the end, it was the stallion’s own brother and mother who helped him craft the final bits of his plan.
 
When the monster came upon the pony town, ready to further engorge himself with pony magic, the brown stallion appeared in the sky. He flew with confidence, bolstered by the carefully-directed winds of his expert flyer mother. His horn blazed with gold and silver light, bright as a star, aided by his magically gifted brother. And the monster believed the facade, and hungered only for more alicorn magic.
 
The chase lasted an hour, carefully-aimed magically bolts reflected through Sales’ horn by Pitch Black, skillful dodges aided by Pitch Forward. They had no hope of continuing the charade indefinitely, but that hour was enough; the townsponies were able to escape, hiding deep where the power-mad centaur wouldn’t find them. When at last the centaur swatted Salespitch from the sky and drained the magic from his injured body, the monster was enraged to taste such a miniscule amount. Black and Forward attempted a rescue, and were drained as well, their weakened bodies falling beside the unconscious Salespitch.
 
When the monster turned back to his initial target and found the town empty of all ponies - what’s more, he could not detect pony magic anywhere nearby - his wrath burned the town to cinders. But when he returned to find the ponies who had tricked him, in order to punish them further, their bodies had vanished.
 
Eventually, the monster left, continuing his rampage across the landscape. In a hollow of a tree, Pitch Black waited with the unconscious body of his mother and the severely injured body of his brother, the three of them blessedly undetectable now that they lacked their magic. But Black did not need his cutie mark to remember his driving purpose: to be there at the zero hour, when those he cared for needed him most.
 
The townsponies found them eventually; the father and daughter were overjoyed to find them alive. But Sales would not waken, though the best healers in the town mended his wounds. Badly injured and drained of magic, he slipped into a coma. Only alicorn-level healing magic might stand a chance of healing him, but that was lost to the monster.
 
But the town had been humbled. The one many of them had scorned the most – the pony who so hated being mistaken for something he was not – had taken up the very trait that caused him such trouble in order to give everything for the sake of those who despised him. The townsponies of Featherhorn vowed to protect him until he could be healed, and to keep away the members of his cult should they reappear to take advantage of his comatose state. And should he waken, they would treat him with the respect a hero deserved.
 
The monster still rampages. None in this group of refugees can hope to defeat him. But they have a refuge where they can stay safe until the nightmare has passed - and but for three of them, every pony and zebra has their magic. Perhaps one day, their fallen few will regain their magic, and the princesses will rise again.
 
But for now, they wait. And they guard their fallen hero.
