Prologue/Chapter 1: The Kraken's Doom

Year 289 AC

End of the Greyjoy Rebellion

Great Hall, Pyke, Seat of power of House Greyjoy in the Iron Islands

Eddard Stark bashed through the heavy wooden door as his men rushed forward to subdue the Ironborn. With their superior numbers the struggle didn't last long, and he watched in silence as his men manhandled Balon and Euron Greyjoy to the ground. Unsurprisingly, it took five of his men to tie up Euron; he was a much fiercer fighter than his brother. Most Ironborn had fought back and died; few surrendered, and the Great Hall was littered with dead bodies.

All this death could have been avoided if Balon Greyjoy had just been content as Lord of the Iron Islands instead of raiding the western coast of Westeros. Even then, it might not have escalated to a call to battle if Euron Greyjoy hadn't kidnapped Alyssa Arryn. As the oldest daughter to Jon Arryn she was as good as a little sister to Eddard, and was to become his actual sister in-law by marriage to his younger brother Benjen. The guilt of being responsible for her when she was kidnapped had been gnawing at Eddard ever since she had been whisked away from the North.

More men spilled into the Great Hall, baring the sigil of House Arryn. Eddard gave them a nod before announcing that the Greyjoys were to wait for the King to pass judgement. It was his duty to hold the captives until Robert arrived.

No doubt Robert was enjoying himself on the battlefield, thought Eddard.

Eddard's attention was drawn back to Euron Greyjoy as the Ironborn started laughing manically at something over his shoulder. Eddard was about to order he be gagged when an arrow whistled past his ear and embedded itself in Euron's midriff.

Eddard whipped around with his sword drawn to see Alyssa Arryn advancing on Euron, another arrow at the ready.

No, this isn't Alyssa. This is her twin, Kenna, Eddard realised.

Eddard yelled for Kenna to stop, but she released another arrow without pausing her advance. This one found its mark in Euron's shoulder. Eddard reached out to to grab Kenna as she walked past but found Benjen blocking his way.

"Let this happen brother," Benjen implored. "He deserves this."

"He deserves the King's justice, which requires the King to pass sentence," Eddard said dutifully.

"We found Alyssa, she … Euron hurt her, brother … Euron raped her," Benjen said quietly, his voice full of emotion.

Eddard stilled at his words and looked towards Kenna. She was Alyssa's twin. He couldn't even imagine what it must be like to see your own likeness in such pain. Eddard remembered finding his own sister in a similar state. Now he understood the fury in her eyes as she released her third arrow. It struck Euron in his upper torso.

Throughout the encounter Euron hadn't stopped laughing. His voice rebounded off the walls of the Great Hall, making it sound like there were multiple Euron Greyjoys taunting them.

"You look so like your sister," Euron slurred, "except for that look of fear I gave her. You don't have that yet, but don't worry someday someone will break you too," Euron promised while spitting out blood.

Kenna was now only a few metres away from Euron. She shed her bow and arrow-empty satchel, only to replace it with a gleaming dagger. She ran the last few steps and lunged.

Kenna plunged the dagger into Euron's body, forgoing the cool, calculated accuracy with which she had handled the bow. Euron continued to laugh, which only fueled her anger. She didn't stop when blood splattered across her face and started to soak into her clothes, or when Euron stopped laughing. Nor when he stopped breathing. Only when a hand grabbed her raised arm did she turn and meet the concerned eyes of Eddard Stark; the man she looked up to like a big brother.

"Enough", Eddard said softly.

"Do you know what he did to Alyssa?" Kenna said between gulping breaths, still straddling Euron's dead body.

"Yes, I have sent Benjen and a few trusted men to escort your sister back to the ships." He paused before adding quietly, "I think you should join them and return to the Vale."

Kenna nodded in acquiescence.

"Fine, but first I need proof to show my sister that Euron Greyoy is dead and can't hurt her anymore."

Eddard stared at her for a few moments, his eyes not leaving hers. She glared back at him with determination written all over her face. Eddard would not stop her. He released her arm and stepped back, taking care to avoid the pool of blood seeping from the corpse.

Kenna positioned the dagger at Euron's throat as her other hand moved to grasp the top of his head. She pushed down with all her strength and after a few dozen slashing motions his head was severed from his body.

Kenna stood up and held Euron's head in her hands staring into his lifeless eyes. Balon Greyjoy was still kneeling on the ground with his head forcibly bowed in defeat, and while he showed no acknowledgement to the death of his brother, his eyes held a burning anger that promised retribution no matter how long it took.

Kenna backed away from Euron's body, his head hanging limply at her side. The blue cloth of her battle garment was fully soaked in blood, and red lines streaked across her face to hold bits of dark brown hair to her cheeks. But it was her eyes that worried Eddard the most. The feral, uncontrollable rage was clear to see, and he was sure his men were giving her the same look of caution he knew was on his face.

"I want the crew of Euron's ship too," Kenna said coldly.

A couple of Arryn men within hearing distance hastily bowed in acknowledgement and gathered all the survivors bearing Euron's sigil. Kenna, flanked by Arryn guards, followed them out of the Great Hall, leaving bloody footprints in her wake.

Eddard could only stare at the bloody trail and the now headless Euron Greyjoy. How was he going to explain this to Robert?

He needn't have worried. When Robert finally made it to the Great Hall, followed by Jamie Lannister and a small army, he simply bemoaned missing the carnage.

"I would have paid good money to see Kenna take that fucker's head off!" Robert roared, slapping Ned good naturedly on the back. "You know if she hadn't killed him I would've stung him up by his balls until he begged for death!"

Eddard didn't respond.

"Now, what shall we do with the rest of the Greyjoys?" Robert said, looming over Balon and his two remaining children.

Author Notes:

Hey everyone,

Hope you enjoyed the prologue! There is a lot more to come.

Main aim of this story is to answer the question – What if House Arryn had agreed to fight with the Starks in the War of the Five Kings?

I really didn't want to input my own character into the story but I didn't think there were any Arryn characters that could hold the story together and take it in the directions that I want to go in.

I know my OC here doesn't really utter many words but actions speak louder than words, right?

This story will be following cannon loosely until the latter episodes in Season 1 on the TV show then it is an AU. The story takes its sweet time ramping up to the action and intrigue after this prologue but I think scenes have to be earned to be believable and this is going to be a long story

I am finding the writing process really fun but I am still new to the whole community so any advice and thoughts are welcome

Let me know your thoughts! Please review!

Information for the series/novel

This whole story will have three distinctive arcs. All three arcs will be contained in this story/publication and I will just fiddle with the tags when necessary.

Also although reviews are great (seriously they are amazing to get) I don't write for them so this story will steamroll its way to an end regardless of if it get reviews or not. I write for fun and all the cool situations I can put G.O.T characters through.

Cheers,

R.M
