I got this idea from a story form 2015 that only had one chapter, it was too good to never get the chance to be anything more.

As we have seen in the Percy Jackson books, gods have different forms. Hades is Pluto and so on, but at the same times, some religions have gods that do not have any other form in any other religion. For the sake of this story, Hades, in the Christian religion is a form of the Devil, however, the Christian god has no counterpart in any other religion. Meaning, aka, Nico is, in some sense of the world, Son of the Devil, the king of the demons.

Nico, age 10

( Age's will not be the exacted as cannon

Nico was lost, cold, and hungry. He has been gone from camp half-blood for about two weeks now and he knew that in truth, that was the only place he would have a warm bed and food: however, he did not want to go back, could not go back, Camp half-blood was where he was at. Where the boy that killed his sister was at. So with the promise of never going back and thoughts of revenge he pushed on through the cold city of new york, Winter was setting and the cold was sinking into his bones and with the thought of food losing to the thought of warmth, finding a place to sleep became the new main priority.

However, when did anything ever work out for Nico? Hours went by and before he knew it, it was in the wee hour of the morning, the streets were mostly empty and the few people that still remind were …..sketchy to say the least. He played it off as a trick of the cold but he was pretty sure one had a tail and horn, and the thing winked at him. That made him walk a bit fast.

After finding nowhere he turned into an alleyway, in hopes to get away from the wind. It did not help much. The ten-year-old boy sat against the wall and pulled his knees to his chest. He missed his sister so much...but at the same time, he was so mad at her. She left him, left him for a group of girls that she knew for less than half an hour vs the brother that she spent her whole life with. Was he really that annoying? So annoying that is own flesh and blood would leave him without a second thought, maybe it would have been better if he was the one to die. Yah, he was sure that everyone would have preferred it that way. His own father did not even claim him, did not want to recognize Nico as his child. His memories of the past were still fuzzy, but he was sure that whoever his mother and father were would have preferred if he would have died instead of her as well. He would probably die soon anyway, he could feel his body slowly shutting down and he was sick of fighting the hunger and cold, so he let his eyelids droop shut. Not sure if he would wake up again.

The ten-year-old did not take note of the fact, that the shadows were slowly stalking closer around him, in till, they covered him completely and swept him away to the unknown

Magnus Bane, eyes trained on the face of his boyfriend, Alec Lightwood, they were currently sitting in Magnus apartment watching some old TV show. Magnus had no idea what was going on in the said tv show as he was to busy taking in every little bit of Alec's face. Alec, as if being able to feel eyes on him turned to Magnus and gave a small smile. " Can I help you, Magnus?" Alec asked his voice slightly rough form the hours of them just sitting together. Mangues cats like eyes sparkled slightly " nope, I'm perfectly happy just staring at you" He said with a small smirk.

Alec, no longer interested in the tv show, shifted slightly so he could look at Magnus better. " I have been thinking, we have been dating for almost 4 months now, I think it may be time to tell my Parents" He looked as if he was almost done but started speaking up again" I...I know they may not approve but, what's the worst they can do? Disown me? ...well yeah I guess that probably would be the worst they could do," He was rambling at this point" but I could just move in with you if you okay with that I mean" Magnus cut off the dark-haired male with a small kiss to the lips.

" Alec, if you for sure about telling your Parents, I would be more than happy to have you living here with me if the worst happens" Alec smiled at his words and leaned forward to ki- BANG

Magnus sat up in his bed as a loud noise filled his apartment, he looked around and remembered where he was at, in his bed, at his home, alone. It has all been a dream. A very good dream mind you and something woke him up from it. If the said thing that woke him up was not his boyfriend he was going to be very disappointed, and very mad.

Pulling his silk nightgown( what, it was much more comfortable) closer to himself as he got out of bed he started to make his way to his living room. So imagine his surprise when he did not find his boyfriend, or ever an intruder for that matter, no, he found a dead looking child laying on his floor.

"Well...there goes my quite Wednesday night," the cat-eyed man said as walked a bit closer and leaned down slightly placing a hand on the boy's wrist. The child's skin was dead cold but he could feel a light heartbeat. The child looked pale and much too skinny. " How in the world did you get in here" Magnus was not good with children, well, to him most people were children compared to him in age. But he was never good with children, children, either. However, he was not heartless. Picking up the child he placed him on the couch to his left.

A small shocked sound left Magnus lips as he felt the magic that was practically bouncing off the small boy's skin. A warlock? Warlocks were in the most sense of the world immortal and the most uncommon of all the downworlders. They were not born very often. Magnus in his about 800 years of life has only ever heard of 12 new Warlocks being born. The boy in front of him could be no older than 11, and warlocks don't stop aging till around 18-21 so there was no way this boy was older then he looked. You see, Warlocks were the offspring of a human female and a male demon. In some odd cases, those genders were swapped but not very often. With a quick one over the boy, he saw no warlock mark but there was no mistaking the magic around the boy as demonic magic, it must be hidden.

Still, he wondered how the boy ended up here. Magnus was unable to make portals till later into his life after study magic, maybe it was an accident? Well, no going back to sleep tonight, grabbing a book off the shelf he sat in a chair in front of the couch and waited for the child to wake up.

Nico

He was warm….was he dead? Well, he imagined the underworld as warm with fire and all of that so...yah he may be dead. But he felt comfortable, and he did not think he would feel comfortable in the underworld, so maybe he was not dead. " I see you're waking up "

Nico's dark brown, or some call them back, eyes snapped open….to see cat eyes staring back at him not even a foot from his face. His first thought was monster and he jumped to his feet landing behind the couch. His Demigod instincts winning over anything, and his instincts were yelling at him to simply get away, to put space between himself and the monster. His heart was racing, this was it, a monster found him the ally way and took him here to eat him. Without even thinking, his emotions took over and much like before at camp half blood a crack started forming at his feet and a bone hand starting reaching out of the hole trying to pull itself out. That was until the man in front of him waved his hand and said some odd words and the hand fell back down and the hole closed. " Hey now, calm down I'm not here to hurt you I'm here to help, after all, I'm just the same as you "

Magnus was trying very hard not to show his shock and surprise, a necromancer? Magnus in all his years has never seen, only read about the few warlocks in books that had the ability to do so. To be able to call upon the dead, and have them do as you wish is a very rare ability among warlocks that only those born to hight power demons ever had. Magnus was only able to send the thing away because how much older he was. With a few more years of practices, this boy could be a force to reckon with.

Nico stared at the man in front of him, as most demigods did he learned to listen to his instincts and oddly enough he felt no ill will coming towards him from the Catman thing standing in front of him. " Look, how about we go into my kitchen, and I can get you something eat? You look hungry " the man in front of him was clearly trying to calm him. Nico was about to argue, to book it run but it seemed his stomach made up his mind for him as it growled. After 3 days of not eating he reluctantly nodded his head
