World creator system

A great winter that lasts a generation descends on the world, followed by a night that goes for years.

The leaders of the first men at the time received vision of the Night King and the destruction he would bring to westeros.So they joined forces tower Children of Forest and giants.There were green seers and wargs that joined the war.

Eru was watching everything and he decided to help them out with an extra help, he fashioned a giant wolf with his powers.He had plans to sent this fellow when the time is right.

While under the cover of darkness, the White Walkers invade Westeros from the uttermost north.

But due to warning they were able to fight off the first wave, but it still caused immense suffering and destruction.

At the time Azor was readying for next battle, but needed a powerful sword to fight the night walkers and Night King.

He labored for thirty days and thirty nights until it was done. However, when he went to temper it in water, the sword broke. He was not one to give up easily, so he started over.

The second time he took fifty days and fifty nights to make the sword, even better than the first. To temper it this time, he captured a lion and drove the sword into its heart, but once more the steel shattered.

The third time, with a heavy heart, he knew there was visions from so called Lord of Light that he had to get the sword he had sacrifice his beloved wife.

But then he saw transparent ghost like figure stating by the window, he recognized the figure as Eru immediately because of the statues all around Westeros.

Azor quickly bowed"My Lord."

Eru had sad smile and asked"You don't have to sacrifice anyone for the sword, if you did R'hllor would not only had your wife's would.But yours too...he would have used these souls to empower himself.Which would mean her soul would never be able to rest."

Azor was in shock and was scared of the fact he almost sacrificed his beloved wives soul to such monster.

Azor was in tears, while Eru spoke up"Show me that sword."

Azor did as he was told, Eru waved his hand over sword which began to glow and morp into a beautiful and majest blade.

It a hand-and-a-half sword with a curved cross-guard and a slightly longer hilt than usual. 

The glyph for "fire" in the Ancient Language, "Brisingr", was engraved on both the blade and the scabbard. It had a dark blue scabbard, with a leaf-shaped steel cap on the end of the scabbard.

The blade itself was a lighter iridescent blue and contained cable-like patterns within it, as well as a flame-like pattern marked the transition between the soft spine of the blade and its hard edges. The guard was made from blued brightsteel.The grip was made from black hardwood. Lastly, there was a large blue sapphire in the pommel held in place by four ribs, which looked like claws, made from blued brightsteel.

It was really Brisingr, while Azor looked at blade in awe and Eru explained "This is Brisingr,Whenever you say the name, the sword burst into a blue flame.It will help you defeat the white walkers."

Azor bowed and was grateful and he watched Eru disperses into thin air.

Also he knew Azor was going to have future relations with Brandon Stark.Who would become his right hand and marry Azor's daughter.

Brandon Stark was not the only who was also gifted in magic.There was Garth Greenhand, who an oldman he was the ancestor of Gardners and his son Garth the Gardner would later be taught by the children of the forest.

There multiple heroes during this war like

Durran, called Durran Godsgrief, was the mythic first Storm King and the founder of House Durrandon...etc.

But for Eru the figures like Brandon Stark, Garth Greenhand and his son Garth the Gardner we're interesting ones.Since Greenhand was old and couldn't fight in the war, he instead went the route of a healer to help the injured and his son was also not a figher, but helped everyone by providing food and helping as much as possible.

While the rest of first men, Giants and children were readying themselves for the next wave.

They knew more would come since they were not able to kill the Night King last time.So they all prayed to Eru, Yavanna and Ulmo.That's when they hard huge growl and menacing voice.

"Humans, I have come to help you in your endeavor to kill the Night King by Lord,Eru Ilúvatar." The owner of the voice was a huge wolf with such lustrous silver coat with both his hands and feet dyed red with a luminous effect.It was radiating such a divine aura that it was ridiculous to even compare it to direwolves or even whitewalkers they had seen up until now.

Everyone froze. They didn't even quiver, but they felt slight relief hearing this massive wolf was sent by Lord Eru.

This gave everyone more hope, while Leaf with low tone questioned"Ohh mighty wolf, what is your name."

The wolf answered"Fenris."

They simply bowed, while the war began with the white walkers.The arrows made from dragon glass rained on the white walkers and Azor using his flaming sword started cutting through the white walkers easily.

All of the first men, Giants and Children of forest could feel that they were not getting tried nor was the cold affecting them and added fact was they felt they strength had been boosted.

Azor felt excitement and happiness as he yelled"Our creator has blessed us,so fight with everything you have."

The army was now fully invigorated and with roar they rushed to fight the white walkers, who were completely shocked.

They were even also taken by surprise seeing giant wolf enter the battle field.

It ripped through the wights and white walkers easily.Also Night King at present was not as experienced in battles and nor did have full control over his ice magic.

So only thing he could do was retreat, which he did successfully.But barely, he had to sacrifice majority of his army to escape at the time.

But internally he vowed to come back for revenge.
