Unfathomable
-Chapter Eight-

Something was wrong. In his grogginess, it was hard to say what it was, but something was definitely not right. The first sense that returned to Sora was not touch, vision, hearing or even smell; it was topographical orientation. He felt that he was pointing in the wrong direction, as if he was standing on his head. When he opened his eyes, it was to find that he was staring into a great nothingness.

Where am I?

He took a deep breath and felt pressure against his chest and heaviness around his mouth and throat. Wait. This isn’t air. This is…

Panic robbed Sora of all sense of rational thought. Water. He was in the water! He thrashed in an attempt to get to the surface. Air! I have to get air! His arms kept hitting something and his legs felt stuck together. It was a scene from his worst nightmare; one where he hopelessly drowned in a pit of darkness.

“Stop it!” commanded a voice. Sora’s wrists were grasped and his legs were tied. He grew even more frantic as water invaded his lungs to the brim. Someone was holding him down. There was no way he was going to survive. He was going to die!

Riku managed to wrestle the flailing Sora into submission. He wedged the Trident between their bodies, which were now wound together into a tight knot of tails. The prince forced Sora’s hands behind his back by the wrists. “Stop it,” he repeated. “You don’t have to breathe anymore. You’re like me now.”

Sora’s eyes were dilated and his expression full of abject fear as he panted uselessly in the water, his gills flaring with every huff. The dimly lit vision of Riku staring down at him slowly brought him out of his panic. His attempt at mouth breathing slowed, as well as the desperate fluttering of his gills. “Riku?” he tried to whisper, but he couldn’t hear his own voice. Instead, a lone sound came from somewhere deep in his chest, as uncertain and confused as he was.

“You can sing,” clicked Riku with no small measure of relief. He released Sora’s tail and one of his wrists, but kept the other secure in his grasp. “Can you understand me now?”

“I hear you,” answered Sora uncertainly. “But I can’t hear me. What’s wrong with my voice? Why do I sound like this?”

Riku chuckled, and the noise thrummed richly in the water. He swept a hand down Sora’s back, touching the dorsal fin that was there and traveling lower behind his mate’s new tail. It was forced to curve upwards, nearly folding Sora in double so that he could look at his own blue scales. “I already told you, you’re one of us now. You’re a mer.”

Sora felt an incredible nausea when his back simply bent in a way it was never meant to, allowing his lower body to rise up in plain view. However, instead of legs, a sleek, blue tail came into his field of view. The panic that had previously been under his control began to rise again. “This.. this is impossible. I’m not a fish, I’m human!”

“Forget about being human. In this form, we can be together,” sang Riku earnestly. “You’ll live with me in the palace. We’ll never have to be apart ever again. You will be my chosen.”

“Did you do this to me?” demanded Sora, his notes growing shrill. “Did you make me into this just so you could keep me?”

“You were going to die,” clicked Riku harshly. “Either you were going to be mine or you were going to be dead. I figured that you didn’t want to be dead, so I made the choice for you.”

“Can’t you change me back?" Sora’s arms were the only part of his body that felt as if it was still under his control. He used them to grasp Riku in pleading. "Please, change me back!”

“No,” sang Riku. His tone grew dark at the fact that Sora wasn’t responding favorably to the part about them finally being together. “If I did, you’ll die.”

Sora automatically held his stomach. He remembered the excruciating pain that he was recently in. The relief that he should have felt was shadowed by the news he was hearing. “Is it because I was too sick?”

“You weren’t sick,” sang Riku in low notes. The Trident was steadied in his free hand, and he resumed swimming with Sora in tow. Around them the water was lit by the soft glow of the mystical weapon. “You are carrying my seed.”

Sora’s expression turned fearful as Riku pulled him deeper into the dark ocean. The water pressure should have crushed him, but his light, too flexible body resisted it. “What does that mean?”

“You are going to carry my son,” sang Riku proudly. “The next king of Atlantica.”

Sora stared at Riku. He wanted to say that this was some kind of sick joke or that he was dreaming. None of this could be real. However, he knew deep down that he was being dragged to a new reality that he could not escape from. One where he may never see his family, friends, or Kairi ever again. In this new world, his body was permanently deformed, and if what Riku was saying was to be believed, then he was..

It was more than he could bear. Dying was probably better than having to live like a monster from the ocean. This had to be punishment for what he did. He broke the laws of nature, and now he was transformed because of it. Sora covered his face in shame. He did this to himself, all because he was too weak to face being alone.

“Get it together,” clicked Riku with annoyance at his mate’s behavior. His human was acting as if living in the lap of luxury in an underwater palace was a burden. Sora should have been rejoicing at the fact that his life was saved and that they would be together. What more could he possibly want?

