History repeats itself; House Lannister
"Your royal highnesses! Prince Lyonel! Princess Argella! Princess Elinor!"
The twenty-year-old Galladon Tarth, heir to Evenstar Hall on the island that had given his family their name, tried to find the royal children. He had last seen them through a window with their septa Holly and Sandor Clegane, right before the rain of burning hail had started.
"Prince Aemon! Princess Myrcella! Prince Tommen!"
Right behind the young knight was an out-of-breath Samwell Tarly, trying to help the fellow noble heir by at least being useful to search for the royal heirs while the King and his brother had ridden out to face the strange winged beasts and their riders.
"Ser Galladon!"
It was Myranda Royne, his betrothed from the Vale and one of many young noble daughters here at court, who looked rather shaken from seeing how even the whole Red Keep had taken noticeable damage from the hail. She did not seem injured, thankfully.
"T-the whole Sept of Baelor...it has collapsed!"
The tall towers of the Great Sept had indeed been broken from the hail, and the lower buildings alongside the dome were on fire thanks to the holy oils for ceremonies which had been stored by the Faith there.
"Myranda, please take yourself to the lower parts of the Red Keep, I must find Brienne and the royal children…!"
Her usual playful nature was all gone because of what happened out in the city, and she could only give a shaking nod before running in the direction where Galladon and Samwell had come from.
~X~X~X~X~X~X
Not far from the gardens of the Red Keep, Tywin Lannister had narrowly avoided the pieces of burning hail as they fell down from the stormy sky above the capital. Now he was almost out between the flower beds.
"GRANDFATHER!"
The voice of Argella, wherever she was. But her calling on him was ear-piercing, and not scared or demure at all. Rather, she sounded like a younger, shrill version of Cersei when she had one of her childish tantrums in nearly the same age when they had witnessed that damn Martell woman marry Rhaegar sixteen years ago in front of the whole royal court.
"Tywin Lannister, come out at once and confess your guilt in this cursed turmoil! For this is your doing, no doubt, thanks to that you intended to murder Elia Martell and her children 13 years ago! You saw them as a threat to Mother having a chance to become Queen of the Seven Kingdoms, not even wanting the young Aegon to be sent to the Wall and Rhaenys to the Faith, because you saw their very survival as obstacles to your plans!"
How did she know that she had ordered Gregor Clegane and Amory Lorch to remove the Martell woman and her offspring that was in the way for Cersei to become Queen? That he did not want to see Aegon Targaryen use his maternal family as allies to reclaim the position as Crown Prince from a son between Rhaegar and Cersei, and that a married Rhaenys Targayren could bear a claimant to the Iron Throne thanks to who her father was? Then he heard his oldest granddaughter singing in a loud voice:
"As narrow-minded and presumptuous as you, Grandfather, I know no one who is. You seem to think you can commit crimes and then pretend that you had no share of blame at all! Now you see the overdue punishment sent by the Gods themselves! You are the one who will cause the very fall of House Lannister!"
That insolent girl! Too much of Robert Baratheon in her, Cersei failing to show her daughters how a lady should act and behave, and that useless septa allowing her to think that she could speak her mind whatever she desired!
But as he came out in the garden, ready to tear her brazen words apart with some well-chosen scolding or perhaps even a slap to her face, Tywin instead saw all of his royal grandchildren sans Myrcella and Tommen standing there, each one of them having a strange look in their eyes that somehow unnerved him deep down, as if they had expected him to take the bait.
"So...the butcher of his own bannermen, Houses Reyne and Castamere, finally shows his face."
More than ever, Lyonel indeed looked like a younger Robert despite the thinner face that came from House Lannister though Cersei, double so when Tywin spotted a smaller hammer held in his hand. What did that foolish brat think that he could do? Imitate his idiotic father and wish that all problems could be solved by fighting with a weapon in hand?
