Timeline is a bit modified.
King Brandon 'The Builder' Stark, the first of his name, King of the First Men, King of Winterfell, stood atop a hill watching his greatest creation being built. The Long Night had just ended. He had lived his entire life in the longest winter in the history of the world, lasting for 500 years. With the Long Night fading away so too had the White Walkers. He himself had killed more the hundreds of White Walkers with his bronze blade enchanted by the Children of the Forest.
They came to us just before the long night. They explained to us that these abominations were created to stop the First Men's advance into Westeros. But soon after its creation the Pact was signed. They attempted to contain these creatures, in the far frozen north of the land of always winter. They had succeeded for 4000 years, but as time went by they grew smarter more powerful. Using the dead bodies of the first men and animals, they had created more White Walkers, and skeletal creatures known as the came down to warn the First Men about these abominations and a powerful house known as house Stark, took these warnings and rallied their bannermen. House Umber, house Mormont, house Cerwyn, and house Reed. They too had brought their own bannermen. With this force of 10,000 men they fought the White Walkers, with the Children of the Forest, the Giants. They forced the White Walkers back and now King Brandon Stark is building the wall to forever hold against the White Walkers.
King Brandon Stark realized there will be other First Men Clans on the other side of the wall so he sent his rangers to collect all the clans, and the giants and bring them to him four moons ago, and they have all slowly come further south, across the almost finished wall. The different clans came to him and swore fealty. House Thenn was formed. Soon followed by house Iceriver, house Giantsbane, house Beasthhorn, house Hornfoots, house Whitetree, and house Frost. The giants formed the house Giantarm, under the Magnar of Lun the Wise.
The giants brought their massive mammoths. They herded and cared for mammoths, and mammoths were a great boon to house Stark. They had a lot of meat, fat, and fur. They could be used as living war machines or a strong workforce. Allowing the northerners to move around great weights with ease. The Children taught the First Men how to become a warg, and how to become a greenseer. King Brandon seemed to be particularly gifted in this area. And with this change, the North would become the strongest region of Westeros.
Winterfell is a mighty fortress. Winterfell is a huge castle complex spanning many acres and protected by two massive walls. The walls is tall and thick enough to withstand the giants. There is a fast growing town outside, the winter town. Winterfell was built around an ancient godswood and over natural hot springs. The Godswood was as old as Westeros, and it houses the Children. It has one massive Weirwood tree taller far vaster and taller than 10 giants, and many smaller Weirwoods. The water from the hot springs is piped through walls and chambers to heat them, making Winterfell more comfortable than other castles during the harsh northern winters.
Inside the walls, the complex is composed of many dozens of courtyards, few gardens and large open spaces. Weapons training and practice take place in those yards. The inner ward is a second, much more open space in the castle where archery practice takes place. It is located next to the Frost tower. Inside Winterfell stands the inner castle, which contains the Great Keep and the Great Hall. The Great hall was big enough to house around 10 dozen giants, and 10,000 men. The Great Keep was the most beautiful and effective keep in all of Westeros. It was not beautiful because of lavish decorations and artwork, but because of a simple stark beauty. Like a winter rose.
King Brandon Stark sat on his upon his throne, which was another marvelous thing. Made from Ironwood, and Weirwood, the throne had many wolves snarling on it. In all different colors, white, grey black brown. His crown upon his brown, a crown of swords made of bronze. He was 53 name days old and he knew that he had naught much time to live. His heir Rickard Stark had his father's looks. Tall with brown hair, grey eyes, high cheekbones, and a long face. He was a very skilled swordsman. He wielded a great sword made of enchanted bronze. He trained daily, fighting many guards and other warriors, many time fighting multiple enemies.
The Crowned Prince Rickard was a strong fighter, war-time leader and a strategist, but he was not the greatest at negotiations, and running a country on a daily basis. But his younger brother Prince Torrhen was a skilled fighter preferring the dual wielding style. An unusual one, but he is very proficient at it. Not nearly the best but good enough to have a decent chance in a battle. But his skill was in the diplomacy, economics, ruling the small folk, and running the country.
Together they formed a great team, allowing each other to flourish in their respected area. Prince Rickard fought with the standing army, fighting back barbarians, and bandits. He gained a reputation as the Strong Wolf. While his younger brother slowly took control of the finances from his father, and nearly doubling the amount of money being raised by house Stark.
On King Brandon's death bed, he looked upon his two sons and said "My child, you will have many enemies in your future in uniting the the North and the Neck. But together, and only together will you be able to accomplish such a dream. Only together will you beat the Red Kings, and control the North. I see a great future for house Stark, and you must make your mark." and with those words, the first King of Winter, King Brandon "The Builder" Stark died.
