In Horizon, a few days went by rapidly, as Orion, Amelia, and Dramia worked on creating a massive approximately circular hole a kilometer away from the house.


    Digging out the ground of Horizon was more a matter of patience than skill, as it required the constant drainage of Orion''s magic for it to work, something he didn''t knew until they started.


    A hole, similar to the one that drained his magic when he obtained the tablet appeared over the spot Amelia needed dug out, sizing roughly to five meters in diameters, absorbed the ground slowly all the while they worked to complete the project.


    This gulf needed to be deep for the sirens to live comfortably, and have a good amount of sea life prosper so that the biome created in Horizon remained stable over time.


    But for some reason, their endeavor was rewarded by the tablet itself.


    At one point, the device sent a notification like it did before.


    -


    <Horizon Project n°1: False Sea, Siren''s Gulf.>


    <Requiring materials: ...>


    A list of everything needed was then given for Amelia and Orion to gather.


    Sand, seawater, wildlife, plants and sea grass. There was quite a lot to gather.


    Dramia was the one to prepare food for them. There was no real reason to rush the project, but after a few days, she realized her fairy friend was being a little depressed.


    That''s when she understood. Being away from Drania, even if it was her choice to follow, slowly impacted her spirit.


    So, after six days, the digging was done.


    From the back wall, a deep opening had been created. Precisely, Amelia managed to remove fifty meters of matter.


    The shallows went from the coast to the steep incline leading deeper. The gulf was a kilometer wide on the far left, opposite to their house.


    Fifty meters of shallows around the coast, with five hundred fifty meters of deepest waters.


    At this point, there was a problem that only appeared when Orion remembered it.


    In the sea, there had to be a marine current. Without one, the water would simply stagnate, leading to various problem, also impacting their own life. In just a few days, it would become a cesspool full of dead beings, or a swamp.


    How could this problem be resolved? This is were the tablet once again shined.


    A simple button, <Settings>.


    With that, some effects that could only happen with wind, the rotation of the planet (Coriolis Effect), and thermal vents suddenly were simulated.


    Those setting impacted not only the area around the false sea, but also the whole of Horizon.


    To say that it was surprising would be an understatement. Suddenly, they felt a rumble under them, and a lot of things began to activate.


    At that moment, Orion realized that this space hid a lot of things he didn''t knew.


    Many simulations were unlocked, and the space changed as if it was a small piece of Triazils detached from it.


    The air felt more real, the sky obtained a false sun formed with a sphere of light, and even clouds seemed to be able to appear, but there was no water for that option yet.


    Maybe rain could be possible at some point. But how that would work in a confined space, even Orion had no idea. He decided to let the future Orion understand more about his own ability.


    With everything done and ready, it was time to fill the empty gulf.


    So, Orion recalibrated Horizon''s flow of time to Triazils, and with the girls, finally returned after seven days.


    ~


    "Quite a project, isn''t it?"


    "Don''t say anymore. I''m done with this stuff for a moment."


    Dramia began to poke at Orion with her words.


    Tired from constantly being drained of magic, he was done with these kinds of project in Horizon for quite some times.


    "I''m done too. Let''s return to Karteira and Drania."


    With her arms dangling on both side, and her shoulders slumped, tired from holding the tablet constantly, Amelia walked toward the hub of portals.


    "Yes, the fact that I still have to expand more magic to end this project just..."


    It was rare for Orion to make grunting sounds, but this was to show how excruciating this was. The fact that they rushed it without taking much of a break might possibly be the reason for why he was like that.


    With a sigh, Amelia and Orion exited Horizon, leaving Dramia alone.


    "Since when this place sustains itself while he is out?"


    This little detail, which was impossible to know because Orion was always the last to exit, was finally discovered by her.


    She shrugged and followed, entering the portal.


    The moment the setting sun of Triazils setting past the sea, the heat of the desert, and the crashing sound of the waves, her senses instantly returned.


    This tale has been unlawfully obtained from Royal Road. If you discover it on Amazon, kindly report it.


