The Chosen Ones

Epilogue

It all begins when three worlds collide to go against one big force. Will they all come together in peace? Or will it just end in disaster? The world of Nephilim always trying to protect the world filled with demons, and of course Valentine Morgenstern. And then of course the demigods with the famous "Big Three" that is of course, Zeus, Poseidon, and Hades. They all hated each other at some point in time, mainly Hades though. They put it onto themselves to make it to where they were never supposed to have children with humans, but they all did not follow that rule. Then the famous wizards and witches of the world. How could I ever forget about them? Always Voldermort posing a threat to them, but what if the three all teamed up, knowing about each other and what each person can do? This shall be interesting.

Chapter 1

Clary

I sighed, wondering why Magnus was telling them to come to his place. I honestly did not want to be here. I looked over at Jace seeing his concerned expression. We both were stressed by Valentine, and then finding out Jonathan was my brother, and Jace was actually Stephen Herondale's son. All of this gave me a headache, but at least I could be with Jace. I saw Magnus come into the living room and have a grave expression on his face. "Magnus, what is it?" I ask him filled with concern.

"Well, I am going to have to take you to a certain place." Magnus tells me this with an edge of anger.

"Yes, who needs us now?" Jace says with no concern. He seemed almost annoyed.

"Well I shall be taking you to England. Valentine has apparently partnered with two other people, and they are rather powerful people also. A man named Voldermort, and a man named Hades." Magnus tells us, looking down at his cup. He looked tired lately, probably trying to find some way to be with Alec, and then all of this Valentine stuff drains him somewhat. He still looks like Magnus, as always fantastic looking, and glittery.

"What?" I suddenly stand alarmed by this new information. Jace looks at me, his expression surprised and as alarmed as mine, maybe even more so.

"Yes, he has made some sort of contract and they are helping each other out." Magnus speaks with some fury behind it, his eyes grow dark. I notice even Magnus is not liking this.

"Isn't Hades the Greek God of Death?" Jace asks, hoping to not anger Magnus somehow. Magnus looks at him and smiles somewhat and his eyes still very dark.

"Yes he is, he is one of the 'Big Three' as the demigods say, and Voldermort is just a very powerful and evil as Valentine himself. Along with Hades, but he is only doing it for the souls I presume." Magnus states in a matter-of-fact tone.

"Well, am I going to have to make a portal, or will you?" I ask Magnus while putting my hand down my pocket to get my stele out.

"No, it's better if I do it. Mainly because I know England better then you do my dear." Magnus begins to speak an unknowing language. I look towards Jace and walk over next to him and squeeze his hand.

"Don't worry, this will be done… soon." I look up at Jace's golden eyes, hoping he'll look down at mine.

"I hope it will, I just want Valentine gone." I saw anger start to flood his face as he says this. "Don't you have to talk to Luke about you going to England?" He looks down with a look of 'You better do it'. I sigh and look down at my phone.

"Fine. It might as well be better to do it then to not to…" I call Luke up hoping he will pick up.

"Hello?" I hear Luke's familiar voice.

"Hey, I need to ask you something, and probably Mom." I tell him hoping he will say yes.

"Yes Clary, what is it?" He said this cheerfully, almost to cheerfully even though what I was about to tell him might just upset him.

I begin to tell him why I need to go to England, and he obediently listens.

"You can go, but I will be going with you, whether you like it or not. Neither me or your Mom wants you to die. Not at your age." He states this with anger in his voice, I wanted to say no but I knew he would find a way to still see me and make sure I was okay.

"Magnus is making a portal. So get here so he can make one for you also." Luke says yes to me and hangs up, I tell Magnus to expect my Mom and Luke. Me and Jace go through the portal expecting to feel very warm, but instead it was really dark and cold. My teeth began to chatter by the impact.

"Want me to make you warm?" Jace winks at me and I feel like pushing him through a window.

"No… it's okay. It's just really cold, why is it so cold?" I look up at him as we appear on a street in the middle of a town. It wasn't big but it wasn't small either. And there was people everywhere.

"I knew I should've brought a heavier jacket…" Jace frowns then hugs me to make each other warm.

Harry

I look down at my watch wondering where Dumbledore went off too. I began to think of Ginny wondering what she was up to; I hear footsteps began to come up the stairs towards Dumbledore's office and I soon see the door open and see the long beard and wise eyes of a powerful wizard.

"Why hello Harry, I see you stayed. Sorry to keep you waiting, something came up."

"What was it?" I ask still wondering what he had to tell me.

"Well, this is something I still needed to tell you before, remember when I was about to tell you about different forces going throughout our world." He looks at me while sitting down behind his grand desk.

"Yes, I remember that, what is it?" I sit back wondering who else could there be besides the magical creatures in our world, among us and humans.

"Well, there are two other kinds of races among this world and ours. Even though they don't go to this school or anything like that." He looks down at his drink and fills it back up, "These races of beings are the Nephilim or Shadowhunters, and Demigods." He says this with seeming like he already knew these races for such a long time, and just never spoke of anything about it. Maybe he has and none of us never knew.

"And what are they exactly? I know what demigods are, but what are Shadowhunters?" I ask him as I begin to think of a bunch of hunters killing whatever they kill.

"Shadowhunters are people that have angel blood as long as human blood in them. So they are not your usual humans. You will find out more when you meet them, as long as with the demigods. We have all heard the stories, but never met one." He smiles at me.

"When shall I meet them professor?" I begin to wonder what they all look like.

"In just about thirty minutes or so, we should begin to head towards Hogsmeade soon." He gets up and starts to walk to the door.

"Now the reason why I am having you meet these people is because they all have the similar evils, the Shadowhunters have a man named Valentine who seems to have allied with Voldermort and the god Hades." I shuddered after he said this.

"Why did he do this? Do you know?" I start to become concerned. I wish Voldermort could just go away, but he seems to stay alive.

"We shall soon find that out."

Percy

I hear Chiron yell out my name and I look towards the fighting arena.

"Hello Percy. We need to talk… privately." He looks around. He seemed alarmed when he said this so I follow him.

"What is it Chiron?" I look up at him.

"Well, something horrible may happen. And it may happen soon. With two other people you have never heard of, are going to be in alliance with… Hades…" He looks at me and his eyes darken. I hear the ground slightly rumble. I roll my eyes thinking about my adventure down there, than slightly shuddered.

"Who is he becoming ally's with?" I start to become alarmed hoping we will not have another war, but I wouldn't be surprised if it happens again.

"A man named Voldermort and Valentine. They are as evil as it gets, at least that is what I have come to understand." He looks out across the river.

"Well, when shall I go against these guys?" I start to tap my toe against the ground, beginning to make some song appear in my head.

"Well you shall be meeting people to go against them. Witch and Wizard that are in England, and Shadowhunters that live in Manhattan."

"What are 'Shadowhunters'?" I ask confused by this. What do they hunt? Rabbits, probably. I would be amused by this.

"They are people who have angel blood in their veins, along with human blood also."

"I have never thought angels even existed." I become curious of these hunters, what do they hunt then?

"Oh they do, just not among us." He looks back at me, the look in his eyes is as if he was scared for me, "I shall be taking you to England. Or well, Hermes shall help." I looked up at him surprised and he was almost as surprised as much as I was. 'Here we go…' I thought to myself.
