Prologue

James Potter was making his 8 months old son, Harry, laugh by conjuring sparks out of his wand. His wife, Lily, was studying upstairs to have her Charms Mastery.

It was 8:30 o' clock, and Lily had made her way downstairs. Smiling warmly at the sweet scene before her eyes, she approached her boys.

"James, it's passed Harry's bedtime."

Looking up, her husband smiled sheepishly. "Sorry, Lily Flower. I'll go put him to bed." Then, winking at her, he added "Maybe afterwards we could share a long, warm bath together?"

Lily couldn't help it. She laughed. Her voice flooded by amusement, she replied "Maybe, maybe not. It'll depend on your abilities to put Harry to bed!"

James laugh fondly. Picking Harry up, he hadn't made two steps towards the stairs that a bright, green light shined through their front door and the windows. Looking outside, James paled. Giving Harry a last hug, and kiss he quickly gave him to Lily, kissed her and said "Lily, take Harry and run, it's Him. I'll hold him back!"

Lily ran upstairs, locking the nursery door with everything she could. The most powerful locking spells, furniture, you name it. She knew herself to be stuck. She knew she would die. She just needed to buy herself time. Putting Harry in his crib, she rolled the carpet on one side, and quickly drew a runic ritual circle. She knew that to activate it she would have to die, and an attempt murderer would have to be done on her son. She made runes to send him to a safe place, as well as a time protection rune, that would protect him until the age of 17. Putting the carpet back on, like if she hadn't done anything. Turning to Harry, she told him how much she loved him.

Hearing James' body hit the floor, and Voldemort slowly climbing the stairs, she knew what she had to do. And she hated it.

Turning her back to Harry when the door burst open, Lily begged for her son's life to be spared, and hers to be taken instead.

Her last thoughts were that at least, her sweet son would be safe. Then, her body hit the ground, and Voldemort turned his wand to the now crying child. He pronounced the Killing Curse for the third time that evening.

The runes made the spell rebound to its caster, leaving only the Sowilo rune on the poor boy's forehead.

Then, the boy disappeared, exactly at the same time that Voldemort's body was destroyed.


Albus Dumbledore arrived, intending on making Harry Potter a great celebrity, to heighten his own fame, which was slowly fading.

He was more than displeased to see that that girl hadn't even wrote the time protection rune properly. Instead, she had wrote a time travelling rune. He would still make a celebrity out of Harry Potter. But he would find a way to bring him back.


On a small island called Berk, in 1894 BC, in the middle of the village, a small child appeared, crying. The rune Sowilo was carved into his forehead. The island Chiefs, Stoick and Valka, got there after a crowd had formed.

Seeing as the child clearly was abandoned, and that they could have a child, the Chiefs decided to adopt the small boy, that they named Hiccup Horrendous Haddock the Third.