In time, he would make Sora forsake his life as an air breather. Then he would never desire to leave the water ever again.

{{———————————————–}}

“What is going on?” sang Aqua in low notes. She was swimming alongside Terra through the darkened city of Atlantica. There were frightened mers hidden amongst their cave-like homes and sentries patrolled the waters with spears and swords in hand. Everyone carried bowls of volcanic glass filled with bioluminescent creatures in an effort to light their way. They glowed like feeble stars struggling to survive the unwanted night.

“Nothing good,” answered Terra. Upon receiving an urgent summons from King Triton’s personal messenger, they made haste to answer. It was clear that things were very bad when they entered the neighboring kingdom and saw the state it was in. “Stay close. It’s easy to get ambushed under these conditions.”

“Why would King Triton take all the light away?” mused Aqua. “Is he trying to start a riot among his own people?”

“We’ll ask him ourselves,” sang Terra. He took one of Aqua’s hands and increased the speed of his swim. If it weren’t for Nemo’s guidance, it would have been difficult to reach their destination due to the absence of light. The clown fish directed their movements until they reached the nearly invisible entrance of the palace. There, they were greeted by the guards, who led the way to the interior chambers with their glowing bowls.

The king was seated on his throne, which was temporarily lit with smears of bioluminescent algae. Sebastian was crawling back and forth on the back of the seat with a nervous expression on his face. Upon the arrival of the guests, they both perked up and looked at Aqua with an unnerving intensity.

The mermaid was taken aback by their stares, but she hid it by dipping into a bow. Terra did the same beside her. “I am here as requested, sire,” she clicked respectfully.

“Thank you for your timely arrival, despite the circumstances,” answered the king. “I have asked you here because I have an important question.”

“I will answer anything you wish,” returned Aqua, her notes now filling with curiosity.

The king looked at Sebastian, and the crab exchanged the glance. Instead of asking the question, they fidgeted uncomfortably.

“Your majesty?” inquired Terra. “Does this have anything to do with the current state of your kingdom?”

“I’m afraid that the answer is yes,” sang Triton. He began stroking his beard. “Lady Aqua, have you ever. Did you. With my son.”

“I don’t understand. What is it that you are asking me?” pressed Aqua.

Sebastian remained silent throughout the whole debacle, until he couldn’t take it anymore. He rubbed his claws over his face hard enough to stretch his cheeks downwards, and then he exploded. “Did you o’ did you nod ‘ave relashions wid da prince! Da trident 'is saying dat Prince Riku has an heir an dat bratty prince has flitted off wid Atlantica’s powah—”

“Enough!” boomed Triton, which immediately silenced the crab with an ‘eep.’ He glared his gills, and then he sang in the nicest tone possible. “So did you?”

Aqua’s mouth hung open at the audacity of the question. She turned to look at Terra, who was now staring at her with an intent expression. “No!” she answered in a shrill note. “Of course not! Why would you even think that I would do such a thing?”

Terra didn’t respond to her, which made Aqua even more taken aback by the situation she suddenly found herself thrust into.

When the awkward silence continued, she asked, “What about the Trident? If I was carrying the heir to this realm, wouldn’t it respond to me?”

“Unfortunately, the Trident is not currently available,” sang the king in resigned notes.

“I see now,” clicked Terra. After silently putting together the pieces of what Sebastian and the king said, he was finally getting the picture. "Prince Riku has an heir, and he has taken the Trident. That’s why your kingdom is in darkness. What does he intend to do with it?“

"I assumed that he would take it to the one that is carrying his first born,” clicked Triton. “I hoped that it was Lady Aqua, but perhaps I was wrong.”

A cold, sinking feeling went from the pit of Aqua’s stomach to the ends of her tail. Her thoughts flashed to the human boy that Riku was cavorting with, and she hoped against hope that what she was thinking was not about to come to pass.

“Your majesty,” sang Terra. “Your kingdom is vulnerable in its current state. Allow me to send word to King Eraqus for reinforcements.”

“And imply that there is an alliance with Lumina?” scoffed Triton. “Absolutely not.”

“The orcas could chose this moment to strike,” argued Terra. “They will invade Atlantica while it is without the Trident’s power. What if your son doesn’t come back in time?”

“He will return,” sang Triton in deep, booming notes. “Whatever it is that my boy has gotten himself into, he will return with the Trident in hand. I have faith.”

Terra hoped that faith wasn’t misplaced in the rude, headstrong prince.

