In Game of thrones with Sci fi Military system

The next day, Alex led his army into Astapor. The massive gates, adorned with the image of the Harpy, swung open with little resistance. Inside, the city was silent, its streets lined with frightened citizens and slaves unsure of their fate. The soldiers of Astapor, leaderless and demoralized, surrendered without a fight.

Alex rode at the forefront with Daenerys beside him, Ancalagon flying low above the city, his shadow casting a foreboding presence over the streets.

"Secure the pyramids," Alex commanded. "Free the slaves and disarm the soldiers. Anyone resisting will be dealt with swiftly."

His army moved with precision, soldiers spreading through the city in their respective squads, to carry out his orders. By midday, the pyramids were under Alex's control, and thousands of slaves had been freed.

The Unsullied, the famed army of Astapor, stood in perfect formation at the training yard. Their discipline was evident, but their faces betrayed no emotion.

Alex addressed them directly, his voice firm but understanding. "You are no longer slaves. You are free to choose your own path. If you wish to leave, you may do so. If you wish to fight alongside me and protect the freedom you now possess, I welcome you into my army as brothers and equals. Your previous masters have fled with their tail between their legs, now you don't have to listen to them. Make your own decisions".

The Unsullied exchanged glances, unsure at first, but slowly their resolve became clear. One stepped forward it was Grey Worm.

"I will fight for you," Grey Worm declared, his voice steady. "For freedom, and for those who cannot fight for themselves."

One by one, the rest of the Unsullied followed, pledging their loyalty to Alex.

Alex turned to Grey Worm and placed a hand on his shoulder. "You have the heart of a leader. From this day forward, you are a general in my army. You will control the Unsullied under your command".

Grey Worm bowed his head. "I will not fail you, my king."

Later that day, Daenerys toured the city, observing the changes being implemented. In one of the pyramids, she encountered a young woman with sharp eyes and an intelligent demeanor Missandei, a translator for the Good Masters.

Missandei knelt before Daenerys, her head bowed. "Your Grace, I am Missandei. I served the Good Masters, but now I am yours to command."

Daenerys lifted her chin gently. "You are no longer a slave, Missandei. You are free to live as you choose."

Missandei hesitated, then spoke with determination. "If it pleases you, I would serve you still. I wish to learn from you."

Daenerys smiled warmly. "Then rise, Missandei. You are no longer a servant, but an advisor, who should be by my side not kneeling infront of me".

Alex made the decision to remain in Astapor for a month or so, ensuring the city's stability before moving forward. He knew that abandoning the city immediately, as others had done in the past, would leave it vulnerable to chaos. Just like Dani did it in the show.

His team worked tirelessly to rebuild the economy, establish a governance structure, and integrate the freed slaves into society. The Unsullied, now part of Alex's army, maintained order and protected the city from internal unrest. Alex had summoned some governing officials from system, origin from this world so they didn't cost him much. With the help of them, he build a structural chain of command. Since they were all loyal to him, Alex was happy to leave them with matters like finance, law and order and other little things.

"Freedom without purpose is chaos," Alex told his advisors during a meeting. "We give these people not just freedom, but a future."

Daenerys looked at him with admiration.

In the days since leaving Pentos, Ancalagon had grown at an astonishing rate. Once 25 feet long, he now stretched over 33 feet and stood nearly 20 feet tall.

Alex observed him from the balcony of their temporary residence in Astapor. The dragon's wings spread wide as he perched atop a ruined pyramid, his golden eyes scanning the city below.

"He's growing too quickly," Alex remarked to Daenerys, concern in his voice.

Daenerys nodded. "It must be the blood magic from his hatching, combined with his natural growth. Dragons are powerful, but this... this is extraordinary."

Ancalagon turned his massive head toward them and let out a low rumble, a sound that vibrated through the air.

"I'll take him to Valyria someday," Alex said, his gaze fixed on the dragon. "To the place where dragons were born. But first, we must secure the Free Cities."

By the end of the week, Astapor was already showing signs of improvement. Markets reopened, people began to rebuild their lives, and the city's once-oppressive atmosphere lifted.

Alex stood on the steps of the largest pyramid, addressing the citizens. "Astapor will rise again not as a city of slaves, but as a beacon of freedom. There are no more masters who control anyone, everyone is the master of their own destiny now."

The crowd erupted in cheers, their faith in their new ruler growing stronger with each passing day.

