Hello!

New story from me (I haven't forgotten about my other stories!) which takes the elemental bending abilities of the Avatar: The Last Airbender universe and sticks them into the universe of Game of Thrones.

Story starts with Robert's rebellion but will jump around in terms of timelines and characters and is not intended to be a massive detail orientated novel but a bit of fun for me to play around with :D

Important Info before you start:

Water – North (Starks) Riverlands (Tullys) Iron Islands (Greyjoys)

Earth – Westerlands (Lannisters) Reach (Tyrells)

Fire – Dorne (Martells) Crownlands (Targaryens)

Air – The Vale (Arryns) Stormlands (Baratheons)

Most nobles will have bending powers with some 'commoners' having the abilities too but the most powerful noble families tend to have the stronger bending abilities in this universe.

Also, words in italic are normally a character's internal thoughts or I am putting extra emphasis on a word to draw your attention to it.

Chapter 1: Clash of the Elements

Year 281 AC

The Battle of the Trident, On the Trident, central Riverlands

Catelyn watched as her newlywed husband and a contingent of northern water tribesmen charged towards the raging storm in the centre of the battle field. Catelyn had no doubt who was generating that storm. Robert always liked to be in the middle of the fighting. She looked above her to see Jon Arryn and the Knights of the Vale floating in the sky on gliders. Catelyn presumed Jon Arryn was orchestrating the battle tactics of the rebel forces as he observed the balance of the battle from above and was waiting for the perfect moment to unleash the Knight of the Vale onto the field of battle.

Her eyes were drawn to the sparks of fire that were being buffeted in the wind and the occasional cluster of earth that was being thrown around the battlefield in front of her. The combined forces of the Dornish, the Reach, the Westerlands and the Crownlands led by Rhaegar Targaryen outnumbered the rebel forces of the North, Stormlands, Riverlands and the Vale but Catelyn knew that their side possessed the more hardened soldiers and the superior benders if the raging tornado in the middle of the battlefield was any indication.

Suddenly she felt the ground beneath her feet shake. It seemed that the Tyrells and Lannisters had had enough of Robert's tricks and were literally breaking apart the battlefield.

Catelyn smiled. This action was a mistake.

Where the earth split the gap was filled with water. Fighting so close to the Trident was to the rebels' advantage. Specifically, to any water bender's advantage. Catelyn felt the water surround her and empower her. This served to fill her with courage and she knew it was time to join the fray.

Her eyes scanned the waterlogged battlefield to spot her father, Lord Hoster Tully fending off a few dozen earth bending Westerland Lords. Catelyn gathered up enough water beneath her feet and rode her own self-created wave to reach her father.

As she reached halfway towards her father, she suddenly had to swerve to dodge a large fireball. It only just missed her and Catelyn could feel its heat on her face as her wave broke down and she rolled on the ground. In the next instance she brought up a shield of water as more fireballs came her way. All of them were extinguished as they made contact with her shield.

"Lady Catelyn, I presume," came a rather charming and exotic voice.

"Yes, and who are you?" Catelyn replied not taking her eyes of the tanned man who she noticed was wearing the white cloak of a Kingsguard.

"Prince Lewyn Martell," the Kingsguard answered as he gave a little bow before kicking a few fire arcs towards Catelyn that slashed into her water shield.

Catelyn regrouped her broken shield into a dozen ice shards which she propelled toward the Dornish Prince.

The sun kissed man easily danced around the shards while sending back a few shots of fire as he closed the gap between the two combatants, running at Catelyn.

Catelyn took a step back before concentrating. Anything I throw at him he will dodge, she deduced from what little she had seen of his fighting style. Prince Lewyn was extremely mobile, emulating an air bender's fighting style.

With this in mind she decided to limit his mobility. She raised her hands and the Dornish Prince suddenly halted and fell to the ground. His feet where now encased in ice as was most of the area surrounding him.

Catelyn smiled; it had taken her weeks to master turning such a volume of water into ice instantly. She further moved her hands in a flowing gesture as the Prince tried to thaw his feet out of the ice but the ice only grew up his legs to start to cover his torso.

He started to panic and tried to burn himself out of the encasing ice but Catelyn held firm and concentrated on growing the ice around him. Her hand gestures and movements became quicker and more energetic as Prince Leywn fought to keep the ice from covering his face but it was a battle he was losing. Catelyn was free to move fully and execute her moves while Prince Leywn was not.

After a further minute of struggle the Prince was fully encased in ice and Catelyn could see his face frozen in terror behind the ice as he suffocated to death.

Catelyn let out a tired breath and supressed the emotion of killing a man deep down into her mind. She looked around the battlefield. The Royalist forces were being pushed back so that she was now surrounded by mainly Arryn and Riverland soldiers, and Prince Lewyn's frozen body.

She looked further afield and saw her father was now engaged in one-on-one combat with a red armoured earth bender.

It looked like Lord Tywin Lannister had gotten tired of her father killing his Lords and was now dealing with the rebel River Lord himself.

A pang of worry embedded itself in Catelyn's heart. Lord Tywin Lannister was a renowned earth bender who had singlehandedly turned the tide of the War of the Ninepenny Kings to King Aegon V Targaryen's favour twenty-five years previously.

Her father looked to be on the defensive and Catelyn rushed to his aid on a wave of water. She reached her father just in time to deflect a boulder of earth with a strong pool of water.

"Catelyn, I told you to stay with Lord Arryn," Hoster Tully puffed at his daughter.

"And I told you not to get yourself killed," Catelyn shot back while watching the movements of Tywin Lannister who was equally noting her appearance on the battlefield.

The ground rippled towards them and father and daughter both elevated themselves enough with steps of water to avoid the rocks that jutted out of the ground where they had been previously standing.

