If you have read the books and seen the movies this book will not make sense unless you read this. I had combined the books and movies into one.
So here's what happened in my crazy crossover!
Loki had made a deal with Bertha the leader of the Bog Begler trib that he would give them all the gold ships and treasure they could ever dream of, so Bertha agreed to know that she was already one month pregnant and that she could get the gold without having to have another child. Eight months later Bertha gave birth to Camicazi but one month later she also gave birth to another child. Scenes Vikings knew nothing about superfetation pregnancy Bertha assumed that this child must be Loiks and that she could be a danger to her tribe. So what did she do? Sailed over to Berk at the dead of night and draped the child off at the doorstep of some random house (which just so happened to be the Hofferson's house ) Beter the Hogleins then the Bog Beglers. The child was taken in and raised as if she were their own.
Hiccup the First and Hiccup the Second had made peace with the dragons before but they still never got to ride one, but after they died and their dragons were locked away and Dragonses baned, people and dragons started to avoid each other, they weren't at war and they weren't at peace. One day just after Hicup was born a few dragons attacked taking his mother with them, that was the first and last dragon attack in years. Hiccup Fishlegs and Amelia ( My OC) grew up together and became very close, Amelia and Hiccup learned to speak Dragonese in secret. When they came of age they joined the pirate training program(The toothless that was in the books never happened, sorry).
The rest of the sorry went on as normal the three friends meet Alive and defeat him before meeting Camicazi and becoming four. Hiccup and Amelia had gotten the Slave mark and were exiled from their tribs after the sword fighting contest, and Alive got all the lost things(There were only nine seines like I said no Toothless).
Alive and his wicked mother then started insulting people and dragons like well the dragon rebellion grew stronger.
When Sontlout went to fight Hiccup he waren a suit made out of dragon scales under his fire suit, well he knew Hiccup wouldn't be as good a sword fighter without his left arm working he had seen Hiccup come close to death and pulled through he wasn't going to take the chances that hiccup could win the fight. After he and Hiccup were on good terms and Snotlout came up with the plan to stop Alive and the Alives men Hiccup agreed to swap close but not the armor. Well, Snotlout was shot and set on fire the dragon scales kept him alive.
After Hiccup became Knig of the wilder west he set all the dragons and slaves free but then said that he was still too young to be Knig and that he would take up the crown again when he also becomes the Chiff of Berk.
After this everyone went back to their normal lives. Mostly. Some of the dragons still were attacking, there weren't enough of them to cause a lot of harm but there were enough to stop all tried and blood feuds, from happening, the pirate training program then started teaching how to kill dragons, and that this must be down on sight.
Within the year Fishlegs had a growth spurt and got to hang out with the cool kids leaving Amelia and Hiccup alone most of the time, in this year Hiccup had started to have a crush on Amelia's older sister. Then one day Hiccup and Amelia had shut down two dragons and went looking for them. This is where we leave off with the story of how Hiccup meets Thoothels how Amelia Lavnder, how Hiccup finally gets a girlfriend loses a leg, and makes peace with the dragons.
