Winter settled into Casterly Rock more gently after the Lannister hypocausts.
Not softly. Never softly. The Rock remained itself—great, ancient, half fortress and half lion-shaped challenge to weather and reason both. Sea wind still struck the cliffs with relentless force. Damp still clung to lower stone where old bones of the castle met the breath of the western water. The sky still turned iron-gray some mornings and made lesser households feel as though the gods themselves had decided to sulk.
But now, in the chambers that mattered most, the cold no longer won by default.
That changed Tyrion first.
Not into health. Nothing so miraculous or false. He remained what he had always been in this life: a brilliant mind housed in a body the gods had assembled with too little generosity and too much fragility. He still tired too quickly. Still coughed in damp weather. Still needed care with drafts, exertion, and the kind of small seasonal illnesses other children survived with only a day of boredom. But winter no longer reached him as easily. The rooms themselves held warmth. The floors no longer stole it from his feet. The air around his writing tables and reading chairs did not turn him stiff and pale merely because the sun had gone.
That mattered.
It mattered enough that by the middle of the season he could sit through longer account sessions without fading. He could read in the smaller library after dusk without being wrapped in so many layers that moving his arms looked like an act of war. He could work with Mordred over ship ledgers, route schedules, and grain tallies for almost two full hours before exhaustion dragged at him hard enough to be noticed.
Tywin noticed, of course.
He noticed everything to do with Tyrion.
The first time he came into the smaller account room and found his youngest son still working after twilight with color in his face and no obvious battle being fought between his body and the room, he stopped in the doorway and simply looked.
Mordred sat across from Tyrion with two port books open and a half-finished line of corrections marked in red ink. Tyrion had a stylus in one hand, a blanket over his legs, and all the grave focus of a seven-year-old born offended by sloppy arithmetic.
The warmth in the room lay quiet and constant around them. No choking braziers. No frantic servants feeding fires every half hour. Just stone holding heat and a single lamp burning cleanly at the table's center.
Tywin said, "How long?"
Mordred did not look up. "An hour and forty minutes."
Tyrion, already learning that his father asked that question not from idle curiosity but from concern sharpened into numbers, answered before being prompted further. "I rested first."
Tywin's gaze moved to him. "And now?"
Tyrion lifted one shoulder. "A little tired."
That alone would once have been enough to end the work.
Now Tywin crossed the room, put one hand briefly against the warmed stone of the wall beside the writing table, and looked down at the account sheets instead.
"What did you find?" he asked.
Tyrion brightened at once.
Mordred hid a smile and let him explain.
An overcount on wool export weight from Lannisport. An under-marked fuel expense in the southern route cost projections. A discrepancy in salt storage that likely came from one steward copying a previous year's assumptions into the present tally without checking the weather-related spoilage.
Tywin listened to every word.
Not indulgently. Respectfully.
When Tyrion finished, Tywin said, "Good."
There it was again: that Lannister word that carried whole landscapes of feeling when spoken by the right mouths.
Then Tywin looked back to Mordred. "The other western rooms begin next month."
It was not a question.
Mordred leaned back in her chair. "I thought so."
He looked once more at Tyrion, who had already bent back over the page with renewed determination because being taken seriously by Tywin was its own kind of dangerous fuel.
"Another half hour," Tywin said. "Then bed."
Tyrion opened his mouth.
Tywin lifted one brow.
Tyrion shut it again and nodded.
After Tywin left, Mordred looked across the table at her little brother and said, "You know he loves you like a military campaign."
Tyrion sneezed into the crook of his arm and muttered, "That remains very inconvenient."
Mordred laughed softly. "Yes."
Mors and Joffrey had discovered wrestling.
Not wrestling as some proper noble tutor might have wished to introduce it, with measured holds and careful balance and all the educational language men used when trying to make violence sound civilized. No. The boys had discovered wrestling the way storms discovered roofs.
By impact.
At five, both were already larger than any nursery maid in the kingdom would have chosen for peace of mind. Joffrey had Robert's broad chest beginning under childhood softness and a center of gravity that promised future battlefield confidence. Mors had Mordred's impossible solidity in a body built from the start to become more. He was not yet towering, of course, not at five, but he was dense. Hard. The sort of child who ran into things and expected them to apologize.