"There are some serious crimes for you to confess about commiting, grandfather, for we have seen all the evidence pointing straight at you. Your motivation? Making House Lannister the most powerful and feared House in all of Westeros, getting your own blood connected with the royal dynasty so no one could doubt the powerbase of yourself."
Already in a sour mood from the failed audience with Robert earlier, Tywin was really not in the mood to witness his grandchildren behave like this.
"Who has given you this foolish idea that I wanted that frail Dornish woman and her two brats dead?"
And then someone grabbed him from behind, holding onto one of his normally impressive sideburns that he had kept after shaving his thinning hair off, the other hand holding a sharp dagger to his throat.
"It is my late father's sole surviving sister-daughter, grand-niece and grandnephew that you tried to have murdered to clear the path to the crown for your own daughter, aka my own cousin and her children."
Tywin was so shocked that a woman dared to hold a weapon against him, that it took him some moments to connect the dots.
"Sister-daughter...cousin...you are a bastard of Lewyn Martell?!"
Holly had removed the veil from her head earlier to use as a improvised bandage on Sandor who had gotten a small rock on the burnt half of his face, and now, without all the white masking her appearance and her dark brown hair slightly loose from the tight braid, her face wore enough similarity to Elia Martell that there could be no doubt.
"Correct. Your grandchildren know what you tried to do towards my cousin over 13 years ago, and the motive to order the deaths of her and her sweet children was not that hard to guess as aunt Aria did tell Padre about you saying that your own Cersei was intended as a golden bride for Rhaegar. When that unfaithful inbred rat died at the Trident, Viserys would not be mature enough for marriage until another six years at the earliest and he was already a decade younger than Cersei, a time you did not want to waste. So you choose to make her the Queen consort of Robert Baratheon instead if he just could take the crown, hoping that Lyanna Stark would be kind enough to die in some manner that could not be connected to you, and try to remove all threats to that coming true!"
"You are lying!"
Seeds of panic and distress began to slip through the inner self-control of Tywin, given that Holly was now holding the dagger so close to the skin of the throat that he could feel that any wrong move could draw blood on the steel. Also, there was something strange with his grandchildren, their eyes were glowing with an amber colour.
"Not so enjoyable to lose all control over a situation and being the helpless one for once, right? Well, do not trust on someone to come and save you from facing the consequences of your many crimes, it is high time that you will have a proper taste of the same unpleasant experience that you have given to others."
But before Lyonel could take more than one step forwards, a strange cry was heard from the sky. Yet Holly seemed to realize what it could be, for she had heard it twice from the water mirrors when she had spoken with Elia in Rohan and her cousin had hurried to tell her what the sound was.
"My ever so clever changes," she addressed the young royals, "spread yourself out from each other and RUN like you had the hounds of the seven Hells chasing you!"
Thus Tywin found himself slammed face first to the stone steps of the small paths between the garden grass, as Holly and his grandchildren tried to escape the incoming arrival of Khamûl on his fey-beast.
"Finally I have found you...Lion Lord."
In the hand of the former Farao, was a large flail of steel, with metal studs on a iron ball hanging from a smaller chain. A deadly version of one half of the two symbols for his power as the ruler of Kemet.
~X~X~X~X~X~X
Perhaps as a reaction to the fact that the most feared servants of Sauron found themselves in Westeros, the magic of House Martell was acting wildly even without the Martell family members doing anything themselves. This also reached as far as their distant Baratheon kin.
"AAAAAAAH!"
Taking a large double flat hammer with him in case of needing to defend himself, Gendy had managed to take himself out from the shop of his master and up to the less crowd-packed slope of Aegon's Hill where the Red Keep was placed, but today's surprises did not seem to have finished yet. Out from a strange circle shape above the ground, did Lady Selyse Baratheon, her two daughters Shireen and Rhea, as well Mya Stone and Eric Storm fall out on the dry grass.
