Thousands of years before the age of heroes happened. There was a comet the fell to the ground in westeros. From the impact zone a tree sprouted. The tree had an energy that the sorcerers , heros ,and even the remnents of the empire of dawn could not comprehend.
the tree was forgotten but it grew still along with a massive forest around it. Trees hundreds of feet tall and dozens of feet in diameter. The forest spanned hundreds of miles in each direction. In the location of the kingswood. No matter the attempt they could not be felled ,neither flame nor steel could harm them. The forest became a forbidden zone for people of the world. The people Thought it was a dark sorcery that saved these trees or A place the old gods did not want tresspassed.
This place remained the same for thousands of years. Then the age of heroes came around and even their mighty magics could do nothing to this forest from the top or the sides. It was completely isolated for thousands of years until one fateful day that the long night came.
The main tree in the center of the kingswood sprouted a fruit. The outer trees of the forest withered and died alowing access. When explored no one returned. The forest was thought to be marked by death. The heroes of the time Bran the builder and azor ahai contemplated checking it out.
Azor ahai finished his tasks of dealing with the others and the night king, depressed about sacrificing his love. Bran the builder having finished building the wall. They traveled to the southern kingdoms. Heard the stories of the forest.
They decided to enter and when they did they were met with a nightmare far worse then the night king. They saw a woman standing in the crater at the center she had ears like a rabbit and 2 dots on her forhead. She was stunningly beautiful, with white pupiless eyes. She was tall ,and graceful. She had both men entranced. Her name was kaguya otsutsuki.
The men fell in love with her at first sight. Her charm was undeniable. And she being a naive women fell for them as well. She kept her powers hidden from the two men As they lived together. she knew she was stronger then anything in this world especially after eating the Chakra fruit. but she kept her life a secret. And they lived together for many years she helped extend there lives with her powers.
She first gave birth to azor ahais child a white haired boy with similar features to the mother he was named belarys after a god. Next was the birth of her second son from bran the builder the child had the same features as the mother as well and was name alarys.
The two boys had the blood of the mother and her Chakra as well but she never explained it to them she thought it would keep them safe. They traveled the world and met many people and unknowingly shared Chakra with them. Spreading Chakra far and wide.
The mother got pissed at this and wanted to kill all who had chakra but her and her boys and collect the Chakra that she claimed was stolen from her.
There was a massive fight in the indestructible forest azor and bran had taught the boys magic and runes of this world. They had also given their lives in the fight between mother and sonsthe felt betrayed by the woman the loved. The boys also realized the power they had hidden deep in their bodies.
They secretly trained the ways of Chakra and after many years of fighting they finally defeated the mother after belarys found that nature energy was compatible and added an enhancement to Chakra. They sealed her away in a series of volcanos across the sea.
The youngest alarys stayed to watch over their mother as he had always loved her,as the older brother traveled the world and fell in love and had two children. They settled in the northfor a while the second son was named Alaric. belarys gave him the surname stark and helped him become the king of winter discretely with his powers.
The first son named azerys wanted to go to the place his uncle was. They traveled to the volcanic peninsula where the balerys gave the son his name as a surname and helped him claim the peninsula as his domain.
The brothers never told the boys of there powers and what flows in ther blood. They passed after 100 years a remnent of kaguyas blood.
The belarys family split and created 40 families who ruled the peninsula together and conquered many lands Do to their blood allowing them to tame dragons. Which came to the peninsula sometime after thousands of years after the original families birth.
The boy alaric in the north started his family and rules for many years fought rebellious and strove to be feared and loved for the honor and the creatures of the north that they were able to tame. The direwolves becoming there house sigil. There reign lasting thousands of years and continues still. Not aware of the distant relation at this point with the valyrians.
The starks looks changed drastically after the many years of marrying outside the family. Some in the family lost the white pupilless eyes for a gray eye color some with and some without the pupils also they no longer sport the silvery white hair of there ancestors.
The valyrians were similar but kept the hair. There eye color changed to purple some gaining the pupils some not. The ones who did not were royalty. The purest of there lineage.
The people of this time were unaware of the Chakra in there blood as for 8000 years it was spreading throughout the world.

The catastrophe.
The doom of valyria struck hard people called it retribution for the cruel and disturbing magics the valyrians used. The reality of the situation was kaguya broke her seal but in the process of releasing that massive amount of Chakra and energy she died along with her youngest son who sealed himself with her due to the love he still had for her.
This destroyed the land and ripped the peninsula apart killing the majority of the valyrian dragon lord families and there dragons.
There was only one dragon lord family to survive completely. They are the targaryens one of the 40 families who ruled valyria however on the lower side in status. It wasnt always this way though as the second belarys son was a targeryen. But after 5000 years they lost positioning in the freehold. Due to this There family was not the purist and some members had pupils in ther purple eyes.
The family fled as one of the daughters foresaw the doom in a prophetic dream one hundred years prior. The patriarch of the family listened and they traveled to an island volcano off the eastern coast of westeros. They became a noble family and named the the island dragonstone. There sigil a three headed red dragon on a black background.
After a hundred years the dragon lords grew restless. Sick of the fighting between the man kings on the mainland the patriarch aegon and his two sister wives laid conquest to westeros with three massive dragons.
Balerion meraxes and vaghar.
They claimed the seven kindoms of westeros the targeryens ruled for 130 years with dragons and then almost another 170 after they died out due to infighting ,a war and plotting.
Around 280 after aegons qonquest a rebellion started after a targeryen prince was accused of kidnapping a stark woman which did not happen they married for love and the child a true born. However she was already betrothed to another.
The king was going insane after being kidnapped and tortured a bit himself. And killed the stark lord and his heir. Cuasing the realm of westeros to rebel. It was a bloody war. And the targeryens lost.
Eddard stark still convinced his sister was alive traveled to dorne. Trying to rescue her only to find her dying from child birth. The child was a mix of targeryen and stark blood.
The first time the blood has been united in 8000 years. No matter how diluted, it was there.