{{———————————————–}}

They were almost there. It was risky to take the Trident away from Atlantica, but Riku was desperate enough to try anything. Now he was rushing back to the city to return the weapon to its rightful place, but he could only go so fast with Sora’s dead weight dragging behind him. With his mission complete, the gravity of what was going to happen when he returned to the palace was starting to press in on him.

“The catch of the day looks like it barely made it off the hook,” sang a familiar voice.

Riku came to a dead halt when he heard Braig. Sora was hugged close to his body and the Trident was slanted in front of him in a protective stance. “I’m really getting tired of you sneaking up on me,” he clicked.

Braig emerged from the darkness and entered the pool of light that was cast by the Trident. He circled around Riku in an attempt to get a good look at Sora, but the prince pivoted to prevent him from getting too close. “Damn, that is one ugly mer, and I’m just looking at him with one eye,” he commented.

“Shut up,” hissed Riku.

“Seriously, he looks like a scavenger fish. Like, couldn’t you have given him a more interesting tail?” sang Braig. He scratched the side of his cheek as he looked at Sora as if he was some sort of abomination.

Riku hadn’t taken the time to get a close look at the form his human took. Yes, he was a mer, but he lacked the majestic dorsal wings, the gradient colors or the interesting patterns that marked the bloodlines of the kingdoms. Instead, he had drab, slate blue scales and simple dorsal and tail fins. He looked like one of the nomadic mers that existed without any liege; scavengers that lived off the wild waters in uncivilized packs.

It was annoying that Sora didn’t look like a mer that was fit to mate a prince, but there was no time to worry about that now. “He’s fine the way he is,” clicked the prince. “Now out of my way.”

“I wouldn’t go back if I were you,” advised Braig. “You really think the mers in your kingdom are going to accept him? They’ll treat him like a hermit crab’s old shell, and that’s before they figure out that he’s actually human. You should bring him to Noctis instead. We just loooove humans. You can live in the palace, mate him to your heart’s content, make lots of little younglings. As long as you have that Trident, the king can’t stop you.”

Riku hesitated. It was true that if he went to Noctis, he would be treated differently. He looked at Sora, who was covering his face as if that would somehow hide him from the world. Although it was now happening less and less, his mate’s body glowed faintly as it resonated with the pulse of power from the Trident; a stark reminder that the future heir of Atlantica was alive and growing.

It was in that moment that Riku realized that he was not just making a decision for himself, but for Sora and the unborn son that he would have. He barely cared about the people in his kingdom; they were an unwanted burden that was thrust upon him at birth. However, the responsibility that he had now came from his own choosing, and for that reason, it actually mattered.

“Thanks, but no thanks,” Riku clicked after a long moment. “I’m not afraid of my father." He resumed swimming in the direction of Atlantica.

"Consider it an unlimited time offer,” sang Braig at the retreating prince. He scowled once the mer’s light faded into the distance. “Why don’t we just take the Trident now while he’s alone?”

“Because it’s not just a kingdom that we are going to conquer. We are going to rule the entire ocean,” sang Xehanort from the comfort of his palace. As always, he was watching and listening to the goings on through his proxy. “For that, we will require the power of the Trident, which can only be used by those who will succeed the throne.”

“So we convince the brat to work for us and turn him against his old man,” clicked Braig. “Yeah yeah, I get that, but it ain’t working.”

Xehanort’s lips stretched into a thin smile. “What made you believe that it was the prince that needed convincing?”

“Ooooo I get it,” sang Braig with a smirk. “I wasn’t really delivering a message to the royalty.”

No. That message was meant for someone who was a lot more desperate and weak; someone who had very little to lose at this point. It was meant for a very ugly mer.

{{———————————————–}}

Notes of relief echoed through the water when light returned to the stones of Atlantica. As the prince swam through the city, the Trident set the structured rocks and caves aglow. The mers clapped as Riku returned to the palace, which burst into a fountain of luminescence when he passed through its main doors.

The sentries bowed as the prince went to the throne room. His grip on Sora’s wrist tightened as he beheld his father, Sebastian, Aqua and Terra already waiting expectantly for his arrival. When the inhabitants of Lumina saw who he was bringing, their faces turned to shock. Sebastian looked confused, and Triton appeared as if he could tear a new gorge into the ocean with the thunderous expression on his face.

“What is that?” hissed the king sharply. Triton rose from his throne and pointed at Sora.

Riku came to a stop and drew his human possessively to his body. “My chosen,” he sang with pride.

“Don’t be ridiculous, that is not a mer,” thundered Triton. “You can’t fool me, boy. That creature is obviously not of this realm.”