"Ow, ow…hey, how did we end up in King's Landing!? We were in the Great Hall of Storm's End mere moments ago when Master Cressen requested mylady to come and have the daily check for movements from your unborn baby!" Mya commented when she looked around to see that the surroundings had changed from indoors to outdoors. Sitting up with a groan as Eric offered to help her up, there was no mistake about that Selyse only had about three months left before the next attempt to give Stannis a son.
"The capital...what in the seven hells are THAT?!"
With one of the Nazgûl flying over, Selyse could be excused for freaking out when she too realized where they were now.
"Mya! Eric! My ladies!"
While not meeting the royal children that often, the Lady Baratheon of Storm's End knew them well enough to spot that this soothy-faced youngster, looking near identical to Lyonel but having a classical Baratheon strong, square jawline, had to be one of the royal by-blows because he was missing the clean-cut features and narrow, slanted eyes that the royal children had inherited from House Lannister, their maternal kin.
"Gendry!" Mya greeted her younger half-brother when he came close enough for easier talking, "do you know what is going on here?"
Recalling his manners at the last moment and giving a quick bow for Lady Baratheon, the blacksmith apprentice shook his head.
"No, but I know that the three ladies should be escorted to the Red Keep. The smallfolk are in chaos down in the streets further down and the fighting risks becoming ugly. It is not a suitable sight for a lady carrying a child or her daughters."
"We are no babies!" Rhea protested, making a scowl in the exact same manner as Stannis the few times that Gendry had seen him, though it naturally looked a little more funny with her young age and Targaryen appearance.
"Well, what are we standing here for? Come on! Let me do the talk if the King or my husband sees us," Selyse ordered, and Mya picked up her daughters while Eric took the lead towards the gates of the Red Keep, Gendry at the rear and holding a firm hold on his hammer, because he felt it was best to ready for defense in case someone saw the fine clothing of Lady Selyse and her daughters in the distance. Some thugs may think this chaos in the city as a perfect chance to rob anyone carrying signs of their wealth like fine jewelry and the sort.
Back in the royal gardens:
Even with the veil of septa Holly around his face to stop the bleeding from the burnt half of his face, Sandor knew that he had to find the royal children. The group had been forced to spit up as the large pieces of burning hail broke the fruit trees and even knocked a couple of stones out of the wall around the garden.
"Sandor, wait on us!"
So far, he had found Myrcella and Tommen hiding inside the small chamber where the water buckets were kept when not used, but the rest of the royal offspring was nowhere in sight. Granted, the gardens were huge, so there could be several hiding places he needed to check first.
"Hurry up, you two. We must find your brothers and sisters. And that quick-footed septa as well."
A loud scream of pain could be heard near the entrance. A grown man, so it had to be one of the guards or someone else in the servant staff, none of the nobles would be in the gardens as the court had originally planned for the ceremony in the Great Sept.
"Sandor…," Myrcella whispered with hesitation, "does not that voice...sound a little like grandfather?"
Lord Tywin? This made the last male Clegane stop for a moment. Sure, Sandor heard about his arrival by ship late yesterday night, but what happened to make him scream like he was the one being tortured?
Just as he had promised as a very faint echo of his paternal instinct to protect the missing daughter who had vanished so long ago, when finding out that Tywin was behind a murder attempt of the reborn Mara in her current life as Rhaenys, so did Khamûl not show any mercy against the current Lord Lannister as he let Tywin face the strength of his flail all over his body, not helping by that the father of Queen Cersei did not have any steel armour to protect him.
"Where is she? Where is Mara, the mother who gave birth to her current self and the boy she called her younger brother? ANSWER ME!"
Tywin had never been beaten in this manner before, not even by the master-at-arms as a boy when he got the necessary training to be a knight, because of his nigh rank by birth. As a result, this was his first taste of how it felt to be beaten with a real weapon, just like how a servant could face punishment for something they had done wrong.
"I said, where is she!?"
