When the Wyvern riders missed their check in time, the Imperial Army was put on high alert as soldiers started doing double shifts to be prepared for when the Night King and his army walked against the Wall. Eonwe knew that this incident was more than likely related to the Night King and the army of the dead, so he requested additional support from Maximus.
A few days later, Maximus had sent 20 more Wyverns, and 40,000 more soldiers to reinforce the wall. Within these 40,000 soldiers were several young lords and Knights who sought to make a name for themselves. The title of Knight was one of the things that Maximus had kept around within Westeros. In fact, the title came with more benefits than it previously did.
Some of the Great Houses of the continent had sent their sons to serve at the Wall, compelled by both the imperial restructuring and a fear of being seen as insufficiently loyal. The new knights marched proudly under the Imperial banner, many still boys, untested and filled with anticipation while the older Dawnborn and Mamluk veterans eyed them with silent judgments.
Squires shared bunks with the veterans as form of team building between the younger and older warriors.
Jon Snow was placed in command of the Castle Black's central keep, officially "To make use of his unique knowledge of the Wildlings and the North." Unofficially, Eonwe and his commander's circle wanted to see if Jon Snow was fit for this new Order that was emerging on the Continent. In the mess, Jon felt the stares as he passed by the men of the Night's Watch and the Dawnborn. The Dawnborn were ready to see if the bastard would run or fight, to see whether he belonged to the old world or the new.
Samwell Tarly, now groomed as Eonwe's unofficial aide, became a diplomatic liasion in the afternoons, counseling the officers on how to manage the old members of the Night's Watch and the rigid cultures of all the men that were gathered here. He hated meetings, but he hated being outside more, because he could sense that something was growing beyond the wall.
This feeling gathered each day that passed. To pass the time, most days, Sam took to rubbing his hands together in front of the rune-heater while listening to the Dawnborn argue with Black Brothers over who would man the watchtowers, or who would sleep closest to the new rune-heaters. It was all friendly banter for the most part, but even that could escalate.
Even with all of Eonwe's preparations, they could not keep the fear out. One night, an outpost to the east stopped sending its midnight signal which was a warning that the enemies were upon them.
At Eastwatch-by-the-Sea, the soldiers scrambled into position, swiftly donning their armor and weapons. The Elven Commander in charge stood atop the battlements, looking into the dense fog that rolled in from beyond the Wall. "Torches," he commanded. Immediately, hundreds of torches ignited along the wall allowing some light to pierce the darkness.
For minutes nothing happened. The men held their positions, muscles tense with anxiety, eyes stinging from the cold. Veterans whispered warnings to nervous recruits, "Don't let the quiet fool you. The dead don't breathe, don't tire. They just came."
After an hour had passed, visibility remained poor. However, the Elven Commander felt a deep chill creep over him, which made it far colder than it was before. "They're coming," he whispered.
Suddenly, the ground beneath them shook. Soldiers exchanged uneasy glances as commanders shouted to keep watch. It was quiet and nobody could hear much due to how tall the wall was.
But that quiet didn't last long as from the mist, an enormous figure emerged, a Wyvern, but transformed and tamed by the Night King. Its skin now glowed with a ghostly blue hue; eyes filled with an unnatural ice-cold light. It soared toward the wall, its wingspan casting a shadow over the ground. The soldiers thought that this dragon was one of theirs, but that quickly changed once the Wyvern opened its mouth and released an icy blast.
"SHIELDS UP!" the commanders ordered, but it was too late for those directly in the path. Ice consumed them instantly, freezing dozens of men where they stood. "Archers, FIRE!" shouted a commander. "Witches, take those Wyverns down." Arrows soared upward but was shattered by the creature's icy armor. The witches tried their luck, but the Wyvern simply brushed off their attacks. Now only were these Wyverns converted by the Night King, but they were also given new abilities.
The Wyvern circled back around, unleashing another deadly breath upon the battlements. One of the men dove to the side, narrowly escaping the wave of ice that would have left him frozen.
The horns sounded, calling for reinforcements to join them on the wall and alerted the patrolling Wyverns of the attack. Almost a minute later, the Wyvern patrol consisting of 3 Wyverns had showed up to assist. 2 of the Wyverns went to fight the Night King controlled Wyvern while the last one went to the bottom of the wall. The dead had already started to climb the wall in the thousands.
The men on top of the walls had to multitask between dodging the Night King's Wyvern and focusing on the dead climbing the wall. The addition of friendly Wyverns gave them some room to breathe, but most of them were still on the watch.
At Castle Black, the dead had just arrived. Their numbers were much more immense than the ones at Eastwatch which possibly meant that this was where the Night King was attacking from.
Frozen wights massed at the base of the Wall. Rank upon rank pressed against the Wall, clawing against the ice as they began their climb. The men above had never seen such an army before, except for the men of the Dawnborn who fought against Demons.
Inside Castle Black, Eonwe grabbed his gear and took to the frontlines.
