Hiccup flopped onto the couch, his hands pulling at his hair furiously. His eyes were closed as he grit his teeth, trying not to scream. Unintentionally, his memories came flooding at him, and he had no means of stopping them…

...

Hiccup was only seventeen. He and his brother, Toothless, were walking through their town very late at night. Suddenly, they heard a light laugh, and Toothless was thrown on the ground, something pinning him there. Hiccup let out a yell and tried to tear the something off his big brother. It only earned Hiccup an elbow to the face, throwing him back with a force he didn't think possible.

Toothless was screaming out in pain. Hiccup had to help. The something was a someone, and its teeth were biting Toothless' neck.

"Stop!" Hiccup gasped. "Stop! Please! I'll do anything! Please!" His slight gasp became a yell, causing the person on top of his brother to actually pay attention to him.

"Anything?" The person asked. Blood was dribbling out from his mouth. Vampire, Hiccup thought suddenly. He had heard stories, but he never thought that they were true. Toothless wimpered in pain, and Hiccup made his resolve.

"Anything. Just leave my brother alone." Hiccup said quietly.

"Hiccup…" Toothless gurgled.

"Well, I needed a pair of new recruits anyways." The person shrugged. The person stood up, grabbed Hiccup's wrist, and pulled him to his feet. Hiccup didn't know what was going on, and Toothless was in pain. He needed to help him!

The person pulled the collar of his tunic down, revealing Hiccup's collarbone and somewhat of his chest. The person leaned down, and seemingly kissed Hiccup's collarbone passionately. But in reality, the person bit Hiccup. Hiccup gasped, the bite didn't really hurt, but there was something under that that made Hiccup cry out once in pain.

The person pulled away, a deadly smile on their face. "Welcome to the world of vampires." They said.

"What… what about my brother?" Hiccup said, falling on his knees and clutching his collarbone.

"Hiccup?" Toothless asked. "Are you okay?"

Toothless looked different. He suddenly seemed a lot paler than usual, and his green eyes had a sharper quality to them. He also looked stronger and leaner than when Hiccup last saw him.

"I'm… fine." Hiccup gasped, another wave of pain washing over him. His eyes closed at the pain. When he opened them again, his eyes were a light green, his hair had a more lustrous quality to it, and his freckles stood out sharply against his now-pale skin.

"Good luck, vamplings." The person said. "You'll need it." With that, the person left.

Years later, Hiccup was sitting on a dirt road of a provincial town. His eyes were furrowed, his knees pulled close to his chest, his chin resting on his knees. The others in his cult were killing again, and Hiccup was sick of it. They would call Hiccup soft, but Hiccup thought that this was morally wrong. Everyone they killed were innocent people, people with futures and lives and everything to look forward to in the world. Those people had everything Hiccup wanted and couldn't have. Hiccup envied them, to a certain extent, but he felt that killing them was wrong.

Hiccup would try to kill the old when they arrived in a town. They had lived their lives, they were happy, they were awaiting death. But it made him feel guilty nonetheless. So now he was sitting there, trying to block out women's screams and the children's cries. Hiccup knew that there would be no survivors, no new recruits.

Toothless walked over to his frowning little brother. He took a seat next to him, and the corners of his mouth and teeth stained with the deep color of blood that made Hiccup's stomach churn.

"What is the matter, little brother?" Toothless asked. "You have been acting strange lately."

"I don't like this." Hiccup answered. This was the first time that he actually answered that question truthfully.

"What do you mean?" Toothless asked again, not understanding. "I do keep telling you that you will get sick off those old people's blood one day."

"It is not that, Toothless." Hiccup said, apprehensively. "I hate this, how we kill all these people…"

"What are you talking about? This is how life is, Hiccup. They live, we kill, we drink, and we live. That is how the world goes."

"We could change all that, we don't have to kill people…" Hiccup said, but he could sense the outrage in Toothless' voice. He shouldn't have said anything. He should have kept his mouth shut.

"Why do you have to question things?" Toothless replied, anger tangible in the air. "Nothing will change! This is how life is!"

"Why do you have to be so mindless? Don't you see the people you kill? Don't you see the possibilities they have that we don't? Don't you see the life leak out of their eyes when you attack them?" Hiccup quipped back.

"We are supposed to find that enjoyable!" Toothless said, commenting on Hiccup's last question. "The life draining out of their eyes, only to leak into ours…"

"Well, it is not right! It is cruel and disgusting!" Hiccup yelled.

"You are a vampire!" Toothless growled.

"Maybe I do not want to be a vampire anymore!" Hiccup growled back.

"That's like saying you do not want to be my brother. You cannot escape the facts!" Toothless said.

"Well, maybe I do not want to be your brother, if this is what that means." Hiccup said, gesturing at the death and destruction that surrounded them.

"Well, go then! If you want to imagine that you are not a vampire, then you are not my brother! Not anymore!" Toothless said. With that, Hiccup stood, spat at Toothless' feet, and growled at his former brother.

"No longer am I your brother, and no longer are you my kin, may we stay out of each other's lives, as long as we both shall live." Hiccup recited, looking at Toothless with a hard glare. And with that, Hiccup sped off, running away from the pain he was feeling.

Hiccup knew that he couldn't stop being a vampire, but he thought that his brother would be there for his forever, like they said so long ago. But now, it was a lie. All a lie, and in that instant Hiccup realized that nothing lasted forever.

Hiccup had all this life to think about things, but he knew what he was going to do. He was going to protect the good people out there, who had futures and lives and families and jobs, because if he couldn't do it for himself, well dammit, he was going to do it for others.

...

Hiccup came back to reality with a quick and electrifying jolt. His fingers untangled out of his hair and he was breathing hard, although he didn't really have to breathe. He was also shaking.

No longer am I your brother…

Hiccup sat up and paced the floor. Toothless swore to never interfere with his life again, why was he really coming to him now?

And no longer are you my kin…

Hiccup's head was swimming, and the sun was starting to rise.

May we stay out of each other's lives…

Hiccup threw open his door and walked out, slowly making his way to Jack's house. He needed some time to think and calm down his nerves.

For as long as we both shall live.

Hiccup meant the oath his told Toothless, why didn't Toothless?

Hi guys, so I just wanted to hop right into this. Little backstory there. Does it all make sense now? I hope it does.

Leave me a review! Tell me what you want to see in this story, because I have an idea, but everything is welcome (everything but smut!)

Thanks!