Riku had hoped that he could keep the truth of what Sora was a secret, but it was quickly becoming apparent that his father could easily see through the magic. There were so many things about the Trident that he did not yet understand, and he was realizing it now. “He’s human,” he clicked.

Sebastian gasped, and Triton’s expression turned to horror. “You know the rules. You are never to go to the surface,” he sang in stern notes.

“As a future ruler of this kingdom, if I want to break that rule, I can,” clicked Riku.

The king was shocked by Riku’s impudence. All of his ideas about the type of son that he had were quickly starting to crumble. “You have no idea of the consequences. There are reasons why contact between human and mer are strictly forbidden. You can not fathom what you may have started.”

“I don’t care." The prince curled his claws into Sora’s scales. "He’s mine and I’m keeping him.”

“Keep him? As if he was some kind of pet? Look at him. Look at what you’ve done to him." The king gestured to the cowering human. "That pathetic form is a reflection of what he is. The Trident’s power reveals one true self no matter what shape they take. You have shamed that human. If you have any ounce of compassion for him, you will return him and forget him.”

“He can never go back,” sang Riku in turbulent notes of defiance and anger. He pointed the Trident at Sora’s face, causing the human to turn away from its dangerous tines. Immediately, his mate’s body began to glow in response to the weapon’s proximity. “He is carrying a son of Atlantica.”

A shocked silence filled the throne room. The knowledge of what Riku had done was so abhorrent that no one knew what to say. Aqua held onto Terra’s arm tightly as if she was clinging to the last sane thing under the ocean. They couldn’t interfere in this family matter, and frankly they shouldn’t have been witnessing it. She wished that they were somewhere far away instead of having to endure this severely uncomfortable situation.

“No,” sang Triton, the notes lowered in sheer dismay. “Why would you do it? What could this human give you that was not at your fins from the moment that you were born?”

“A choice,” answered Riku. He pulled Sora into his embrace, ignoring the feeble notes the human made as he was crushed into his chest.

“You have tested me long enough, Riku,” clicked Triton. “I have tried to be patient and understanding, but you have crossed where no mer has the right. From this day forth, you will no longer have my support. Since you believe that you are merman enough to make your own choices, then you can fetch your own meals, carve your own cave and work with your own claws like every other decent fish in this kingdom.”

“Fine,” answered Riku defiantly.

“Now return the Trident,” sang Triton. “You are a hundred cycles too early to wield it, and you have already caused enough trouble to our people.”

“This is staying with me,” retorted Riku in flat notes. “I am not going to give you the chance to turn Sora back into a human.”

“You’d rather leave our people in the darkness for the sake of your foolishness?” seethed Triton.

“I’ll stay in Atlantica,” sang Riku. “Everyone will have their light, and I’ll have what I want.”

“So be it,” agreed the king.

Aqua made a strangled sound. She couldn’t believe that Triton was going to allow such a dangerous weapon to remain in Riku’s hands. Terra jabbed her with his elbow to remind her that she had to stay silent.

Riku chose that moment to rudely leave the throne room without so much as a bow. Once again, Sora was dragged alongside of him by the wrist.

“You may also leave,” the king said to Aqua and Terra. “I apologize for dragging you into this, and I will also appreciate you keeping this matter quiet.”

The mers from Lumina bowed with murmured notes of “As you wish” before swimming out of the throne room at a brisk pace.

Once everyone left, Triton floated onto his throne and held his head in his hands. Sebastian wore a disheartened expression on his face, and after a few moments, he wheeled his claws and legs to swim up to the king’s shoulder. “Dere dere yo’ majesty,” he clicked consolingly. “Dis is nod yo’ fault.”

“I’m his father, of course it is my fault,” sang Triton bitterly. “Where did I go wrong.”

“Dese things 'appen. Younglings will always rebel,” clicked Sebastian. “Bud do you dink dat it es a gud idea fo’ da prince to do everything on es own?”

“You said so yourself. He needs to struggle to learn responsibility,” sang Triton. “And I can’t think of any greater struggle than learning how to be a father.”

“Bud dun you wanna see yo’ grandson?” asked Sebastian.

“Of course I do,” answered the king. He flared his gills out in a sigh. “But how could I?”

With the new chasm in his relationship with Riku, it would be hard to have a connection with his grandson. Triton wished that the prince would see reason and learn responsibility. He hoped that pushing him away was the right choice, and that this pain of separation was worth it.

{{———————————————–}}

Aqua and Terra were swimming quickly to catch up with Riku. They needed to talk to him about the current situation, but something else was bothering Aqua, enough that she suddenly stopped moving and clicked, “Wait.”

