The group fought hard against the fiends that waited inside for them. They were glad for stocking up on potions before they left, they almost lost Rikku twice. "Are you all ready?" Yuna asked, staring at the group. "Fight hard, give it your all." With that said, she walked with the group up the stairs to encounter Seymour.

"You again, ya?" Wakka snarled.

"You're still here?" Seymour sniffed the air. "Ah but I can tell it's taking over, Sir Auron." He giggled that evil giggle, "Sin and I are one. And together we shall rise to power and take over all of Spira!"

"Shut up! Why did you kill Kimahri?" Tidus regaled, stepping forward menacingly.

"I didn't kill Kimahri."

"YOU LIE!" Wakka clutched his blitzball ready to strike.

"No I do not lie."

"How can we believe you, ya? You murdered your own father, ya? You slaughtered most of the Ronsos, ya? You wanted to end Kimahri's suffering, ya? YOU KILLED KIMAHRI!"

"No…I didn't. Auron did. The smell of Ronso blood is strong on his coat." Seymour simply laughed, as Lulu stepped forward.

"Enough Wakka. Seymour you will pay, first Kimahri and then the priest. Who else have you gotten under your guado fingers?"

"Hmph…Don't listen to me. Are you here to end your suffering?" Seymour drummed his clawed fingers together.

"Prepare to die." Auron felt himself lose control, and his eye dilate. He felt his jacket tug just a little bit, and realized Wakka was standing on a loose thread from his jacket. The realization hit him like a ton of bricks, he shook himself from this reality and cut the string with his Masamune, confusing Wakka. He waved for Seymour to attack him.

"You show you're true self, you fiend!" Seymour laughed, and began his transformation into Seymour Omnis.

"What is he talking about?" Yuna asked confused.

"We'll explain later, we have a Guado to send." Rikku, jumped into the battle that had already begun. Auron was charging furiously and slashing randomly at the Guado. "I'm here for you too, Auron!" Rikku charged and attacked the larger fiend.

"You won't get away with this!" Yuna cried and summoned Anima.

"You send my own mother, to end my fate?" Seymour laughed, as he quickly struck the Aeon dead. Yuna cringed as she was struck back by Seymour's attack.

"BEGONE!" Lulu cast Ultima on Seymour.

"Just a mere scratch!" Seymour snarled, and knocked Wakka's blitzball back towards him. The battle continued for twenty minutes, the only real connecting blows were from Auron. "Yuna…I figured it'd always be you to send me." He fell to his knees back into his demi-guado state. Yuna began to dance to send Seymour's damned soul to the farplane. Auron fell to his knees breathing shallowly, his eye were completely black.

"Auron?" Rikku knelt before Auron, watching him. He glared at her, his hands digging into the dirt.

"Get away Rikku."

"No. Auron." Rikku wrapped a frail arm around her.

"Get away!" He struck her backwards, "NO!" He snarled as if he were hit in the face, "Please, leave me."

"Sir Auron, what is going on?" Lulu advanced towards him.

"You stupid little…" Auron rose quickly and charged Lulu, his Masamune almost piercing her skin.

"Enough, Auron!" Lulu stepped to the side avoiding the weary warrior's attack just barely.

"Sir Auron!" Yuna cried out, watching him fall to the ground, his chest was heaving.

"What's going on? Has Auron lost his mind, ya?" Wakka, stepped back gazing warily.

"Auron?" Tidus stepped forward, only to be struck in the head with the butt of Auron's Masamune.

"What is going on?" Yuna demanded, and stared at the fallen teenager.

"Auron is turning into a fiend."

"No!" They all cried out at once, stumbling backwards.

"Rikku, help me…" A strangled voice murmured from a shuddering body.

"Auron…" Rikku crawled towards Auron. "I told you I'd help you."

"Get them away from me." Auron motioned towards the confused party. "Too soon, too soon." He mumbled.

"You killed Kimahri." Lulu spoke with a sudden realization. "The priest didn't attack anyone, you killed him yourself. Rikku why did you hide this from us? Sir Auron why?"

"I…I…" Rikku stammered, Auron roughly shoved her away. She tumbled into Wakka's legs, knocking him down.

"Come on, old man!" Tidus bounced on the balls of his feet.

"Get away!" Auron cried out with a twisted and tormented voice, he threw his Masamune away from his reach, before he could do anymore damage. "Yuna, send me!" Auron pleaded, a lone tear ran down his cheek. "Before I kill any more innocents. Before I become a…" A low growl came from deep within his soul, the demon was slowly clawing itself free from its cage. Yuna hurriedly began to dance, tears flowing freely from her eyes.

"Too many died this week. So many poor lives lost." Lulu wiped away a tear from her own pale cheeks, "Sin has taken so many innocent lives. We will defeat him." Lulu watched the pyreflies that danced around the fading guardian.

"Auron…Tell daddy I said hi." Yuna sniffled and finished the last part of the dance.