The first true disaster took place in the inner training yard.
The boys were meant to be practicing shield positions under Ser Harlan's eye while Mors wore his little studded practice shield and Joffrey a weighted wooden hammer still too large for any ordinary child but already managed with ugly little competence by him.
Tyland was nearby, chasing a thrown strip of red cloth with the predatory delight of a three-year-old who moved too quickly for comfort. Tyrion watched from the heated gallery above in a padded chair near the open arch, wrapped in wool and still severe enough to look like a tiny old scholar judging military decline.
Jaime had come west from the capital and stood with Mordred by the rail. Robert and Cersei, visiting with Joffrey because kingship did not entirely prevent Robert from wanting to show off his son at every opportunity, watched from the lower shade awning. Joanna sat between them all with a cup in hand and the expression of a woman who knew something was about to break and only hoped it would not be a child.
Joffrey swung.
Mors blocked.
Joffrey altered the line mid-motion and drove the wood lower into Mors's side instead of his shoulder.
Mors did not retreat.
Instead he lowered his head like a tiny furious bull and hit Joffrey square in the chest with the shield.
They both went down.
Then, because five-year-old boys with too much blood and too little moderation should never be underestimated, they did not separate.
They grappled.
No style. No grace. Just broad little limbs, fury, instinct, and a level of physical confidence no one present found remotely comforting.
Joffrey got one arm around Mors's neck and tried to roll him.
Mors simply planted himself and heaved.
Joffrey, too smart to insist on a lost position, shifted and tried to take the side.
Mors bit his shoulder.
Cersei stood up so fast her chair nearly went over.
Robert laughed so hard he had to clutch the pillar beside him.
"Seven hells," Jaime said under his breath.
Tyland, from the ground level where he had stopped chasing cloth to watch with total fascination, shouted, "Do it again!"
Tyrion, from above, sighed deeply. "Neither knows what rules are."
"No," Mordred said with all the savage pride of a mother witnessing absolute chaos. "That's why they're interesting."
By the time Ser Harlan and Jaime separated them, both boys were red-faced, dust-covered, and furious at the injustice of adult interruption.
Joffrey pointed at Mors. "He bites."
Mors pointed back. "He cheats."
Robert laughed harder.
Cersei rubbed at her brow as though warding off a headache centuries in advance. "Gods preserve me."
Joanna looked over the yard and said, with remarkable calm, "No. I think the gods have been quite clear that this is punishment."
Tyland clapped.
Tyrion made a note on his wax tablet.
Later, when Mordred asked what he had written, he said, "Joffrey changes plans in motion. Mors ignores pain if angry enough. Both are going to be exhausting."
That was perhaps the most accurate military assessment anyone had yet made of them.
Tyland grew sharper by the week.
At three, his speed had gone from amusing to troubling in all the best ways. He moved through rooms like a dart of intent. Not magical. Not impossible. Just fast enough, light enough, and blessed with such natural balance that adults misjudged his position constantly. He was forever a half-step farther than they thought, already around the corner they had only just looked at, already at the other side of a chair, already tapping someone behind the knee and skipping away before they fully turned.
Where Mors met the world head-on, Tyland flowed around it.
He loved cloth. Loved movement. Loved the feel of a light training blade in his hand even if he was still years too young to be taught any serious discipline. He had no patience for weight. No love for shields. No interest in "standing properly" when he could instead slip, dart, turn, and strike from the side.
One afternoon Mordred found him in the smaller western corridor facing a household guardsman twice his height and a hundred years his elder in practical experience. The man was on one knee because Tyland had declared that was "more honest" than forcing him to stoop. The child held a carved practice sword barely longer than his forearm and was conducting what he considered a duel.
"You're dead," Tyland informed him.
The guard, who had somehow been maneuvered into standing between two pillars while Tyland danced just outside reach, sighed. "My prince, I am not dead."
Tyland smiled. "You are if I'm mean."
"That seems unfair."
"Yes."
Mordred leaned against the arch and watched in silence.
Tyland shifted left, then right, then cut in so fast the guard actually flinched before remembering the weapon was wood. The strike itself would not have killed anyone. The timing of it, however—just as the older man turned his head to answer—was excellent.
