According to mythology, this whole world is created by the God of creation using four elements. These elements are air, water, earth, and fire. Every single living creature roaming on this world is the creation of the almighty God and they are living based on these four elements. But chaos raised when it was time for the god to divide the power and responsibilities of handling his creations among his children. And from this chaos, the world also got divided into two parts. The good ones who cared about all the creation became our gods and goddesses and started living in Olympus as immortals. They divided the world's responsibility among themselves and take proper care of them. But the only one who was so obsessed with the power of the almighty God that, he parted himself away from the rest of his siblings and parted his own world, which we call the hell and the evil one as Satan.
The god and goddess chose each of their elements and separated their duties from each other. And according to their elements, they became the god and goddess of different creatures. For example- Poseidon became the god of water, and he watches over Mermaids, Hermes became the god of air, and he watches over Angels, Zeus became the god of thunder and rain, and he watches over Werewolves and vampires, etc. Satan who was the evil god of fire also has his followers. We know them as devils and demons.
By the first trick of Satan, the almighty god's plans got destroyed. He had to let go of his loving creation, the Humans, and send them into the earth according to their curse. And since then the evil ones got banished to enter heaven, and they had to stay in hell forever. It raised their anger more, and they became god's biggest enemies. But from this, all god's responsibility increased, and now they had to take care of these cursed ones too. To make everything easier, they had to give the responsibilities of these supernaturals to their children because taking care of the cursed ones is way harder than taking care of the supernaturals. And to do that, they send them to live among them as mortals to help them in their troubles. They would rule these kinds as their king and queen until their next generation is ready to take the place. Only then they could enter Olympus and become an immortal god. These rules are made by the almighty God, so Satan also had to follow them.
According to these rules, Poseidon's son Triton became the King of the Mermaids, Hermes daughter Angelia became the Queen of Angels, Zeus's son Apollo became the king of werewolves, and Vampires, and Satan's son Aaron became the King of the Devils and Demons. Now they have to wait for their sons and daughters to come into their age to take the throne of the King and Queen so that they could become immortal and get the chance to be the god.
Although all of them live in different parts of the world, and they possess different kinds of elements of power, King Triton and Queen Angelia fell in love with each other. At first, all the gods disagreed with their relationship, but later the almighty God announced to let it happen what they want. Love is the most powerful weapon in this world. It can create a better kingdom or destroy one with a snap. It's better if nobody comes between two loved ones.
After getting the blessings of the almighty God himself, King Triton and Queen Angelia married each other and became each other's, soul mates. Along with these two supernatural rulers, both worlds became one too. The results of this unity were amazing. Both air and water world became happy with each other and made a strong bond of friendship. They started living in a land together too.
The only person who was not a bit happy with this unity was King Aaron or the devil. He was planning on gathering all the evil souls for a great war, which includes all demons and vampires. Yes, he managed to manipulate the vampires against King Apollo and made them work for the devil. They became demons themselves and killed every single soul that comes in front of them. Now the devil's only worry was that, if both kinds of rulers have a baby together, it will become the most powerful one among all. That's because he or she will possess both of its parents' powers, which will become undefeatable. Nobody will have enough strength to fight against him/her. It's going to become the biggest obstacle of his path to become the almighty God.
The only way to remove this obstacle is for his own son Erlik. So, to make sure of the success of his plans, he started training his son to be the best warrior since his early childhood. He taught his son to use his strength and power of fire, at its most. He taught him to fight against a large group of enemies altogether. He created his son to be the most powerful warrior ever born. But he never loved him as a father does to their sons. His only target was to create him strong enough to give him what he wants, although Erlik craved for his father's love always.
It took the devil, 20 years to build his son as he wants. But the final result came out amazing. Erlik became so powerful that even all the demons can't defeat him together. Everyone fears him to death in hell. And the day to make the devil's long waited plan succeed came. On the 20th birthday of Erlik, the devil sent his son to the mermaid and angel world to kill the future Queen who was born out of King Triton and Queen Angelia.
“Son, it's time. It's time to make your father proud. It's time to give our plan success, to give me the results for what I trained you for. I want you to go to their land and kill all the thorns that are standing in our way. But don't hurry anything. Keep your patience until you find the one we are planning to defeat. You already know what you have to do, don't you?” The devil asked his son.