    Her sister was happily playing with a piece of Kelp while talking to the sirens.


    ''It''s way too hot around here...''


    But she still hated the desert''s heat.


    Quickly joining with Orion and Amelia, she spoke on her previous finding.


    "Orion, that space stays activated when you are not in there?"


    He nodded.


    "Since the creation of the tablet, it constantly stores a constant amount of magic to maintain it. I stopped it before because I was scared the magic stored inside my father''s ring would deplete while I was away, but now that it automatically drains mine when it needs to, I can keep it running."


    "Oh."


    Turning to Amelia, he said.


    "We''ll see if the device can absorb some of your magic too. I would like to recover the ring if possible. I know the amount to maintain the house is abysmally small, but still, I don''t want to risk losing it."


    With a smile, she agreed.


    "Sure. Let''s finish this first though."


    "Alright."


    The three of them finally stopped talking, and joined up with the other two.


    "Sis! How was it without me?"


    Drania looked worriedly at her sister.


    "Quieter. A bit too much quieter."


    ''I''m just glad to see you after a week.''


    As if reading her mind, she nodded.


    ''Hmm. Me too, though it''s only been close to three hours.''


    While those two had their twin moment, Amelia and Orion stopped in front of Karteira.


    "I can''t believe I haven''t seen you in seven days. We''ve never been apart since leaving the fairy realm."


    Amelia approached Karteira and hugged her. Orion walked next to them, and patted her too. This was his way of saying that he missed her too.


    For the ones having stayed in Triazils, it was hard to understand.


    The sirens silently looked at all of this, not sure on what to make out of this scene. Until Orion looked in their direction.


    "Preparation as been done. We''re currently finishing with the resource gathering."


    His hand extended forward, and a massive portal was formed inside the sea, far behind them.


    When they felt the water current suddenly change, they began to panic, but they noticed the white void with sparkling darker stars sucking water at an incredible pace.


    ''It''s harder than I expected. I can''t control how much water I send over there.''


    Knowing that, he gritted his teeth.


    "Amelia, can you go back to Horizon, and look at the amount of seawater we need? Just tell me when I have to erase the portal, please?"


    Noticing the sweat forming on his forehead, she immediately agreed, and waited for the portal to form next to him. Hurriedly, she ran through it.


    She instantly found herself in front of the gulf. But something was off.


    "Orion! There''s no water inside!"


    "What?!"


    Passing her head through to tell him, he almost stopped everything.


    "That''s impossible. The water should be there."


    "I''m going to check again."


    When she straightened, something else was off now.


    "Huh? When was it this dark? Am I going crazy?"


    Just when she said that, she lifted her head.


    "WHA-! THE TABLET!"


    Panicking, she hurried to the tablet that was on the table not far from her.


    *BIP*


    She looked at the number growing at an incredible rate, and stared at the source of the darkness.


    A giant orb of seawater was floating in the air, surrounded by multiple dark void hole. It was growing at a tremendous pace.


    "Even at that size, it''s still not even halfway?!"


    Running back to the portal, she quickly described what was happening, to his relief.


    "Great, just tell me when it''s full."


    "Yes!"


    After that, it took three minutes for the sphere to attain a size that could easily destroy a city. Amelia looked tiny in comparison.


    "A kilometer wide and fifty meters depth is no joke..."


    She passed through the portal after placing the tablet back on the table.


    *BIP*


    When she heard the last notification sound saying that it was done, she walked through the portal.


    "You can stop, we have enough."


    Karteira was swiping his sweat off with a handkerchief, as he finally stopped and erased the portal.


    Another grunting noise came out of his mouth.


    "I''m tired."


    "Good work. Rest a bit while I take care of the rest."


    But he shook his head.


    "I''ll rest once it is done. The sun is setting, we don''t have much time left."


    He pushed Karteira''s hands away gently, and walked past Amelia through the portal.


    "Why can''t he rest, for the love of the world! Stubborn man!"


