The Lord of the Rings: Lords of Middle-earth.

"This is the northern border of the Empire! I am the Grand Duke of the North! I am here by imperial decree to rule the North! There are over ten thousand soldiers here ready to fight! My Knights of the Empire still hold their prestige! What do these scum have to do with the internal strife of the Empire? How dare they invade from all sides! Do they think I am one of those incompetent nobles?" The enraged Grand Duke stood on the Northern Wall, leaning on his sword, and cursed loudly.

The greatest sorrow is the death of the heart. The Lord of the North, the King's Landing family, has died out (although there are still direct descendants). The last Grand Duke of King's Landing of the Empire collapsed instantly. Everything he held onto had lost its meaning. So let him die for his country with his clan!
When nearly a thousand King's Landing knights gathered from all directions at their lord's command, the last Grand Duke of King's Landing seemed to rediscover the same drive he had when he first donned the Grand Duke's crown. These were private soldiers loyal to their family, the last organized thousand-man knightly order of the empire, and the last hope for the empire's revival. Unfortunately, they would be led to destruction under their lord's leadership. They would break out of the fortress, cross the Wall, and launch a desperate charge against the northern orcish coalition.

"In this battle, the Empire's banners will fall forever, but I will make those scum remember these two banners for thousands of years! I will make them live in fear for an entire era!" The Grand Duke pointed at the Lagrange Dragon Banner and the Lion Banner of King's Landing with a maniacal laugh, but his laugh was filled with bloodshed, and the North was destined to be awash in blood...

The response to the frenzied Duke of King's Landing was the silence of the King's Landing knights. There were no passionate shouts, no desperate cries; each knight calmly gazed at his lord, adjusting and restoring their composure so they could face the enemy in their best condition.

"Child, let's rush out and close the city gates, lock him up! Let's defend King's Landing to the death!" The Grand Duke of King's Landing weakly shook his arm and said to the young knight.

"Your Highness..." The knight reluctantly reached out his hand.

"It's over, it's all over. If I'm not mistaken, the Wall of the North should have been breached by now. Those barbarians and orcs attacked from both sides... The fortresses guarding both ends of the Wall of the North should have fallen by now..." The Duke of King's Landing gazed sadly into the distance. He had already foreseen this outcome when he summoned all the knights. Without the assistance of the Knights of King's Landing, the ordinary swift infantry and valiant warriors of the Northern Garrison Legion were certainly not enough to withstand those fierce and ruthless troops.

"Intrigue, betrayal, ha! What did those traitors gain? A throne? A royal throne? Wealth? Land? Or just a vague chance to become a god?" The Duke of Junlin laughed mockingly.

"The Sword and Shield family..." The young knight pursed his lips and didn't continue. The ambitious Sword and Shield family wanted to further enhance their status in the empire, but they never expected that natural disasters and man-made calamities would come together, and an internal war among the nobles would eventually lead to the collapse of a vast empire.

"The Sword and Shield family? Hahaha! Although they are ambitious, I still have to think highly of them! Even though they are the ones who caused everything that is happening now!" The Grand Duke of Junlin grinned. The ambitious Sword and Shield family, like most nobles in the empire, wanted to enter another class after generations of accumulation. However, the intrigue and backstabbing among nobles made their rise hopeless and they were suppressed. The Sword and Shield family was still a powerful marquis family on the border. In a moment of anger, they raised an army and had a glorious duel between nobles. It was originally just a matter between nobles, but they were taken advantage of and attacked from all sides. The empire, surrounded by enemies, was quickly dismantled by enemies coming from all directions.

The Sword and Shield family did not disgrace the military nobility of the Lagrange Empire. The entire family fought to the death in front of Lagrange City until the last family soldier fell. Therefore, the Grand Duke of King's Landing still recognized their responsibility as nobles.

"Let's go, let's get ready," the Duke of Junlin said softly, waving his hand.

"There's no need to feel sad for me and this empire. There are no civilians left here. As soldiers of the empire, this is the only place we can do our final act of loyalty to the empire!" As if seeing the sadness in the young knight's eyes, the Grand Duke smiled and patted his head. In him, the Grand Duke saw the shadow of his father.

"Let us be buried with this great capital, King's Landing, standing atop the Wall in the North!" The Grand Duke downed the hot wine in his flask and tossed the silver vessel to the ground. "Imperial knights! King's Landing vassals! Northern children! Let them see how warriors from the wilderness fight! Charge with me!" The Grand Duke drew his longsword and swung down the dozens-of-meters-high wall, landing safely with a slight bend in his knees. A terrifying surge of battle aura rose more than ten meters high, revealing the Grand Duke to be a sixth-tier hero!
"Creak~" The heavy alloy gate, which was twenty meters high, was opened from the inside. The Grand Duke's side horse charged out first, and fiery red battle aura flames bloomed. Behind him were one after another of the King's Knights, who also activated their fiery red battle aura flames. The entire knightly order pressed rapidly toward the north like a flame totem spread across the earth.

Unlike many other knightly orders that have knights of various attributes, the Royal Lion Knights, like the Royal Holy Knights, are composed of knights of a single attribute. Although they lack attribute diversity and are easily suppressed by the attributes that counter them, the strong synergy of the same attribute is, to some extent, invincible!
"Glory!" Every member of the King's Knights donned a layer of battle armor.

……

With each knightly verse uttered, another layer of their aura was added. When they reached the eighth layer, the aura of each knight was so heavy it was suffocating. This was the last thousand-man knightly order of the empire, the empire's swan song, the pinnacle of the northern human race, they were Kings! Behind them was that roaming lion! That fiery lion that had suppressed the north for countless years!

"Sacrifice!" they roared, enveloped in blinding golden and green light—the power of life, each glimmer a burning flame of life. They had chosen death; this was an army from hell…

……

"Lock down the fortress!" The young knight stood atop the city wall, gazing at the distant scene of war and smoke. The sacrificial Knights of King's Landing, like demonic fire, seemed intent on burning away all impurity in the world, leaving scorched earth in their wake... After watching the doomed knightly order ignite the orc army, the young knight shed a single tear, a tear that instantly turned into an ice bead as it slid down his cheek...

……

"Grand Duke Delanur Breo is dead, the King's House is extinct!" As the battle cries grew closer, the knight scribbled this short letter, tied it to a carrier pigeon's leg, and released it. He then glanced longingly at the house where his lord had once lived, before smashing the oil lamp! In the flames, he donned a heavy helmet, drew his longsword, and stepped outside…

Along with this family, a vast empire also perished!

The King's Landing family is one of the important noble families in this book. They are loyal and humble, brave and righteous, and are the last piece of land in the empire that still raises the imperial dragon flag.