"How about we work together?" Catelyn suggested as she gathered water towards her arms and extended the water outwards to act like elongated swords.

"You leave me with no choice," Hoster replied gruffly annoyed his daughter was in danger but had no way to force her to leave and no time to convince her to as more chunks of earth were thrown in their direction and followed up by Lord Lannister riding towards them on rapidly moving earth.

Once he got near, he sent stacks of earth shooting up out of the ground forcing Hoster to shield himself in an ice ball.

Earth smashed into ice.

The protective ball was beginning to crack under the pressure until suddenly the earth stopped pushing. Hoster returned the ice to water and saw his daughter swiping at the Lion of the West with her elongated water swords. He went to help but Tywin, with a wave of his hand created a high barrier to sperate him from them.

Hoster turned away from the newly formed earth bund to see a mix of Dornish and Reach men standing in front of him. He raised his hands ready to do further battle, hoping his daughter would be able to hold her own against the might of Lord Lannister.

Tywin's attention narrowed on the young red headed water bender in front of him as he launched another set of rocks in her direction. She already wore the colours of House Stark and favoured the famed Tully looks. Her face betrayed the amount of effort she was exuding as she avoided the thrown pieces of earth and danced into an offensive position turning her elongated water sword into a flurry of ice shards.

Her ice shards were ineffectual against his defensive walls, barely leaving a mark.

Time to test her defence, he thought relishing the challenge.

He hadn't had much contact with Lady Catelyn, only knowing that she had been recently married to the North Water Tribes Chieftain Eddard Stark thereby uniting the Southern and Northern Water Tribes in marriage and aligning them politically with Houses Arryn and Baratheon. But she was lasting longer than any of his previous opponents he had encountered on the battlefield. Tywin mused that this was down to her incredibly defensive style of fighting.

He moved his arms and hands in an upwards motion and watched as Catelyn avoided the rocks that burst up from the ground with flowing water bending that allowed her to roll off the protruding earth with a buffer of water surrounding her.

She tried to set up her own attacks but the rapid amount of rocks she was having to avoid took all her attention. She was constantly having to move making it hard to form an attacking stance.

I can't win this fight if I can't hit him, Catelyn told herself.

Catelyn had to risk an attack on Lord Lannister or he was going to be able to wear her down and pick her defence apart.

So, she dug her heels into the soaked ground and with all her strength sent a full building tall tidal wave of water towards the opposing Lord.

This was her mistake as a human sized boulder smacked right into her immobile stance and knocked her out cold.

Her tidal wave continued though.

Tywin was able to ground himself in a box of earth as the wave rode over him but his men were washed away behind him in the rolling wave that dispersed as it went across the battlefield.

Tywin unearthed himself to see Lady Catelyn laying on the ground a dozen metres in front of him unconscious. He walked slowly to the defeated Lady and looked down at her. She didn't appear to have any broken bones and was still breathing in steady breaths. She was covered in muddy water and her hair stuck to her cheek but there was a sense of peace about the sleeping Lady that conflicted with the raging horror that surrounded her.

Tywin called for his men to take her back to their camp. She would be a valued prisoner if the war was not decided today.

Ned cut down a Tyrell solider who came towards him with his ice sword and glanced towards his best friend. Robert was enjoying blasting his way through the scores of men surrounding him. Ned had lost count of the many times an enemy solider had landed next to him having fallen from a great height. The battlefield was littered with broken bodies of Robert's victims.

Ned turned to see one of his men scream in agony, the area where the man's heart should have been was replaced by a piercing rock formation and behind him was a blond lady holding a menacing smile.

"Lady Cersei," Ned greeted coldly aware how many people the fair woman in front of him had killed.

He tightened his one-handed grip on his ice sword as he raised his other hand, ready to respond to any aggression from the notoriously vicious earth bender that stood before him.

They both tensed ready to unleash their attacks when a horn sounded.

Cersei hesitated, which let Ned launch a barrage of water jets at her person which she blocked with a swipe of her hand, raising up a pile of rock.

When Ned flanked the defensive structure, Cersei had put up he found that she wasn't behind it but had retreated.

Strange, Ned thought, until next time my Lady.

Cersei wasn't known to be shy for a fight. Then he realised the sound of the horn was the sound for the royalist forces to retreat. And there was only one reason to retreat if the battle was still being evenly fought. A commander had died.

Rhaegar Targaryen must have fallen.

Ned attempted to muster his men to follow the retreating Lannister, Tyrell and Crownland men but a large wall of earth shot up out of the ground to cover their retreat.

No doubt the work of Olenna Tyrell and Tywin Lannister, Ned thought as they were the only two earth benders known to be capable of such a wide-ranging feat.

Author notes:

In this AU the Lannister forces were present at the Battle on the Trident. Robert, Ned Catelyn are all late/mid-teens right now with, Cersei being I think two years younger, but capable fighters and leaders. Hope I am merging the bending in okay with the battle dynamics.

Let me know your thoughts :)

Prince Lewyn Martell (Catelyn was able to encase him in ice and suffocate him)

Prince Lewyn Martell is Doran Martell's Uncle and I know he was a Kingsguard so would have been a very formidable warrior but he was a fire bender surrounded by loads of water. Catelyn is no pushover and had the environmental and elemental (Water vs Fire) advantage so I went with her defeating Lewyn quite resolutely.

Prince Rhaegar Targaryen (Robert defeated him during the Battle on the Trident)

Rhaegar still dies in this story and I like to think he gave Robert a run for his money but that Robert (in his prime) would have been able to dodge most of the fire attack from Rhaegar with ease (Airbender) then with a full gust of wind behind him smashed into the Prince with his war hammer at full speed crushing his lungs.

Next Up: The repercussions of Rhaegar's death are felt in King's Landing while Catelyn finds herself the prisoner of the Lannisters.