It is three years, since the death of the first Winter King. And King Rickard was planning the strike against the Red King.
"My Magnars, the Dreadfort might be strong but we have giants and mammoths unlike them, and house Bolton rely on fear more than actual skill in leadership and fighting. Once they are pushed back they will be forced to retreat into the fort which we can then starve them for a week, afterwards attacking them." said King Rickard.
"That might be true, your grace but to get those men and giants across to the Dreadfort, they will be notified and rally their own bannermen. We must have a plan to destroy those men." said Magnar Umber.
"Brother, he is correct, and I suggest you lead an army to lure the Boltons, to the lonely hill in which another army will be hidden in. The bait army must contain mammoths and giants, or they will never believe that the army is the real deal." said Prince Torrhen.
"I agree, but to make it truly believable, I must lead the charge." said King Rickard.
"Yes, by doing so, they will truly believe you are committing to the army." said Magnar Mormont.
"Very well my Magnars, I believe we have a plan. Magnar Thenn you shall be leading the army within the lonely hills, with the council of Magnar Mormont. Make sure the smaller army is able to get into the lonely hills without getting detected. Magnar Reed I you are far away, but I would like you to prepare your men just in case, but make sure to be loud about it. We want the Red Kings to know that there are more men coming. They will lose moral knowing that we will have back up men. The rest of you, my Magnars shall join me." said King Rickard. "Brother, I need you to remain and rule the north when I am absent."
Scoffing Prince Torrhen says "When am I not?"
With a booming laughter from the group left to gather their men. And King Rickard turned to Prince Torrhen.
"Brother while I am gone the North must be running smoothly. There can be no chance for a rebellion. We will not have the men to deal with it, nor get to back fast enough. You must keep the moral high, and Winter Town happy." said King Rickard.
"Don't worry about that, brother. I have been dealing with these kind of things for a while, you must make sure you come back."
"Very well, we will both keep our promises."
King Rickard road with the bait host, with his greatsword, Ice, strapped across back. It was made of enchanted bronze like his father's weapon. The ambush host in the lonely hill was in position.
He turned around to the Magnars and said "Set up camp here. Slightly closer to the forest then necessary. Make sure that we throw a big feast to make it look like soldiers are drunk. Make sure in the middle of the night they dress in the leather armor and go to the nearest gate way as possible. And they will receive further orders."
"Your grace, may I ask why you are doing this?" asked the Magnar Frost.
"But beating their ambush will lead to a moral boost, give us something to mock the enemies. By mocking them, we will be able to better lure out the Boltons. They are prideful creatures, and if we provoke them they will respond. So when we lead them to the lonely hills they will be annoyed enough to follow us to the hills." said King Rickard.
"Very well your grace,"
"Magnar Umber I would like you to do something very important for me." said King Rickard, and he quickly explained his plan, and explaining Magnar Umber's part.
"I will get my men on it right away."
The Bolton men made their way to the wooden camp walls. They quietly went over the wall, and approached the men guarding the gate and slit their throats. They died before they could even utter a sound. The two assassins, signaled the army to come down to the camp by extinguishing the left torch.
The army quickly but quietly entered the camp going moving to the tents to slay the sleeping men. Most of the army was at the tents ready to sent it on fire, and slay the men and giants as they come out. The Red King's son Ramsay Bolton laughing in glee. Imagining this battle being called the Raping of the Wolves. And being remembered as the leader of the Raping of the Wolves. Hoping to be able to skin and flay Rickard Stark, he gave the signal to start.
With the signal the most of the Bolton army threw the torch on the tent waiting for the men to come out. The few impatent ones just barged in and stabbed and the sleeping form of the man. Till no blood came out, they moved towards the 'dead body' and saw it was not a dead body, it wasn't even alive. It was a dummy. The men realizing that they were in a trap rushed out of the tent to warn the men.
"IT'S A TRAP! THERE IS NOBODY IS-"
The Bolton man was interrupted by an arrow sticking out of his mouth. And behind him there were hundreds of fire arrows being shot at the camp. It was terrible, the arrows looked like a rain of fire, and red slamming into the Boltons. The camp walls were caught immediately lighting on fire. The parts of the walls most likely soaked in mammoth's oil. The fire started to cause panic within the men and they all tried to run towards the three gates. Bolton men trampled themselves as they tried to leave, shot with arrows, and burned by getting to near the walls.
Finally a few Bolton men was able to trickle out of the gate, only to be met with giants, mammoths and men waiting to kill them.
That night the grounds near the long lake was named red lands. Because the grass was covered within the Red King's men's blood. Ramsay Bolton lost an arm, and his bastard brother lost an eye. Instead of the battle being known as the Raping of the Wolves it was known as the Massacre by Red Rain.