    Pouting, she followed him.


    "But that''s why we love him."


    Smiling while shrugging, Karteira said, before walking to the sister, and the pile of sea lives and plants next to Drania.


    ''How am I going to take that with me? Should I ask Orion to warp them?''


    ''I''ll ask later. I''ll wait here for now.''


    On the other side of the portal, Amelia was pressing on the tablet.


    *BIP*


    The void holes at the bottom of the massive seawater sphere disappeared, and without wasting any time, the water crashed at the bottom of the gulf.


    Amelia carefully controlled how the water was to fall inside. While this happened, it let Orion rest a bit.


    Slowly, under their gaze, the water orb was reduced in size, while the water level rose.


    Ten minutes later, only a small sphere of seawater was left. This leftover was immediately sent back to the real sea.


    "Alright, what''s next? Sand?"


    "Yes, I can do that though."


    Amelia brought out her earth element, and in less than a minute, formed the required amount of sand necessary for the project.


    *BIP*


    The moment she clicked on the button to accept, the sand was absorbed by a void hole, and the landscape changed.


    The whole golf was now made of pure golden sand. Twenty meters out from the coast were also changed to sand.


    "I need a bit of gravel too."


    This too was added at the bottom of the gulf.


    "Plants or animals?"


    "Plants. We can bring whatever, it will transform the terrain by itself."


    Orion nodded, and returned to Triazils.


    *Splash*


    A pile of wet algae and breathing creatures fell next Amelia.


    "Ugh!"


    She was instantly disgusted by the noise and the looks of it.


    "Not enough I guess?"


    Back, Orion asked.


    "Just a bit more. It''s missing corals, and sponges. I also need ten kilogrammes of plants."


    "I''ll bring the rest."


    He turned around and disappeared once again. With the help of the sirens, he managed to bring everything back, while also carefully avoided killing the delicate creatures he needed, especially the corals.


    "Alright, I just need to click there, and..."


    *BIP*


    <Simulating: Wind / Currents / Thermal vents / Waves.>


    The pile of creatures was absorbed, and placed randomly at various spots of the sea.


    <Remaining tasks: Add fishes / Add sirens.>


    <Danger: None. Constant observations will be needed by the system.>


    Showing the notification to Orion, Amelia smiled.


    "After that, we''re done. For real."


    "Thank the world."


    He smile, and returned to Triazils.


    With the help of Eagle Eye and Calm Analysis, Orion managed to find large schools of fishes, largely sardines and tunas, but also a few sharks and some octopuses, squids, and whatever fishes were near the coast.


    He needed beings that lived in shallows, and depth.


    ''I''ll go and see if Kamala can find me a fisherman that could bring me some alive specimens of fishes we can''t get from here.''


    Still satisfied with his haul, Orion sent Amelia to check on the tablet to see for problems, but she returned with a smile, and good news.


    "All of these creatures will most likely respect the food chain. The tablet said that there was no danger still."


    "Great. This leaves only the last part."


    He turned to the sirens, who until now, were left in the shadows about this whole project.


    "Do you want to come in a place were no conflict, and were only peace exists? Or do you wish to stay here?"


    He hoped that the whole project wasn''t in vain. But even if it was, there was now a sea in Horizon.


    "Eh? Where is that? Behind that thing?"


    One of the siren pointed at the portal.


    "Yes. You see, I control a space out of this continent, where only me and a select few can enter. There is no risk of being hunted down on this side."


    Some of them looked worried.


    "This sounds too good to be true. Aren''t you going to abduct us too?"


    "Well... of course I am abducting you. There''s no other ways to describe it. Maybe ''relocate''?"


    He joked a little, but they didn''t really liked it.


    "I know, you won''t follow blindly. Can one of you come with me? I''ll send you back so that everyone know I can be trusted afterward."


    They all looked at each other, and all gazes fell upon the weakest member of the sirens, the same siren that asked for water when Orion saved them.


    She had lifted her hand out of the water.
