The next morning, Alexander arrived at the library to find that Samwell was already there, surrounded by books and looking considerably more animated than he had the previous day. He was not alone. Seated across from him, her chin propped on her hand and a look of attentive curiosity on her face, was Margaery Tyrell.
"Lord Alexander," she said, with a smile that suggested she had been waiting for him. "Sam has been telling me about your astronomical discoveries. I confess I understood perhaps one word in three, but the one I understood most clearly was 'extraordinary,' which Sam has used approximately eleven times in the past quarter hour."
"It was perhaps nine times," Samwell protested, though his flush suggested the count might have been accurate.
Alexander settled into the chair beside them, noting with quiet satisfaction the dynamics of the scene. Samwell was relaxed in a way he had not been the previous day, his natural shyness softened by Margaery's warmth and the lingering confidence that came from having his work validated. Margaery, for her part, seemed genuinely interested in what Samwell had been explaining, though Alexander suspected her interest was as much in the person as in the subject matter. She had a talent for making people feel valued, and she deployed it with the precision of someone who understood that kindness, like cruelty, was a tool that could be sharpened.
"I was explaining the elliptical model," Samwell said, turning back to his notes with the eagerness of someone who had found a willing audience after years of solitude. "The idea that stellar orbits are not circular but elongated, which accounts for the irregularities in seasonal timing-"
"Perhaps start with the practical implications," Alexander suggested gently. "Margaery has many talents, but I suspect abstract mathematics is not the one she would choose to exercise before breakfast."
"It is not," Margaery confirmed, with a laugh that was warm and unaffected. "But I do enjoy understanding how things work. I simply prefer the explanation to begin with 'this is why it matters' rather than 'consider the following equation.'"
"Then consider this," Alexander said. "If Sam's theory is correct, and I believe it is, then the long seasons that define life in Westeros are not random. They follow a pattern, a predictable cycle that can be calculated in advance. Which means that we could, in principle, know when the next long winter is coming. Not guess. Know. With enough precision to plan for it, to store food, to prepare defences, to save lives."
Margaery's expression changed. The playful curiosity was still there, but beneath it, something sharper had surfaced, the intelligence that she usually kept partially concealed behind her warmth.
"If you could predict winter," she said slowly, "then whoever controlled that knowledge would have an extraordinary advantage. Every lord in the realm would want it. The Citadel would want it. The Crown would want it."
"Yes," Alexander said. "Which is why we are going to develop the theory carefully, verify it thoroughly, and share it selectively. Knowledge is like any other resource. Its value depends on how it is distributed."
"You sound as though you are planning a campaign, not writing a scholarly paper."
"In this world, Lady Margaery, the two are often the same thing."
They spent the rest of the morning together, the three of them, and the dynamic that developed was natural and surprising in equal measure. Samwell provided the scholarly depth, Alexander the strategic framework, and Margaery the social intelligence that connected abstract ideas to practical realities. When Samwell became lost in theoretical tangents, Margaery asked the questions that brought him back to earth. When Alexander grew too focused on applications and outcomes, Samwell reminded him that the theory needed to be sound before it could be useful. And when both boys became too serious, too absorbed in the weight of what they were discussing, Margaery offered observations that were witty and disarming and that reminded them both that they were fourteen and fifteen years old, sitting in a sunlit library, and that not everything needed to be a matter of life and death.
"You two are going to change the world," she said, as the morning wore on and the conversation shifted from astronomy to history to the particular challenges of growing up in families where expectations were a heavier burden than most people could imagine. "I am not sure the world is ready."
"The world is never ready for change," Alexander replied. "That is rather the point."
"And what is my role in this world-changing enterprise? Am I simply to sit and admire?"
"You are to do what you do best, which is understand people. Sam and I can build theories and systems, but theories and systems do not persuade. People persuade. And understanding what people want, what they fear, what motivates them to act or to hesitate, that is a skill as valuable as any mathematical insight."
"He is saying that you are a politician," Samwell offered, with a shy grin that suggested he was growing comfortable enough to attempt humour.
"I prefer 'diplomat,'" Margaery said. "It sounds less like an insult."
"In my experience," Alexander said, "the only difference between a politician and a diplomat is that a diplomat has better manners. The underlying skill set is identical."
Margaery threw a dried apricot at him. He caught it without looking, an instinct honed by years of training that occasionally manifested in ways that made people stare, and ate it.
"Show-off," she said.
"Practical," he corrected. "Why waste food?"

The days that followed were among the most pleasant Alexander could remember.
He had spent so much of his life in deliberate preparation, planning and building and calculating with the relentless discipline of someone who knew that failure was not merely possible but inevitable without constant effort, that he had almost forgotten what it felt like to simply enjoy himself. Not the strategic enjoyment of a successful negotiation, or the intellectual satisfaction of a problem solved, but the uncomplicated pleasure of spending time with people he genuinely liked, doing things that interested him, without any agenda beyond the moment itself.
The three of them explored Highgarden together, and the castle revealed itself in layers, each more impressive than the last. The gardens alone could have occupied weeks of study, a vast, interconnected system of cultivated beauty that ranged from formal arrangements of geometric precision to wild, deliberately untamed spaces where nature had been allowed to express itself without restraint. There were hedge mazes and rose gardens and orchards heavy with fruit, and hidden paths that wound through groves of ancient trees whose canopies filtered the sunlight into patterns of green and gold that shifted with the breeze.
