Until Shadowhunter is saved, I swear to God that I will never stop with new Malec fanfictions. Never!

This new AU would not be possible if not for the amazing KDesai, who helped me with the idea. You should check him/her out. Now, without further ado, enjoy this new story.

There's a kingdom that exists. The beautiful and almost utopian kingdom known as Idris. The home of the strong and tattooed knights called the shadowhunters. In the kingdom of Idris, the shadowhunters are warriors recognized by their angels. They protect the kingdom from demons and monsters that roam the woods, the ocean and the sky. This kingdom is ruled by a small circle of important diplomats called The Clave. Apart of The Clave are the Lightwoods, the Herondales, The Fairchilds and the Morgensterns. The Clave does it's best to protect their shadowhunters along as protecting downworlders, another kind of human that sometimes resides in the kingdom. But this story isn't about the Clave, or the kingdom of Idris or even the demons that torture the kingdom. It's about one young boy. A shadowhunter. Alexander Lightwood. Alexander, or Alec as he prefers to be called, is the eldest son of the Lightwood family. Along with his sister Isabelle and his parabatai, Jace Herondale, he works hard to keep his kingdom safe and he make sure that the laws stay equal and fair.

Alec is skilled in archery and horseback riding above all else, but all of his skills are very much awarded out in the field. But, as much as Alec loves being a shadowhunter, being a Clave diplomat and being an honored member of society in his kingdom... Alec loved the simpler things in this kind of life. Alec had always and will always love the beach. Growing up the palace and training to be a knight had always kept him inside. But whenever he had the chance, he always ran out to the beautiful white sandy beach and watched the beautiful crystal blue waters crash on the sand. It always was beautiful and immediately made Alec's mood the better. He loved going to the beach at the night more than he liked going to the day, but he would always go if he found the time. Alec loved the dark blue waves that would look like they had a spotlight shining down on them and the feeling of the pearly sand in between his fingers and toes. Alec walked out to the beautiful beach that night, looking at the dark waters before him. He set down his bow and quiver and walked over towards the ocean. The sounds of the water crashing on the sand made Alec smile.

He looked out at the beautiful sea before him. Alec leaned forward to take off his boots when he heard the sound of angry grunting coming from his right. Alec stood back up and slowly backed away, reaching for his bow and arrows. The sound of grunting and what seemed to be rattling chains seemed to be getting harder and way more aggressive. Alec grabbed an arrow from his quiver and held his platinum bow up. He slowly crept closer towards the sound of the rattling, crunching and grunting. He made a slowly turn at huge boulder and pointed his bow at what made the sound. But he started to lower it at what he saw. A young man with shining skin was laying in the sand, struggling against a iron net that was covering his face and body. Alec would say that the net covered his legs, but he couldn't. Because this almost shining man didn't have legs. Or feet. Instead, his lower body had almost mesmerizing tail. Covered in light and dark purple scaled that looked like they belonged in a safe for protection. The fin looked like it was made of silk, the color of the lighter shade of purple.

Alec knew that this man was a downworlder. A man that resided in another kingdom that had it's own government. This shining man was a merman. His sparkling tail proved it. The purple tailed merman in the net stopped struggling when he found out that someone was in front of him and they also had a weapon. He was just staring at him. The merman just stayed still, holding the chained links that connected the net, looking at Alec with fear in his golden cat eyes. Alec stopped think so hard and he looked over at this merman. He didn't realize that his eyes looked like two spheres of gold. Like portals that would Alec was afraid to get lost in if he stayed looking deep into them. And then his perfectly shaped chest was bare. Hanging from his neck were multiple necklaces and the fingers that were holding the nets chain links had a multitude of rings on it.

After a few moments, Alec noticed the fear in his eyes and how he stopped struggling in the net. Alec threw his bow down and put his hands in front of him, signaling that he was alone and that he wasn't going to hurt anyone. "It's okay..." Alec said. "I won't hurt you."

The merman stayed still under the iron net, stiff as a board and looking at Alec with fear in his eyes. Alec moved closer to him and looked for whatever kept the net connected to this shining merman. He found a link of chains that were interlocked on the bottom of the net and forced them apart with his brute strength. The merman slowly snaked his way out of the net while clawing to get out. Alec pulled the net away from him and allowed him to try and snake over to the ocean. Alec noticed that this man wasn't getting as close to the ocean as he wanted. "Hey." Alec called, moving over towards the cat eyed man with a purple tail. "Let me... let me help you."

The man didn't protest or even say no when Alec moved forward and pulled him into his arms, holding his tail under his arms. Alec walked towards the water, not caring that his armor was getting wet and would possibly rust later on. He walked into the ocean and allowed himself to get the water up to his stomach before gently laid the man into the water. His tail seemed to shine in the water and moonlight shining over it. He went into the water and dunked his head under the water. Alec nodded and started to walk off back to the sandy beach, when he saw the fin of this man's tail block his walking path. Alec turned and saw the man looking up at him with a closed mouth smile. "Thank you shadowhunter." he said with as he ran his arms and fingers in the waters.

"How did you... how did you know that I was a shadowhunter?" Alec asked, raising an eyebrow and trying to hide his smile.

The merman chuckled and pointed one of his ringed fingers at Alec's neck. "You have a rune right there if you didn't know." he said.

