Taken, forgotten

Chapter 1)

*Valka's P.O.V.*
The dragon raid horn went off, I put Hiccup in his cot and then ran outside to stop the Vikings killing the dragons, at about 20 minutes into the raid, a dragon no one has ever seen before went into our house, I ran to the house, when I got in I got a sword and saw him play with Hiccup, I dropped the sword and looked, then a axe came flying at the dragon, I jumped forwards to get Hiccup, but it grabbed Hiccup with it's claws and flew away, Stoick then said "I knew he wouldn't last 1 week!" He then turned around and ran back outside to carry on fighting. I just sat there crying.
*9 months later*
*CloudJumper's P.O.V.*
Leroy (the Great bewilder beast) had told me that the terrible terror scouts had said that the Chief of Berk has a child that is considered 'weak', 'worthless' and 'won't last a week' so Leroy told me to get him, this is because their blind 321 year old fortune teller said that a Chief of a strong tribe will have a 'weak' and 'worthless' child that will keep peace in between the Vikings and dragons.
When I split from the queen's attack squad 157 I then flew to our home. When I got there I put him in a cave, the one that we've been preparing for 20 years for this, so there was tools and other things to help him (there were simple forgery items like a hammer, anvil, that thing that you heat up metal with that I forgot the name of, water bucket, sharpener, coal, and a book on forgery, leather, sewing equipment, a book on that, a book on how to speak Norse , and some clothes for him. Leroy had said to name him Levi, this is because he is connected to both Dragons and Vikings (Levi as a name in Norse is 'Connected').
*Stoick's P.O.V.*
I had told Valka that he wouldn't last a week and guess what? He didn't even last 5 days... We have another son now, about 4 months younger then the others this year, he was born in November, 3 weeks ago, he looked strong and powerful, so I named him Leonidas (Norse name for 'strong as a lion') we have rebuilt our house and we have told the whole tribe to never tell Leonidas that he had an older brother. We have also built up our defences to protect the village more.
*9 years later*
*Hiccup's P.O.V.*
I am now 10, I know how to speak Dragonese, Norse, Latin, and about 5 other languages, I have a night fury as my dragon, his name is Toothless, we have mapped a lot of the world, I call the large island to the west Greenland, south west is Iceland, east is Scandinavia, but I rarely go there because of the Vikings, to the south is the southern archipelago (British Isles) and south east is Europe, where lots of tribes live and an empire called the Roman Empire, I've only been once, but I didn't get to find much (he only saw the area where Belgium, the Netherlands and the very top of France are as well as all of the east coast of England). I have tried to help Tribes to stop them from killing dragons, but nothing has worked, yet.
*Astrid's P.O.V.*
The dragon raid horn went off, I charged outside and I hit about 35 terrible terrors, then I got my first Nader, then we all heard,a loud screeching sound and that must be..."NIGHT FURY, GET DOWN!!" Someone shouted that and we all took cover, the night fury hit all of the main defences, then people started shooting bolas at it, one hit it, it then fell in the woods, then I and others ran to kill it, when we got there in a couple minutes, we found the bolas, but cut, and there was a sword, I picked it up and I felt it, it was light, then I said "it's light, most likely weak..." 20 Vikings surrounded it and then I gave it to a Viking to hold, he held it and I smashed my axe into the sword, my axe broke and the sword was undamaged, but how?
