A merpony swam along, admiring the coral gardens of Aquastria, looking at the fish, admiring the corals, seeing merpony foals bounce on the sponges, and even a starfish. She continued deeper into the gardens, not knowing that something was following her.

She was still looking at the corals when she heard a tiny "KREE!" from behind her. "Huh?" she said, turning around.

What she saw was a peculiar-looking blue crab. Something was wrong with it, for starters, it seemed to lack pincers, only had six legs instead of ten, and its face was only eight eyes, almost like a spider. "Hey, little guy." the merpony said, holding a hoof out, ready to pet the spider.

"Here, I'm not going to hurt you." she said, when she got close enough, the spider jumped at her, injecting acid into her blood. A bunch of other spiders crawled out of the coral, doing the same thing. "Oh no," she said as her life slipped away.

Queen Atlantis was busy going to announce her people about an infestation that happened when a voice rang out.

"CITIZENS OF AQUASTRIA!!!" a male-sounding voice boomed.

Everyone turned their heads to see a very strange-looking being. It was a bipedal creature, with almost metallic skin as blue as the ocean. Its markings were a darker blue, its hands and feet colored the same shade. It didn't appear to have a head, rather, it had five hornlike structures that deceivingly looked like a crown. Its glowing blue aura vibrated with every syllable that is spoke.The most unnerving part was its only facial feature, a single catlike eye that gazed at them. They looked to the being's left and right to see four of those strange creatures swimming right on either side.

"I have come to kill you, for you control the tides and ocean. Since you help the ponies with their control over Earth, you and all of the merponies will DIE!!!" the being said as it, or rather he pointed a finger at them, the spiders either swam or scuttled towards the merponies and started killing them all willy-milly. Naturus pointed his finger at a nearby guard and killed him, staining the water red with blood. After killing the guard, he went inside the passage. "Time to find this thing." he said.

"NO!!!! That leads to the Sacred Coral Flute of the Sea!!! If he finds it, then he'll gain full control over the oc-" Atlantis said before a bunch of spiders piled up on her, the last thing she saw was Naturus going into the passage.

Naturus held his hand out in a karate-chop position, an energy sword came out. He used it to chop the seaweed outcroppings as he advanced deeper into the sea. He did this a couple of times before he saw a golden light. He telekineticlly pushed the seaweed away a saw what he has been looking for, it looked like a red piece of coral, but it was arranged into what looked like a flute, and decorated with shells and pebbles. "Yes!" Naturus said.

"That's it, the Sacred Coral Flute of the Sea, once I absorb its power, I'll be-"

"Don't you dare!" Naturus looked behind him and saw two merpony guards with coral spears behind him, looking like they were ready to stab him. Naturus chuckled at their attempt to scare him, he was immune to magic, he can see through the illusion spell put on their armor.

"I have to say, you are brave to go down to this place with me." Naturus said as he caught the flute in his telekinetic grasp. "You don't realize the story of this here flute. Well, your ancestors were ordinary ponies, back at that time, the ocean was as untame as it was supposed to be. So you dolts, under the command of the council, grabbed coral from the nearby reef, and crafted the flute, turning you into merponies and giving you and your ancestors control of the ocean. But, now..."

Naturus willed the flute into his body, absorbing it and its power, converting it into a non-magical energy, the same energy he has.

"since I have now absorbed it, the ocean is now free." The merponies gasped in horror as they and the surviving merponies lost their control over the ocean. "What have you done?" one of the merponies said as he looked outside. Naturus grinned smugly with a nonexistent smile, watching as the ocean turned on the merponies, fish started to refuse their command as sharks and sea serpents devoured them. One of the gaurds felt his body tingle. He and his friend looked down to see that their tails were splitting into legs, then they realized something, they can no longer breathe.

"Look at you, struggling for air, you know, that would be what I would imagine the fate of the ponies to be, struggling against nature, only to die soon after, bye!" Naturus said as he left the cave, leaving the now normal earth ponies to die.

Author's Note

So yeah, I don't know ANYTHING about Aquastria, but anyways, I haven't done a design on Queen Atlantis or the Sacred Coral Flute of the Sea yet. I'll think about the designs later, K.