Alec's hand went to the deflect rune that he had drawn there. He chuckled along with the merman. "Yeah..." he said. "Right. I forgot. So... how did you... how did you end up in the net?"

The merman smiled and he ran a hand through his dripping wet hair. "Not going to lie. It was a bunch of other shadowhunters. I was just swimming a little too close to the surface when the net caught me." he said. "They explained that they were going to come back for me and get rid of me if I hadn't of suffocated. Thank the angel you showed up."

Alec smiled and nodded. "I'm sorry that that happened. Do you remember what they looked like? Maybe I can find them and make sure that they're punished for what they did to you."

"I wish I could. But all that I can really remember is that they were in dark blue hoods." he said with a shrug in the water.

"I'll be sure to let the shadowhunters know to look for these... kidnappers. They'll be deruned for attacking an innocent downworlder."

"Oh please. I am anything but helpless." the man went back under the water and swam closer to Alec. Alec blushed as the merman came back up the water and he held Alec's chest plate. "But if being helpless meant that I could I met you, I don't mind being helpless." Alec nodded. The shining merman looked back out at the sea and smiled. "I should go back under."

"Oh... yes. Yes, you should go." Alec said, before realizing what he was saying. "No, that's what I meant. I don't mean that I want you to go. It's just... it's just a matter of... of being-"

"I can tell that you get flustered a lot don't you?" The merman said. "Well then, if you don't want me to go, can you tell me your name?"

"Alec." he said with a smile.

"Is that short for something?"

"Yes... it's uh... it's short for Alexander."

"Well then, thank you for saving my life Alexander. I shall definitely return back to this beach tomorrow."

The merman plunged back down under, much to Alec's delight. Until he realized that he didn't get the name of this purple tailed man. "Wait!" he yelled out. The same black haired man pulled back up to the surface and he looked over at Alec even though he was farther away. "I didn't... I didn't get your name!"

The man smiled. "It's Magnus." he said, before plunging back into the waters below. Alec smiled, remembering how the moonlight shone down on his skin and on the waters underneath him. Alec smiled and walked out of the ocean. He grabbed his bow and quiver and looked back out at the ocean. He smiled. There was something about that man with the beautiful tail, many rings and soaking wet back hair that made Alec blush like crazy. Alec walked off the beach and met with his horse, Ilio, who he left to graze in the sand. He grazed his mane and smiled at him. "You should have seen him Ilio. He was... unlike anything I've ever seen in my life."

His horse neighed and nuzzled his cheek, making Alec laugh. Alec hopped onto Ilio and grabbed his reins. He looked back out at the waters and smiled as the moonlight waved and shined all over the midnight blue waters. His thoughts were on Magnus. Alec really did want to see him again. He wanted to see him for as many days off that he could possibly get. As many hours as he could spend away from the palace. As many hours on that beach. As many hours getting to know that dashing merman with the mesmerizing purple tail, fins and shining skin. Alec smiled and looked down at Ilio. "Come on boy." he said. "Jace should be looking for me."

Alec snapped the reins and rode off away from the beach. Alec didn't notice as he rode with Ilio, but Magnus came back out from the waters. He swam over to the rocks and watched as Alec rode away from the beach and away from him. Magnus smiled and looked over at him as his disappeared completely from his view. "Alexander..." Magnus said with a smile. "Hmmm... how endearing."

Magnus plunged back down into the waters that crashed below.

Other than the kingdom on the surface of the water, there's the kingdom of Edom. Where the mermaid, merman warlocks reside. The kingdom, unlike Idris that is rulled by a group of people, is ruled by one king. King Asmodeus. A kind man to some, but a cruel, heartless tyrant to others. And along with that king, is his only living son. Magnus Bane. The young prince had seen how evil his father could be when he took the lives of the other princes and princesses that he fathered. All Magnus could really do was wait his turn. But Magnus was incredible at magic. His father seemed to keep him alive long enough for his power to really grow. Magnus was always on order to stay underwater, in the palace, in the kingdom, so that his father could watch him and make sure that he didn't ever leave the kingdom. But Magnus was always drawn to the surface of the waters below. He was drawn to swim around higher than he should. Dance with the waves above. Even press his hand against a fisherman's boat when it docked. The surface above him seemed like pure magic to him.

But then he was captured.

In a net.

And then he was rescued. By that beautiful, hazel eyed and flustered shadowhunter. Alexander. Magnus thought of how incredibly noble he was for saving him from that iron net, suffocation or a brutal and unneeded death from those disgraceful shadowhunters in hoods. Magnus was glad that Alexander had saved him. Magnus wanted to make due on that promise that he made in the water while he caressed Alec's armor and body with his tail. He couldn't wait to come back and see that... intriguing shadowhunter. To see that intriguing Alexander. Magnus swam back down below the ocean and through the corals and sea shells and into a small under kingdom. The heart of the underwater downworld. Magnus swam as best as he could, undetected and swam inside one of the windows of the golden coral that made up the Bane palace. He swam inside his bedroom and moved towards his mirror. He looked at his reflection. He wanted to make sure that no one noticed his absence for so long over see the indents from the iron net that he had been trapped in for a few hours.

Magnus smiled, seeing there were no marks, and more importantly, that he looked decent for that shadowhunter, with a rune on his neck.
