"By ysgramor! Its a dragon!" A man shouted. "Thats not possible!" Another shouted. The two were picked up and torn to shreds by a drsgon. "Fus..... ro dah!" A dragon shouts, destroying the castle walls. "Alright then." The man with green hair said. "Then we kill the dragons." Everyone looked at them with a confused look, and then he charged at the dragons.  All of them then folwed him into batlle. He was at the pinnacle of the empire and the stormcloaks. His name was dio midoriya, a werewolf and vampire. He went by the name and crest  of "The Dragon Thorn". Everyone loved him or feared him. These events took place from before time can tell. After the courages warrior dio had had these battles, the weapon of death reared its ugly head, he fought it. They were both great warroirs, but alduin, the bane of kings, defeated him. Just barely. And then his brother killed the dragon, and absorped its soul, along with a few of the others, however not all of them.   "Dear brother.... we will meet again in Sovngarde." His brother said, closing his eyes. No one was cheering, they had just lost the symbol of peace and hope for them.  They lived on, immortalizing his name in a statue of him, and then they sank into the depths of the world, leaving behind a single thing. The legends sword.  Given to izuku by a scientist who found it and saw his last name on it. Literally. It was s made in the skyforge, with steel strong enough to shatter the sky itself. The power and strentgh has been passed onto a young 4 year old boy named izuku. He also has the sword which, with the correct dragon words, can unlock hidden powers.

A/n: sorry for the  short chapter, but it did what it needed to do.  Izuku's ancestor is the dragon born, izuku gains his own sword, and izuku was born. Plain and simple, but it worked.