Tyland saw Mordred then and brightened at once.
"Mother! He's slow."
The guard looked at her with the expression of a man praying for mercy from whichever authority might have the sense to end this.
Mordred considered the scene. "He is."
Tyland beamed.
The guard looked betrayed.
Then Oberyn appeared at the far end of the corridor, took in the tableau in one sweeping glance, and started laughing before he had even fully reached them.
"Mordred," he said, still smiling, "you are raising a problem."
"No," she said. "We raised two. The first one hits harder."
Tyland heard only enough of this to conclude he was being discussed interestingly and therefore should perform. He spun, switched his grip, and made a second mock cut from a completely different angle.
The guard yelped.
Tyland crowed with triumph.
Oberyn came closer and crouched to his son's level. "Show me."
Tyland turned at once and demonstrated the movement again, this time with all the exaggerated precision of a child trying to impress a parent and succeeding because the raw shape underneath the theatrics was real.
Fast. Narrow. Redirected in the middle. No force. All timing.
Oberyn looked at Mordred over the child's head and said quietly, "There it is."
Yes. There it was.
Not swordsmanship yet. But the birth of it.
Tyland's whole body already wanted to turn fights into movement and openings rather than collisions. He would grow into that blade-work beautifully and terribly.
Mordred folded her arms. "He's going to ruin someone's day."
Oberyn glanced back down at their son, who was now trying to convince the kneeling guardsman that dying politely was more dignified than losing slowly. "A beautiful day to ruin someone's day," he said.
Mordred barked a laugh.
Tyland, having no idea what was funny but enough instinct to know he had been praised, grinned with all his little fox-faced elegance and then promptly vanished around the next corner before either parent could stop him.
The guard sighed. "He does that."
"Yes," Mordred said. "Often."
Tyrion's relationship with the children changed as they grew.
He had once studied them like phenomena. Now he increasingly treated them as inevitable disasters requiring management.
Mors loved him in the straightforward way he loved people he considered his. He would barrel into Tyrion's rooms at full speed if not checked, then stop short with exaggerated care because by then even he understood that Tyrion was not built for impact. Joffrey respected him more than most adults because Tyrion never spoke to him like a baby prince and because Tyrion's observations, when offered, made frighteningly practical sense even to a five-year-old already built to like useful things. Tyland adored him the way all small fast predators adored the one person in the room who always seemed to know where they had been and what they intended before they did it.
One winter evening Tyrion sat in his heated solar with all three boys around him.
Mors lay on the warmed floor under the table, carving savage little lions into a bit of soft wood with his tongue caught between his teeth in concentration. Joffrey sat on a stool beside Tyrion's chair, holding a child's hammer in his lap and asking grave questions about whether one could break a man's ribs without killing him if one "hit only one side." Tyland was perched on the windowsill in a patch of fading light, spinning a training dagger by the handle despite repeated instruction not to.
Tyrion pinched the bridge of his nose.
"No," he told Joffrey. "That depends entirely on the man."
Joffrey frowned. "So I'd have to know the man first."
"Yes."
Mors, without looking up from the carving, said, "Just hit harder."
"That is not analysis," Tyrion said.
"It works."
"Not always."
Tyland, still twirling the dagger, smiled toward the fading sky. "It does if you are very quick."
Tyrion looked at the three of them and thought, not for the first time, that the realm was doomed in the most interesting possible way.
Then the windows rattled.
Only slightly. Only from a gust. But the temperature beyond the glass shifted enough that Tyrion noticed at once. He coughed once into his sleeve, sharp and involuntary.
All three children looked at him.
It happened so quickly it would have been invisible to anyone who did not know them well.
Mors sat up at once.Joffrey's hand tightened on the hammer and his whole face sharpened.Tyland stopped spinning the dagger entirely.
"You're tired," Joffrey said.
Mors crawled out from under the table. "And cold."
Tyland slid off the sill. "I'll shut the inner curtain."
Tyrion blinked.
Then, because he was seven and too proud and deeply loved in ways he still found difficult, said, "I am neither."
The boys ignored him.
Mors dragged the extra wool from the chair. Joffrey moved the footstool without dropping the hammer. Tyland darted to the curtain and pulled it closed with a speed that made the old rings squeal in protest.