Samwell knew the library's contents with an intimacy that bordered on the encyclopaedic, and he led them through its treasures with the enthusiasm of a man who had finally found companions worthy of sharing his passion. They discovered manuscripts together, argued over historical interpretations, and spent one memorable afternoon attempting to decode a cipher in a pre-Conquest Hightower journal that turned out to be nothing more exotic than a recipe for fish stew rendered in elaborate secrecy by a lord who was embarrassed by his fondness for common cooking.
"All that effort," Margaery said, laughing until she had to lean against a bookshelf for support, "for fish stew."
"The effort is what makes it remarkable," Alexander replied. "Anyone can hide a battle plan or a political secret. It takes a certain kind of commitment to apply state-level encryption to a recipe for haddock."
"My father would understand," Samwell said quietly. "He guards the recipe for Horn Hill's venison pie as though it were the key to the Iron Throne."
The mention of Randyll Tarly cast a brief shadow across the conversation, as references to Samwell's father always did. Alexander noted it, filed it away, and redirected.
"Speaking of secrets," he said, "I have been thinking about communication. Specifically, about the problem of sending messages that cannot be intercepted and read by people for whom they were not intended."
Samwell's eyes brightened. Margaery's expression sharpened with interest.
"Ravens can be intercepted," Alexander continued. "Letters can be opened, copied, and resealed. Even coded messages can be broken if the code is simple enough and the person reading it is clever enough. What we need is a system that is both secure and practical, something that only we can read, but that does not require hours of effort to encode and decode."
"A cipher," Samwell said immediately. "But you just said that ciphers can be broken."
"Simple ciphers can be broken. A substitution cipher, where each letter is replaced by another, can be cracked by anyone who understands the frequency of letters in common speech. But there are more sophisticated approaches. What if the key to the cipher changed with every message? What if the method of encoding was itself encoded, so that even someone who intercepted a message and had unlimited time to work on it could not decipher it without knowing not just the key, but the system that generated the key?"
"A key that changes," Samwell repeated, his expression shifting from interest to focused concentration. "You mean like a book cipher, where the key is a specific page and line in a text that both parties possess?"
"Similar, but more flexible. I am thinking of a system based on a shared vocabulary of symbols, each with multiple possible meanings depending on context. Not a direct letter-for-letter substitution, but a conceptual language, where the symbols represent ideas rather than individual characters. The meaning of each symbol would depend on its position in the message, the symbols around it, and a rotating key that determines which of its possible meanings is active at any given time."
Margaery watched the two of them, her expression that of someone observing a game whose rules she was learning in real time. "And who would know this system?"
"Us. The three of us, and no one else. Not our families, not our maesters, not our servants. A private language, known only to the people who created it, changed and updated through channels that only we control."
"Why?" Margaery asked. The question was simple, but the intelligence behind it was anything but. She was not asking about the mechanics. She was asking about the purpose.
Alexander met her eyes, and in that moment, he made a decision about how much to reveal. Not everything. Not yet. But enough to be honest, which was, as he had told her at the feast, the foundation of any relationship worth having.
"Because the world is going to change," he said. "I do not know exactly when, or exactly how, but I know that the stability we currently enjoy will not last. When it breaks, the people who survive will be the ones who can communicate quickly, securely, and reliably. I want us to be those people."
The silence that followed was heavy with implications that none of them fully articulated.
"You are serious," Margaery said. It was not a question.
"I am always serious. It is one of my less endearing qualities."
"No," she said. "It is one of your most endearing qualities. Possibly the most." She looked at Samwell, who had been listening with the expression of someone who was beginning to understand that this friendship was going to be considerably more significant than he had initially imagined. "I think we should do it."
"So do I," Samwell said. "Though I reserve the right to suggest improvements to the mathematical framework."
"I would expect nothing less," Alexander said. And he meant it.
They spent the next two afternoons designing the foundations of their code, a system that they called, with the kind of dry humour that was becoming characteristic of their group, the Quiet Language. It was built on principles that Alexander provided, tested through problems that Samwell devised, and refined through practical objections that Margaery raised whenever the system became too complex for rapid use. By the time they had finished the initial framework, they had created something that was, by any reasonable standard, unbreakable by anyone who did not possess the shared knowledge that underpinned it.
And they had created something else, something less tangible but equally valuable: a bond. Not the kind of bond that came from shared blood or political alliance or the obligations of feudal loyalty. A bond of choice, freely given and mutually understood, between three young people who had recognised in each other something worth protecting.
Alexander found himself thinking about it as he lay in his chambers that evening, staring at the ceiling and listening to the night sounds of Highgarden drifting through his open window. He had planned for many things. He had built strategies and contingencies and fallback positions for scenarios that ranged from the probable to the nearly impossible. But he had not planned for this, for the simple, powerful experience of making friends who mattered not because of what they could do for him, but because of who they were.
It was, he reflected, both the most pleasant surprise of his time in the Reach and the most dangerous. Because caring about people made you vulnerable. It gave the world leverage against you, handles that could be gripped and twisted by anyone who understood how to use them. Every person you loved was a potential hostage, a point of pressure, a weakness disguised as strength.
And yet.
What was the point of building anything, of all the planning and preparation and relentless effort, if there was no one to share it with? What was the point of safety if there was no one worth keeping safe?
His mother had understood that. She had come to Tarth from across the sea, leaving behind everything she knew, because she had chosen love over security. She had died young, but she had died in a place she had chosen to be, surrounded by people she had chosen to care about, and Alexander thought that there were worse ways to measure a life.
He would protect Sam and Margaery. Not because they were useful, though they were. Not because they were strategically valuable, though they were that too. But because they were his friends, and protecting the people you cared about was the only thing that made the game worth playing.
He closed his eyes and slept without dreams.