Alex turned to Daenerys, who stood proudly at his side. "This is just the beginning," he said as he felt someone holding his hand. As he turned around, it was Daenerys, who leaned onto his shoulder. She is taking her first step to show Alex that she is opening upto him as a sign of trust and love in their relationship.

Early in the next morning, Alex sat in his chamber, his gaze fixed on Ancalagon resting outside. The dragon had become an imposing figure, his massive form nearly too large for the city streets.

"System," Alex called out, his voice steady. "Why is Ancalagon growing so quickly? This rate of growth is unprecedented."

The system responded in its usual monotone.

"Host, Ancalagon's growth is a result of multiple factors: the powerful upgraded bloodline used, his natural lineage as a descendant of the greatest dragons, and the high concentration of ambient magic in this world. However, this growth is just the beginning. Soon, he will grow at an even faster rate."

Alex raised an eyebrow. "Faster? That's... concerning. How will we sustain his food requirements when he gets that big?"

"Host need not worry. Ancalagon is already capable of sustaining himself by absorbing magic from the world around him. As he grows, he will rely more on the ambient magic in the atmosphere and less on physical sustenance."

Alex leaned back, thoughtful. "So he's essentially self-sustaining. That's a relief. But this kind of power".

Night's Watch

Far to the west, at the Wall, a grim discovery sent chills through the Night's Watch. Rangers had returned with a corpse they found beyond the Wall frozen, pale, and lifeless.

That night, as the body lay in the storeroom, it began to move. The dead man, his eyes glowing an eerie blue, attacked the guards on duty.

The chaos awoke Jon Snow and others, who rushed to the scene. The creature was relentless, impervious to swords and arrows. Finally, Jon grabbed a nearby lantern and set it ablaze.

The creature shrieked in agony as the fire consumed it, leaving behind only ash.

"Lord Commander," Jon said, his voice filled with urgency. "This is no ordinary death. The legends are true. The White Walkers are real."

The Night's Watch stood in uneasy silence, the weight of the revelation sinking in.

In the Riverlands, Tyrion Lannister rode toward Tywin's camp, flanked by the Mountain Clans who had once sought to kill him. Shagga, the leader of the Stone Crows, spoke gruffly.

"We serve you now, Halfman, but we expect payment."

Tyrion smirked. "Oh, you'll be paid handsomely. My father always honors his debts."

When they arrived, Tywin Lannister greeted them with his usual cold demeanor. He eyed the Mountain Clans with a mixture of disdain and calculation.

"You brought savages to our camp?" Tywin asked.

"They're warriors," Tyrion replied. "And they've pledged to fight for us in exchange for gold and steel. You need every sword you can get, father."

Tywin nodded slowly. "Very well. But if they cause trouble, they'll be dealt with accordingly."

The Mountain Clans grumbled but said nothing, their loyalty now tied to the Lannisters by necessity.

In King's Landing, Ned Stark's situation grew dire. After accusing Cersei of infidelity and exposing her children's true parentage, he was betrayed by Littlefinger and captured by the Lannister guards.

Imprisoned in the Red Keep's dungeons, Ned spent his days in chains, his body battered but his spirit unbroken.

Sansa, meanwhile, was a prisoner in all but name, held under Joffrey's watchful eye. Arya, having escaped the initial chaos, hid in the city's alleys, her small blade Needle her only companion.

Days later, Varys visited Ned in his cell.

"You must apologize," Varys urged. "Confess to treason, declare Joffrey the rightful king, and you may save your daughters."

Ned hesitated, his honor warring with his love for his children. In the end, he relented, willing to sacrifice his pride to protect them.

Brought before the gathered crowd in the Sept of Baelor, Ned confessed his "crimes." Sansa watched from the platform, her face pale with fear. Arya, hidden among the crowd, gripped Needle tightly.

As Ned spoke, Joffrey smirked and stood. "My mother wishes to show mercy," he declared. "But I am not so weak. Bring me his head!"

The crowd gasped as the executioner stepped forward. Sansa screamed, begging Joffrey to stop. Arya tried to push through the throng but was held back by Yoren, who recognized her and pulled her to safety.

Ned knelt, his eyes meeting Arya's one last time. The sword fell, and the crowd roared.

Sansa collapsed in tears, and Arya, hidden in the shadows, vowed revenge. Joffery didn't know that the litle stunt his just pulled off will cost him a lot in future.