Tyrion stared at all of them.
When Joanna entered a moment later with Mordred behind her, she stopped in the doorway and simply looked.
The room had rearranged itself around Tyrion.
Not out of pity. Instinct.
Mordred's face changed by only a degree. Enough.
Joanna smiled with that dangerous maternal softness that meant she had just seen something she would carry in her heart for years.
"What happened?" she asked.
Mors said at once, "He coughed."
Joffrey added, "The window let wind in."
Tyland, still holding the curtain edge, said, "So we fixed it."
Tyrion sank lower into the chair with the exact expression of a child who wanted simultaneously to vanish and to preserve the moment forever.
Joanna crossed the room and touched his hair. "Good," she said to all of them.
The boys straightened.
Mordred, looking between her son, her nephew, her youngest brother, and her second son, said quietly, "Very good."
Yes, she thought. Let them be dangerous. Let them hit hard, move fast, think cruelly where needed. But let them also know which lives are theirs to guard.
That mattered.
Perhaps more than anything else.
By the end of the chapter, everyone knew.
Not about Elenei. Not yet. But about the fact that another child was coming.
The signs had sharpened enough that concealment no longer made sense, and the household had already learned from Mors that waiting too long merely allowed Tyrion to deduce things with intolerable accuracy.
So Mordred told them at supper.
Not the whole hall. Only family.
Tywin at the head of the table. Joanna at his right. Jaime briefly west again from court. Cersei and Joffrey still at the Rock for the season. Robert absent—off hunting, or drinking, or hunting while drinking, which in his reign often amounted to the same thing. Tyrion in his heated chair with a blanket over his knees and a cup of broth he pretended not to like. Mors and Joffrey at the lower side-table wrestling over carved warhorses. Tyland humming quietly to himself while sawing through roast apple with inappropriate focus for a child his age.
Mordred set down her cup.
"I'm pregnant."
The table went still.
Mors looked up first. "Baby?"
"Yes."
Joffrey immediately said, "Another boy."
Mors frowned. "Maybe."
Tyland blinked once and smiled. "Good."
Cersei laughed under her breath. "There goes peace."
Jaime leaned back in his chair with helpless delight. "Gods help us."
Tywin said, "Good."
Of course he did.
Joanna smiled and reached for Mordred's hand beneath the table where no one else would see.
Tyrion looked at her for one long evaluating moment.
Then: "You've been eating around smells for twelve days."
The whole room turned.
Mordred stared. "You counted?"
Tyrion sneezed and looked offended by the suggestion that he would not.
Jaime lost the fight against laughter first. Then Cersei. Then even Joanna, though she tried for dignity and failed.
Tywin's mouth moved by almost nothing, which in him at supper counted as near hilarity.
Mors banged his little horse against the table. "Baby!"
"Yes," Mordred said, smiling despite herself. "Baby."
Joffrey narrowed his eyes in thought. "Girl."
This time the room shifted in a different way.
Mordred looked at him.
"Why?" Joanna asked gently.
Joffrey shrugged in the broad careless little-Baratheon way that somehow already belonged to him completely. "Because Mors is a boy. Tyland is a boy. So this one should be different."
Tyland considered that and nodded solemnly. "That seems fair."
Mors squinted as if trying to imagine a category of person distinct from himself and Tyland.
Tyrion said quietly, almost to himself, "Elenei."
No one had told him the name.
No one.
Mordred felt her skin go cold and warm at once.
Joanna's fingers tightened lightly around hers under the table.
Tywin looked at Tyrion with one of those unreadable expressions that meant he had just accepted fresh proof the child was terrifying in ways no one would ever fully get ahead of.
Cersei breathed out a laugh. "Of course he knows."
Tyrion, hearing himself discussed and disliking the implication that this was surprising, looked deeply annoyed.
Mordred smiled slowly.
Perhaps.
Perhaps Elenei was already on her way.
And perhaps, in a house full of force and speed and stone and heat and children who broke things simply by becoming themselves, the next danger coming into the world would not hit hardest with shield or hammer or blade—
but with poison and silk and a mother's mind turned sharp in a daughter's hands.
Good.
The realm, she thought, would deserve her too.
