The lands of Equestria are always filled with magic of all varieties, ready for the benefit of everypony to live in peace and harmony.
But, some exist who vie not for the happiness of others but for their own gain.
The terrifying and majestic creature flies over the landscape, her wings buzzing with insectile glee over the volcanic region. She lands upon one of the many tall rocky outcroppings. She smiles as she scans over the smokey stacks, her horn blowing the smoke away to reveal the fiery village beneath.
“Ah yes, the village of the emberites, one of the four species of magical power, hidden and waiting for someone to rule over them. Of course, they would require someone as great as I, Queen Chrysalis, to make them their leader. It is but a simple tactic to take over their town. Their feeble, fiery minds cannot comprehend what wonder they shall do as my new army! Mwahahaha!”
She hops down from her perch, the changeling magic swirling around her. A moment later, the being that flies out of the sky is that of burning radiance and elegance. She trots up along the town square, all to the sight of astonished emberites.
“Oh, what horrid things,” she growls, “perpetually on fire, yet never burning? How do they manage such an existence? No matter. They are pony enough to fulfill my needs, and once they come to love me, I shall feast on that love as the queen that I am!”
The town of emberites surrounds the new arrival with her flaming mane and her bright body. She swishes her tail and trots along in the square, speaking up. “Emberites—for too long have your people been subjugated to a purposeless existence. You’ve been walled off from the world beyond, unable to spread your love to all the other elements. But for no longer, for I, Queen Inferno, shall grant you the satisfaction of fanning your flames beyond this little dome to the lands beyond. Everypony shall know about you and the fires you love to share with them all!”
She raises her front hooves to enjoy the ponies' adoration, but the emberites all look at each other, muttering and murmuring.
One of the emberites steps up, her head held high, her snout pointing upwards. “I’m sorry, miss, but we recognize no queen here. Our way is our own, and we’re happy burning in the caldera of our birthplace.”
“Oh, and you speak for all of your fellow villagers?” Chrysalis says, leaning in, a sneer spreading across her face.
“I do, as has my mother before her and her mother before her.”
“Very well, then.”
With a flash of ghastly green light, Chrysalis zaps the speaker, binding her and making her collapse upon the floor, muzzled by the changeling magic into silence.
The attack drops the changeling’s disguise, showing her off in insectile glory.
“Does anyone else deign it necessary to go against my will? Does anyone challenge me?”
There is silence among the emberites, many looking to their bound speaker, and others shaking at the presence of Chrysalis.”
“Very good,” she says, turning and blasting one of the buildings with her horn. It crumbles to dust before her. “Now, tell me where you have hidden the secret power of your flame, or I shall do the same to the rest of your homes!”
There is a clamor among the emberites, and many of them rush around. Chrysalis zips up into the air, throwing back her head and laughing. “Yes, that’s it, swarm in fear! It may not be as nourishing as love, but it is quite a delicious junk food! Let it nourish me and my changelings forever, hahahaha!”
“No!”
Chrysalis narrows her eyes, scanning the panicking public. There upon a rooftop is an emberite, slightly smaller than the speaker but with cheeks puffed and hooves dug into place.
Chrysalis zips down to hover before her, chuckling to herself through her sharp teeth. “Oh, do you dare to defy me now that all your fellows are panicking? Who do you think you are to stand up against me?”
The emberite stares at Chrysalis, her eyes fiery and focused, but her lips trembling.
“That’s what I thought,” Chrysalis says, spinning around, standing with her haunches turned toward the emberite.
“Now, I shall cease attacking your little village if you all just bow down to me!”
As she proclaims to the people, the emberite who would challenged her remains where she is, seething with the knowledge she can’t do anything.
Warmth spreads along the changeling’s cheeks, even as Chrysalis spews out hot air to the people around her. It takes a moment before she sniffs the air, looking about this way in that.
“What in the world…? What’s that smell? It… it… h-hey!”
Finally, the heat of the emberite being so close to the changeling’s butt has radiated enough to leave her with a aching burning throbbing pain that makes her jump! “Ow ow owwww!”
Chrysalis leaps up into the air, fluttering haphazardly before crashing into the ground, rubbing her butt and groaning. It throbs and stings, the flesh reddened and warm by the ambient heat.
The fiery pony leaps off the roof, staring at the downed changeling and snorting. “Are you ready to leave us alone now, you evil, evil mare?”
Chrysalis’s eyes glow green as she snaps at the pony. “Oh, you’ve asked for it! Prepare to feel my wrath!”
The emberite pony stands before the fuming Queen Chrysalis, standing her ground with her horn leveled to the changeling matriarch. “Y-you can’t hurt our people anymore. I won’t let you!”
“Oh, you think you’re somepony special, do you?” Chrysalis asks, snickering through her teeth. “Well, let me tell you something. I am the queen of the changelings, and my magic is superior to any trick you or your fellows would ever be able to use against me.”