Terra splayed his dorsal wings and wheeled around to face his chosen. “What is it?”

The mermaid gave Terra a serious look. “Did you really believe that I mated with the prince?”

This was one of those questions that Terra knew was going to get him into a lot of trouble. He looked away instead of answering.

“You doubted me?” sang Aqua with dismay.

“I don’t doubt your feelings for me,” answered Terra in low notes. “But I also know your loyalty for Lumina. I had to ask myself if you would you be willing to do it if it was for the sake of our kingdom.”

“And the answer you came up with was yes,” clicked Aqua, her expression suddenly flat.

“You’ve been a freedom fighter from the moment you’ve learned to use a sword,” sang Terra. “You would do anything to protect the kingdom.”

Aqua put her hands on Terra’s shoulders and sang emphatically, “You are my kingdom.”

Terra’s eyes widened, and then his look softened. He placed his hand on Aqua’s cheek and stroked her skin tenderly. “You’re really making me hate that prince.”

“He needs help. If his father won’t step in, then we should. Who knows how the next heir will turn out with Riku as his influence,” sang Aqua.

“Good point,” conceded Terra. “But do you really want to give parenting advice when you haven’t had a youngling of your own?”

“It’s better than not having anyone to rely on at all,” sang Aqua. “Would you rather that he turn to Xehanort for help? Because as long as he has the Trident, you can bet your fins that he’ll be visiting enough to be considered a godfather.”

“How about we just make a youngling of our own. Then we will be qualified to tell him how to raise one,” sang Terra in playful notes.

Aqua’s gills flared and her cheeks stained purple with embarrassment. She pushed Terra away and quickly began swimming towards Riku’s chambers. The sound of her chosen’s laughter echoing behind her made her blood rise even more.

When they arrived at the prince’s chamber, they found that Riku was struggling to find a way to hold his door open and put Sora inside the room without getting him squished by the giant boulder. In the end, he decided to wedge the Trident against the rock to hold it in place while they swam through.

Aqua inhaled deeply through her gills to put away the shock of seeing Riku using the powerful weapon as a doorstop. “Your majesty.”

Riku paused in the middle of what he was doing to give Aqua a glare. “What do you want. My business with you is already finished.”

“I want to help,” sang Aqua. “I don’t think that you should have to go through this alone.”

The prince hissed. “So you can win points for your kingdom? You’re as ruthless as the orcas.”

“This isn’t just about the kingdoms. It is part of it, yes, but look at him,” sang Aqua. She gestured towards the quiet human. “He’s going to need a lot of help.”

“All he needs is me,” clicked Riku as he struggled to dislodge the Trident from the door.

Aqua flared her gills with worry. The prince was so full of pride; he couldn’t see how dire his own situation was. Worse than that, he managed to drag a poor human and an unborn youngling into this mess. The mermaid decided to help Riku by wordlessly holding the stone back so that the Trident could be freed easily. “Just think about it. Terra and I will always be available. We just want to see that everything will be alright.”

Instead of answering, Riku hit the rock with his tail so that it would slide back into place. Aqua shook her head at the prince’s behavior.

“Give him some time,” sang Terra. “Male younglings really aren’t into accepting a mermaid’s help.”

“And yet, the Trident will only pass on to a male heir,” sang Aqua wryly. “No wonder this kingdom is always on the brink of falling apart.”

{{———————————————–}}

The prince laid Sora down on his clamshell bed. He didn’t understand why his human was so silent. Maybe it was a side effect of the magic, or maybe he was just that shocked. The thought that this was how things were going to be from now on gave Riku a fluttering sense of apprehension.

“Sora,” he sang to the still mer. “Talk to me. It’s just you and me now." The prince touched Sora’s face, and then he gently kissed his lips. His mate didn’t so much as budge or blink in response. Instead, he stared up at the chamber’s ceiling, as if he could see the sky and land beyond the water.

"This world is better than yours,” clicked Riku. “You’ll be royalty here. Don’t let my father scare you. As long as you’re with me, you’ll be okay." He wrapped his tail around his human and nestled into the clam beside him. "It’ll be alright.”

Words would not come to Sora. He was in deep shock over everything that transpired. He didn’t know if he was dreaming, or if this was some sort of twisted afterlife that came with death. This was not what he wanted. Out of all the times Riku saved him, this was the first time he wished that he had been left alone.

What scared him the most was the fact that he would have to depend on the prince for everything. If he ever wanted to be human again, then selfish, prideful Riku, who just pushed away his own dad because he wanted things his way, would have to allow it.

Sora was scared. Very, very scared.
