The iron blooded Dragon (Crossover story)

The beginning.

Narrator POV.

Once upon a time there was a great tragedy.

Ten years ago in the city of Fuyuki a great fire burned the city yet from this tragedy hope emerged two children survived the fire. 

As time would have it a great power came into play and thus a holy grail war began seven masters and seven servants, a priest a proud king and the Magus who fought these servants.

That was how it was supposed to go.

<1 minute ago.>

The grail was corrupted 20 years ago and because of this it created the alters who represented the very thing the heroes despised a king turned tyrant and thus the holy grail war changed.

The masters were the first to go once they died the servants disappeared leaving only 3 people to fight for the fate of their world. 

The king in gold, the fake priest and of course the iron blooded Magus fought the alters and after hours of battle the 3 heroes stood tired and beaten a mutual respect between the 3 who realized they were all dying.

"Faker" the king spoke to the Magus who only grunted before speaking back to the dying king "Mongrel" the boy spoke tanned skin and white hair soaked with blood steel eyes looking up at the blonde man with a hole where his heart was.

Suddenly the two laughed and the king faded away and he looked boy who reminded him of crimson archer and laughed "The throne of heroes will wait for you Faker don't let me down" and with that he faded the only thing left of the king was a pile of blood.

"Hey prie-" the boy spoke but saw his empty eyes and he smiled sadly as he looked down at his hands blades coming out his arm and everywhere else he limped towards the edge of a giant pit tears leaked down his facing mixing with the blood.

"Just for once I..." the boy said as he fell to one knee his vision slowly going fuzzy "... I want to save someone" and the boys eyes closed and he fell forward into the abyss and as this happened the universe cracked.

"Hmm? Oh that might be a problem" A voice spoke up in the throne of heroes the King from before watched as the sky in the throne shattered and suddenly  Zelretch appeared before the throne smiling.

"Oh? someone who hasn't died yet is here in the throne of heroes?" The king asked red eyes piercing the intruder "Oh be quiet Gil I have some news regarding your little friend" and Gilgamesh looked at the immortal.

"What's happening with Shirou's brother?" Several voices called out and in response the throne changed slightly into a giant theatre and Zelretch held his arms out "You want to see what is happening with Mr. Emiya? why don't we find out together" He clapped his hands and the lights went out.

<Now>

When the boy fell the grail watched amused wanting to leave the poor fool to fall forever but there were issues that needed to be solved and well the boy made dammed wish so he might as well get it. 

So with the deaths of the holy Grail war the Magus was sent away to the world at the center of the anomalies and then it disappeared leaving an empty cavern littered with bodies and weapons scattered all over the place the only signs of a conflict.

In the dead of night a red star could be seen shooting towards a forest far from most civilization and it's presence marked a new age not bound by the magics of beasts nor the shadow of corruption but instead by the determination of one man.