“You asked for it,” snorts the emberite, charging forward towards the flying fae creature.
Chrysalis flutters up high, boasting as the emberite rushes past her. “You silly little filly! None of you are gifted with the power of flight! Did you think your grandiose display would be enough to make me quiver in fear? Oooh, you must be fuming mad!
“I am,” says the emberite before her horn glows. “But you’re going to be hopping soon, you fake queen!”
Chrysalis snarls, swooping close to the fiery pony kicking her legs defiantly through the air. “Of all the impudence! I shall consume all of your emotions until you are nothing but a husk! A smoldering ruin of your former self, and I shall feast upon the magic that makes you happy and in love and fear, and with that power, I shall conquer all of Equestiria!”
As the villainess monologues, the emberite pony’s horn glows, and an ember of flame shisping up from one of the buildings becomes a ball. It dances around while the evil queen spills her diabolical schemes. And just as she’s about to finish her final words, the fire turns into the shape of a mouth, and the fiery teeth gnash onto the queen’s butt and squeeze!
“YEEEEOOOOCH!” Chrysalis wails, buzzing around the village, a smoke trail following her wherever she goes. The once fearful citizens begin to cheer and chortle at her pain, waving their hooves in the air and chanting in delight for their hero.
Chrysalis falls to the ground, eating dirt with her butt held high, tooth marks indenting and crispy as the rest glows like coal. She spits out the mud and groans, stumbling to her feet. “Of all the indignities. How dare you, ah!”
A whip of fire forms and slaps her on the hindquarters again, stinging her opposite cheek with a red burn next to the bite-mark burning on her other cheek. She leaps up, yelping and skittering around. “Yow, yow, yooooow!” before she lands on all fours, her legs buckling. “T-this cannot continue! I shall destroy you and your-yeoooch!”
Another slap, this time by some of the ambient fire that litters the ground leaping up and spanking her like little rockets before landing down on the ground. Only then do they leap up again, juggling and playing her butt like a drum, and they are the sticks leaving her stinging and red.
	“Yow, ow, wow yow-ow -wow! Stop this hot stuff nooowww ow owww!”
” Her cries wail out to the beat of the little sprites, making her scream a tune as she flails about through the air, giving the emberite something to dance to as she controls the fires.
The changeling begins to gallop away, but she’s chased by the one who would stand up against her, forming different shapes out of the fire, smacking her repeatedly in a sign of defiance against her. This continues until a flaming pony forms behind her and spins around, kicking her rear with its hind legs, leaving bright-white unshod hoofprints on her heinie and sending her tumbling down a hill at the city's edge.
When she finally stops rolling, Chrysalis lands on her butt, pressing against the heated ground. It burns momentarily, searing her hide before she leaps up again, flying high into the air, moving fast enough for the wind to sting her flesh. “Ow ow oowwwiee!”
“Owie?” Boasts the hero of the village. “That’s not very much the sound a queen makes, is it?”
The changeling snaps towards the hero, tears welling up in her eyes as she fights against the stinging, roaring burn that travels from her butt up to her spine. “H-how dare you tease me y-you fillie? I am the queen of the changelings and, yow!
The pony hops up high, flames sending her flying up, tackling the queen. As the two fall down, Chrysalis lands with her butt up in the air, and the emberite pony falls right on top of her, most of her weight upon Chrysalis’s butt.
“Aaaaauauuuuuuuuuuughhhh!” She shifts underneath as the skin seers and smoke rises from her, her butt getting bright red as she reaches vainly to escape.
“You aren’t getting away that easily. I would have let you go if you had just left us alone!”
“Please, I… I yield, just make the burning stop!”
“Not until one last thing!” the emberite says, hopping off of the queen and brandishing her horn.
“Please, ah, pull it away. S-stop stop! Please! Aaah faaaaah haaaa!”
 The emberite’s final slap with her horn pokes straight at the center of the changeling’s butt, leaving a bright white spot on Chrysalis, which throbs and stings much hotter than the rest of the burning red behind.
“Now, when someone looks upon your royal rear, they’ll know you messed with us and were punished. Now go.”
HIssing, Chrysalis stumbles to her feet, her legs wobbling. “T… that won’t… s-stop me. You hear!” she snarls. “I’ll get you back for this, you blasted fire ponies. You’ll see. Maybe I’ll find the water ponies and take them over. Then they’ll flood you until you’re nothing but hot air!”
“You’re the only hot air around here!” boasts the hero, smirking as she gives a big wink.
A smaller emberite leaps from the shadows, jumping up under Chryalis’s butt, and letting her mane roast the changeling’s abused ass!
She catches aflame, and she yelps and leaps up as the hot ass burns so hard as to smoke. She screams and runs around, hopping and kicking, leaving behind a trail of smoke as she rushes from the others and clops away, her back legs trembling as the pain burns through her. 
The other ponies of the village clamber around their champion, lifting her and praising her, leaving the changeling queen alone.