“Yes, father. I know what I have to do. I will keep my patience. I won't reveal my true identity until I find the one. And when I find this girl, I'm going to crush her and burn him in the fire.” Erlik answered in anger.
“No, no, no, my son. I'm not sending you there to kill her. I want you to gain all of her powers. And for that, you have to use your charm and lure her in. When she falls for you, I want you to drink her blood and suck all her powers inside you. Once you gain all three kinds of power, nobody will be able to defeat you. Not even our biggest enemy, the almighty God. Then we will throw him out of his throne and become the almighty God ourselves.” He finished his speech with an evil laugh.
“As you wish, father. I won't disappoint you.” Erlik bows down in front of the devil king.
When it was time to send Erlik into the Mermaid land, he dressed up himself as one of the cursed ones. He disguised himself into them because they knew that if king Triton finds out that he's a devil, he would kill Erlik in a second. After all, he is going there powerless. King Aaron thought to take his devil powers away until he returns to hell with success. He is afraid that his son would be exposed if he loses control of himself and uses his power in front of everyone. If something like that happens, all of their plans will get destroyed. And he doesn't want to have failure at this stage of his long-awaited plan.
Erlik agrees to his father's wish and gave up on his power of fire. He wants to give his father success, which he got hardly been trained for since he was a child. He knows that his charms and his strength are enough to win in this battle. When he was all ready for his mission, king Aaron used his power and send him out of hell upwards. But not before saying some harsh words to him.
“Bring me success or don't come at all. This is the test in which you have to prove yourself as a King. Only then you will get my affection. Prove me that you deserve to be loved.” Erlik just shakes his head at his father.
When Erlik came out of hell through a c***k on the ground, he found himself inside the depth of the ocean. Unfortunately, this is his first time out of the fiery hell and his first time getting touched by water. Without his powers, he's just a helpless soul who doesn't know how to get out of this depth of water. He squirmed under the water and tried to walk out of it, but failed miserably. He tried to push himself up, but it didn't work. While still trying to get out of the water, he was getting out of breath. Soon he started losing his consciousness, and he realized that his disgraceful mortal life is going to end.
He got disappointed in himself by thinking that his mission is coming to an end before it properly started. He truly is a disappointment to his father because he couldn't even come out of the first challenge his father send him in. He doesn't qualify to be loved by his father, or anyone for that matter. Soon he was losing his senses, but he still kept squirming to find a way to get out until his body started getting limp. His eyes got closed, and he was falling to the surface of the ocean grounds. But suddenly he felt a pull in his hand.
As he tried to grab the thing that was pulling him, he felt something burning under his touch from the heat of hell he was still carrying or the fire he possessed on his palms a few seconds ago when he was still on his land. He instantly felt that thing leaving his hand as he was again falling down. He almost lost the hope to be saved when he again felt that thing or that hand pull him out of that depth again. He wanted to know who this person is who's trying to save him, so he tried to open his eyes. But he couldn't see anything clearly because his eyes have already started to get blurry from getting half unconscious. Still in this condition he managed to notice that, it's a girl with white hair and a white shining tail. He understood that she's a mermaid who saved his life before getting completely unconscious.
When he gained his consciousness back, he found himself on the land. He searched around himself and found nobody around. He was sitting alone in the sand of seashore with no proof of any living being around him. He forced himself to remember what happened back inside the water, and he could only make out the attire of the mermaid that saved him. He realized that he has burned that girl somewhere and there's no way she's not informing her king about my arrival. She probably revealed everything to them by now, and they are probably on their way here to kill him.
He made himself ready to fight against his enemies. If he has to die, it's better while keep fighting. But even after waiting for about an hour of their arrival, nobody came. It made him wander that was that girl he saw under the ocean was real or not. If she was then why would she save him in the first place even after realizing his true identity? Was that girl only a hallucination of his unconscious state? But then how did he make it out of the ocean? It was getting really confusing for him.
After debating himself for few more times, he decided to forget that matter and only think about the mission he came here for. But one thing he knows for sure now that he needs to stay away from the ocean, no matter what.
