Prologue

A long time ago there were three kingdoms. These kingdoms were always seen as rivals towards one another, until one day the rules of each kingdom decided that they have had enough of these petty bickering and decided to unite all three kingdoms into one. Once united the one new nation had changed the world with their now advanced technology and powerful magic to bring peace under one rule. But like all good things they always come to an end by the death and betrayal within the royal family, which led to a series of events ending the world and those who had survived were left in what once a world of peace and prosperity was now a dystopian wasteland filled with death and destruction. But all hope is not lost for our story begins with a young man who's destined to change the future.

In the middle nowhere there a faint music playing (the song that plays is ITS ALL OVER BUT THE CRING) that leads to a crater and inside the crater there is hiccup working on some sort of machine, "okay just gotta make a few tweeks here aaaannnd. OUCH!" he yells after smashing his finger.

"so how's it coming?" a voice asked; "almost done just fixing few thing here then it will be ready for the trip" hiccup responded while trying shake the pain away. " but I still don't get why you can't come as well Mr. Peabody" hiccup asked while getting back to work. The other guy who is now known as Mr. Peabody sighs "I told before there can't be two of me in the past. It can cause a major paradox that can make matters even worse than they are."

"cant get any worse then this" hiccup whispered to himself, "and there we are, everything's all done." Hiccup finished the final adjustments than pushed a button on the machine that opened a hatch door. Mr. Peabody smiled "good work hiccup" said Mr. Peabody as patted hiccup's back "finally we have chance to change the past and prevent this future." Hiccup started gathering some stuff in a bag "so how far back am I going?" "you should arrive only a couple of years after the three kingdoms' united, and once there convince the past me to help you with what you really need to do."

"so about that I get it that I need to protect the 4 people and 2 of them I only know what you told me; the cryo-mancer and her sister but I don't what they look like how will I know who they are?" hiccup asked as he finished gathering his belongings than proceeded to step inside the time machine "Im sorry hiccup, I wish I can help you there but due to many years of surviving the wastelands I lost a lot of my past memories." Hiccup put his head down and sighed then looked back at "so this is than huh" "so it is" responded and proceeded to give hiccup a goodbye hug the same with hiccup.

"Goodbye Mr. Peabody" hiccup said as they broke out of their hug, "goodbye hiccup and good luck with everything make sure to this future from happening by any means necessary" hiccup only nodded and was about to turn on the time machine until Mr. Peabody interrupted him " oh and hiccup once your there can you do me one favor…. Watch over Sherman please." Hiccup smiled "I promise" than he pushed a button that closed the hatch door and the machine began to activate. Hearing the engines starting to run Mr. Peabody got out of the way as a ball of energy surrounded the time machine and a bright flash the machine had vanished; Mr. Peabody stood where the time machine once was "good luck hiccup, may fortune favor the foolish."
