King's Landing, South Bank of the Blackwater, White Sand Village
"Ser Barristan! Allow me to introduce him properly. This is the son of my sister, Lyanna Stark, and Rhaegar Targaryen. My sister told me his true name with her final breath: his name is Aegon Targaryen."
"This... this is impossible! Prince Rhaegar never set aside Lady Elia before he left. This child... he would be a bastard, he could not carry the name..."
In a small, weathered hut in White Sand Village, Eddard Stark presented Jon to Barristan Selmy with a solemnity that brooked no argument. The revelation hit the old knight like a physical blow; the man who had remained a pillar of stone through decades of court intrigue finally looked shaken to his core.
"The High Septon who preceded the 'Fat One' performed the secret marriage for my father and mother," Jon said, his voice calm and steady. He had grown accustomed to the weight of the lie—and the truth—behind his existence. "But to me, names are merely shadows. Whether I am Jon Snow or Aegon Targaryen, it matters little. My only goal is to save this world from what is coming."
"Save the world?" Barristan blinked, utterly bewildered.
Jon leaned forward, his eyes reflecting the dim hearth-fire as he spoke of the Long Night, the White Walkers, and the secret prophecy Aegon the Conqueror had passed down through the generations—the Song of Ice and Fire.
"You are saying... the Targaryens unified the Seven Kingdoms not for power, but to forge a shield against a nightmare?" Barristan whispered.
The information was overwhelming. Barristan had spent his life revolving around the Iron Throne—serving the madness of Aerys II and the gluttony of Robert I. He knew every scandal of the Red Keep, yet he realized now that his understanding of the world was shallow. The lords of King's Landing fought for scraps of power using filth and lies, but here was a boy with dragon-blood talking about the survival of the human race.
"So... in that 'story' of yours, I was meant to die at the hands of common assassins?" Barristan let out a dry, self-deprecating laugh. "What a poetic end for a man of my station."
"We still have time to change the ending," Jon replied. "I intend to consolidate the strength of both continents to end the threat of the Great Other once and for all. That is why I have established my base in the Stepstones."
"You are a stronger man than I, Jon," Ned Stark interrupted, his voice thick with pride and exhaustion. "I should have listened to you. I'll head back to the North to prepare our defenses. I will hold the Wall until it falls or until I do. The rest of this game... I leave to you."
Ned had finally shaken off the intoxicating illusions of the South. His journey to King's Landing had been a brutal education in the futility of Northern honor in a den of vipers. He realized now the frustration of his ancestor, Cregan Stark, who had also found the South to be a place where habit and faith made enemies of brothers.
"The Free Folk—the Wildlings—are a variable we cannot ignore," Jon cautioned. "Move them to Skagos to settle and farm if you must. Just give them grain and keep them occupied. We cannot leave them to die; every one of them who falls is just another soldier for the Night King's army."
"I've already been considering it," Ned nodded. "House Umber and the Karstarks will be difficult to convince, but as long as I am Warden, they will obey. I've learned enough of the world to know when a grudge becomes a luxury we can't afford."
Ned was recovering rapidly, his mind already turning toward the logistics of the coming Winter.
"Ser Barristan," Ned turned toward the old knight. "What are your plans now?"
"I..." Barristan looked at his hands, his brow furrowed in a fresh moment of doubt. "Is there still a place for a man like me to fight?"
He looked at Jon, then back at Ned. He wanted to return to the familiar cold of the North with a man he respected, but a deeper instinct pulled him toward the boy who had just transformed into a dragon. He wanted to see if this Targaryen could truly achieve the impossible.
"Jon is just beginning his journey," Ned suggested, sensing the knight's hesitation. "The North is safe for now, but Jon needs someone to stand by him—someone who knows the weight of a true oath."
Barristan looked at Jon with a flicker of hope, his eyes silently asking: May I?
"Ser Barristan," Jon said, stepping forward. His voice was no longer that of a nephew, but of a commander. "My men are freedmen—good people, but they lack the polish of a true military. I need a knight who can teach them that a sword is nothing without the honor to wield it. I need you."
Jon's words were sincere. He knew the history of this man—the knight who had once single-handedly rescued King Aerys from Duskendale. He didn't just want a bodyguard; he wanted a mentor and a general whose loyalty was as immovable as a mountain.
"I have no titles to give you," Jon added quietly. "No lands, no crowns, not even a ring to prove who I am. Am I worth your steel?"
Barristan's jaw set. "A true king is judged by the people he serves, not the titles he claims. Your ancestor, the Queen Who Never Was, Rhaenys Targaryen, was noble and fearless without ever wearing a crown. Her name is remembered when the names of lesser kings are forgotten."
Barristan drew his longsword. The steel rang in the quiet hut. He sank to one knee, planting the hilt in the dirt before him.
"The Father's justice shall judge me this day. The Crone has shown me the path. By the Mother's mercy, the Warrior's strength, the Smith's toil, and the Maiden's grace, I swear my life to you. If I break this vow, may the Stranger take me and my soul rot in the Seven Hells. I am Barristan Selmy of Harvest Hall. I will be the sword of Aegon Targaryen until my final breath."
Jon reached down and took the old knight by the shoulders, pulling him back to his feet.
"Thank you, Ser Barristan. Help me protect my House, as you once protected my grandfather."
Barristan's eyes dampened. To be acknowledged not as a "useless old man" to be discarded by Cersei, but as a vital pillar of a new dynasty, filled him with a fire he hadn't felt in years.
"I will, my Prince," he whispered.
"Good," Jon smiled, though his mind was already moving to the next task. "Now that we have our general, it's time to get the Starks home. We have a long voyage ahead."