Even in his current fury, Khamûl made sure to not hit the head on the blond mortal. He needed the man alive, and would not get any answers if he died from a fatal blow to the head.
"Brother!"
"Tywin!"
On seeing the similar blonde hair on Kevan and Genna as they came running, with their own families not far behind, the second most powerful Nazgûl got an idea to try making Tywin tell where his reborn daughter could be.
"My youngest Consort said something about you having a favorite song, to remind people of how you drowned some of your followers as punishment for a revolt…"
Using his control over sand and making his fey-beast fly down to the harbour with the injured Tywin in the claws, Khamûl captured everyone who had a similar scent as Tywin:
His two remaining siblings who still lived, their respective spouses, children and even Genna's two small grandsons from her oldest son Cleos. Myrcella and Tommen were dragged away from Sandor before he could stop it. Even Cersei was grabbed and carried by the sand all the way from the ruins of the tower at the Sept of Baelor where she had been kept locked up in her madness.
"Grandfather Tywin!"
On the banks of the river following the city walls, Khamûl raised several meters of thick glass that he crafted with the sand from the river and sea. At the very bottom, Cersei and Emmon Frey, the husband of Genna, landed in two separate parts before a roof was sealed over them. In the levels above, the terrified Myrcella and Tommen, then seven of their mother's cousins, the four sons of Genna and Kevan's three sons Lancel, Willem and Martyn. Then, above them, Kevan's wife Dorna and infant daughter Janei.
"Kevan! Boys!"
At last, Kevan and Genna themselves at the top with the surrounding glass walls so high up that they could not climb out, then Khamûl dumped Tywin down in a circular chamber as a central point, where he could see all of his imprisoned relatives around.
"Uncle Tywin, help!"
Using his magic again to make several musical instruments float in the air around the prison of glass, the former Farao would have smiled cruelly if he had a face of flesh and blood visible below his black hood.
"Perhaps this will loosen your tongue about where Mara is. To see your own family drown and be unable to prevent their deaths!"
Water from the Blackwater Bay began to flood into the glass chambers of Cersei and Emmon through a small hole that would not break the thick glass walls, and for the first time in his life as he realized what would happen in front of his own eyes wíth all the relatives trapped so he could see their deaths, Tywin felt horror at the tune that signaled the start of "The Rains of Castamere", the very song he had commissioned so long ago, which immortalized the destruction of House Reyne of Castamere by him during the Reyne-Tarbeck revolt.
"Tywin! Tywin, HELP!"
Even Genna and Kevan realized the meaning of the song being played at this very moment, screaming for help and slamming their fists against the glass walls in growing panic as the water began to rise very quickly, Cersei and Emmon already having water halfway along their bodies with no way of escaping their incoming deaths when their small chambers was filled. House Lannister would indeed meet their doom by water, just as the members of House Reyne as they were drowned in the silver mines below their seat Castamere.
"Tywin!"
With a cruel laugh over the scene in front of him, Khamûl left the Lannisters behind to find the royal children, their baseborn half-siblings and their cousins from Storm's End, following the scents that they still had from their past lives as his own children.
~X~X~X~X~X~X
Author note: As Galladon is still alive in this AU and Brienne is not the sole survivor of the four children of Selwyn Tarth, he obviously would need a betrothed to become his eventual wife, and I chose Myranda Royne because she would be only three years younger than himself. Not all noble girls in Westeros would be married off at a early age in a arranged marriage, some may be older teenagers when the wedding is being hold
I headcanon House Lannister to have clean-cut features in the form of sharp and edgy lines on their faces, with narrow and slanted eyes alongside sharp noses, basically a little like a cat's face to suit their lion symbol.
About Tywin not being punished much in his life: as a noble his social rank exceeded that of his tutors, and Aegon III had to witness his commoner friend and cupbearer Gaemon be used as a whipping boy for his early failures in the cruel master-at-arms Ser Gareth Long's standards