As Eonwe emerged onto the battlements of Castle Black, he joined the chaos of battle. The air was filled with shouts, cries of pain, and witches shooting magic projectiles at the dead. The other Wyvern that the Night King captured was busy fighting 3 of the Imperial Wyverns above, their roars echoing amidst the clouds.
"Hold the line!" Eonwe commanded, his voice cutting through the chaos. He drew his sword, its blade immediately igniting it with a white flame as the men around him rallied, drawing courage from his show of power.
The dead continued to climb relentlessly upwards, their pale hands clawing desperately onto the icy Wall. Archers released volley after volley, witches chanted their spells, sending blasts of fire and lightning cascading down the Wall. Yet, the undead horde continued to climb, indifferent to losses like a normal army would.
"Sir!" Jon Snow shouted from a nearby tower, pointing below. "He's here!"
Following Jon's gaze, Eonwe spotted him: the Night King, on top of the Wyvern that was fighting the other three Imperial Wyverns. The Night King calmly watched as his army scaled the Wall, while at the same time he fought off the three Wyverns and their riders.
Without hesitation, Eonwe leapt from the battlements whistling for his Griffon which came and caught him mid-air. He then ascended to where the Wyverns were fighting and started chasing after the Night King.
"Sir, he's more powerful than we thought," Shouted one of the Wyvern riders as they came up next to him.
"Don't worry, I'll deal with him, you guys just start getting rid of the dead climbing the wall." The Rider nodded as he and the other two left. Eonwe directed his Griffon upwards, closing the gap with the Night King, whose Wyvern roared at the sight of him approaching, sensing a new challenger approaching. The Night King shifted his attention to the new threat, ordering his Wyvern to start its attack.
Without hesitation, Eonwe charged his Griffon forward, straight toward the undead Wyvern. As they collided mid-air, Eonwe leapt from his Griffon and onto the Night King's Wyvern, landing on its spine. Immediately, he channeled his power into his sword which made the white flame brighter and hotter, melting the frost covered scales of the Wyvern.
The Wyvern tried to shake him off, but he was unsuccessful. So, the Night King turned around, sword in hand, covered in ice reinforced with magic. He swung at Eonwe, who parried the attack and delivered his own. Each strike from Eonwe carried an overwhelming force, steadily pushing the Night King onto the defensive. Sensing Eonwe's superior strength, the Night King summoned a wave of the freezing cold and sent it towards him.
Eonwe countered by projecting a shield, easily absorbing the attack. Taking advantage of the opening, Eonwe lunged forward, landing a powerful strike against the Night King's armor, staggering him. With the Night King visibly staggered, Eonwe pressed his advantage, delivering a relentless barrage of attacks. Each strike was precise and overwhelming, breaking down the Night King's defenses. The undead Wyvern below them had begun to falter as Eonwe's aura intensified causing the creature's strength to disappear.
The Night King, sensing defeat, attempted one last desperate attack, swinging his blade in a wide arc. Anticipating this, Eonwe swiftly stepped aside, before countering with a devastating blow. His flaming sword piercing through the Night King's chest.
For a brief moment, silence hung in the air as the Night King looked down in disbelief. Then, his body fragmented into shards of ice, scattering into the wind. The undead Wyvern beneath them dissolved into mist, its remnants carried away by the cold wind.
Immediately, the wights climbing the Wall below ceased their movements, collapsing lifelessly to the ground. Victorious shouts erupted from the soldiers along the Wall.
Eonwe landed atop Castle Black amid the roaring cheers. Soldiers and commanders gathered around him, awe evident in their eyes. Eonwe raised his sword, "The Night King is defeated. Tonight, we have triumphed against darkness. But remain vigilant, for our task to protect this land never truly ends." The men around him cheered louder, knowing they stood victorious, inspired by Eonwe's power.
It was rather quick victory for the Imperial forces as the Night King was facing an organized army that had not just magic in their hands but also had Eonwe who was a very powerful person compared to the Night King.
Thought the beer wasn't immediately rolled out. Eonwe wanted a report from all the other fortresses and to make sure that all of the dead were actually dead.
Outside of the Wall, on the ground, a Wyvern landed on the ground as the rider jumped off of its back. In front of them stood one of the Others, possibly the last one out of the handful that actually existed. Most of them met their end in various locations across the wall, leading parts of the Night King's army. Usually some of them would stick with the Night King, but since he was riding his Wyvern, they were sent elsewhere.
Now the last remaining Other stood standing in front of a Wyvern and its rider. The rider had no intention of wasting time fighting against this undead, so he moved to the side and watched as the last enemy was burned to a crisp. The rider had walked to where the enemy was burned and checked to see if that was a normal enemy or one of the rumored powerful ones.
A few hours later, after it was relatively confirmed that the Night King and his army were defeated, the alcohol was rolled out and the army celebrated. Over the course of the next several days, the word had spread about the undead Army that attacked the Wall and the brave soldiers who defended the wall with little casualties.
