*I don't own any of the Kingdom Hearts characters, I only own Katie/Tiaxek/Katie-Vanitas

It was cold…much colder than usual. Vanitas groaned and slowly opened his eyes, but unlike his fimiliar farm-like surroundings of Katie's heart, it was completely black. Vanitas shot up in alarm and looked around. "Katie, what's happening?" No response came from his host, making Vanitas go into somewhat of a panic. Thinking quickly, he opened the portal to Katie's Station of Awakening. Once he got the the Station, his eyes widened from what he saw. Katie's Station of Awakening was turning black and deteriating, just like Katie's heart. Vanitas mentally slapped himself, why he leave Katie alone at Castle Oblivion?

"V-Vanitas…?" A voice came from the black void. "Is that you…?"

Vanitas eyes darted towards the voice and his eyes widened, it was Katie. She was at the center of the Station and half of her body was gone under a blanket of shadows, her eyes were extremely dull and her breathing was laybored. Vanitas made his way to her as he asked, "What's going on, Katie?"

"Xehanort…he's taken over me…" Katie gasped between deep, jagged breaths.

Vanitas' eyes narrowed at the mention of his former Master's name. "Xehanort?" he repeated.

Katie nodded and motioned her head at the darkness. "This is his darkness, it's too strong…I can here it attacking my friends."

Vanitas kneeled down to Katie and examined her, her face was deathly pale and had sweat run down from her forehead. "Does he know that you're still here?"

"I don't think so…it keeps saying that my heart is gone…" Katie looked up to Vanitas with fear in her eyes. "I'm starting to believe it."

"Your heart isn't gone. Not yet." Vanitas thought for opions then he asked Katie, "There's only one way to get out of this, Katie." He got up and wielded his Keyblade and pointed it at Katie. "Katie, is there anymore Light here?"

Katie thought for a second then slowly nodded, with a sluggish hand, she pointed at herself then Vanitas. "We're all that's left…"

Vanitas stared at her. "Me? I have…Light?"

Katie nodded. "Xehanort might have told you that your…pure darkness but…you have been in my heart for so long…"

"That I've been influenced by your Light…" Vanitas finished for her. After being in deep thought he assured Katie, "You're going to be okay, Katie. I promise. I have have been in your debt for years and I'll start returning it to you now." Katie smiled weakly at him and her eyes fluttered shut, she slipped into uncousiousness. Vantias took in a deep breath and raised his Keyblade high, with a yell, Light as well as some Darkness streamed out of his chest and formed as an orb on his Keyblade's tip. The orb shot off of the Keyblade and rocketed towards the sky and exploded, shattering Light and Darkness and making it rain down. Each drop of Light that touched Xehanort's Darkness evaporated the shadows. Vanitas pointed his Keyblade at the ghost-like form of Katie and with high concintration, he made Light shoot out of her chest. Vanitas contained Katie's Light into an orb and made Darkness come out of his chest, forming the Darkness into a sphere. With the two spheres, Vanitas conjoined them. A large shockwave exploded from the two orbs, Light and Darkness shot rapidly in all directions , destroying Xehanort's Darkness with each conjoined beam. The Light-and-Dark orb shot to Vanitas' hand, making it glow. With his other hand, he gripped onto Katie's wrist and closed his eyes. He felt his Keyblade disappear from his hand and was slowly replaced with a much heavier weapon. He felt his being merge with Katie's and let out a pain-filled yell. He and Katie disappeared with a flash of Light and Darkness.

The Xehanort's appeared through dark portals as soon as they felt something unbalanced in their order. They looked at the ground to see Sora and the Keyblade Wielders unconscious and have smoke roll off of their bodies. Their gazes stopped when they saw Tiaxek on the ground near the young Keyblade Master, Riku. Master Xehanort's eyes narrowed when one of Tiaxek's silver locks turned to jet black then widened when Tiaxek started to glow with an aura of Light and flames of Darkness. Her limp body lifted off of the ground and rose up to the ceiling, her aura glowed brighter. Seven of the Keyblade Wielders also started to glow then Light shot up towards Tiaxek from them. Darkness formed off from the surprised Xehanort's and also conjoined with Tiaxek. Her body was no longer in sight because the bright aura. The figure lowered back to the ground and it suddenly broke off its light with a sonic boom. Tiaxek was no longer there. In her place was a teenage girl that had jet black hair tipped with platinum blonde. She was wearing a red and black organic body suit that had boots to match. Around her waist was a ripped-up red half skirt that was open in the front and faded to black, the only thing that keeping it from falling off were two intersecting red belts. Hooked to one of the belts was an orange charm made of glass and gold metal. Jagged dark silver metal outlined her jaw. Her skin was two shades paler and had one deep blue eye and one gold eye behind silver square-shaped glasses. In one of her hands was an extremely large Keyblade, bigger than its wielder in fact. It was made with two crossing Kingdom Keys, with the teeth facing outward and greenish-blue that faded to yellow filigree came out of the crossing Kingdom Keys. Out of Kingdom Keys was a long gold blade that faded to white as it got closer to its tip. Its Keychain was a black and red heart that is similar to the Heartless symbol, only without the fleur-de-lis bottom and jagged cross, with two Kingdom Keys crossed over it. The chain started out as two separate chains that form into one: it was the χ-blade. The girl looked up blankly at the Xehanorts.

Master Xehanort growled when he recognized the girl, "You fool…Vanitas did you think you could forge the χ-blade on your own accord without your two hearts being synchronized first like yours and Ven's were since the used to be one...and now your mistake has fractured your heart, hasn't it? But if you're still awake enough, I'd like to know how you're still to be from the girl. You should've been broken down and became a part of her powers..."

Katie-Vanitas looked at the ground. Then slowly she put on an insane smirk and made crazed laugh, surprising the Xehanorts. "You kept telling Katie how she had been marked by the path of Darkness since she met me when she was four…now let's think real hard about that. After dwelling in the same body for so long how would our hearts not be synchronized? And as for you having thought I broke down into her powers earlier…are you blind?! The Unversed are shaped by my feelings since they are my emotions if they became Katie's emotions they would change shape to reflect what she feels. She can only command them because I am with her. Oh well. The time for explanations is over so sorry but I've got somewhere to be."

The Xehanorts wielded their weapons. Master Xehanort spat, "You are not going anywhere, Vanitas…"

Katie-Vanitas scoffed and shrugged her shoulders. "Ugh. Fine, fight to the death coming up." She threw the χ-blade at the ground. "Wakey-wakey." Light shot off of the Keyblade and went to the Keyblade Wielders on the floor.

Groans rose from the Keyblade Wielders as they slowly stood up. They all saw the Xehanort's and wielded their weapons. Sora saw Katie-Vanitas in the corner of his eye and grinned. "It's Katie!"

The group turned their heads to face Katie-Vanitas. Ventus growled at her. "Vanitas!" He charged at her.

Katie-Vanitas blocked Ventus' attack effortlessly and pushed him away. "Idiot. I'm not the enemy!" She hissed. Terra and Ventus jumped at her voice.

Riku quickly explained to Terra and Ventus, "Katie carry's Vanitas' heart! He protects her in fights!"

Terra's eyes narrowed at Katie-Vanitas then joined besides her. "If you pull anything…"

"Trust me, I'm not going to." Katie-Vanitas assured him. The rest of the Keyblade Wielders joined Katie-Vanitas. She pulled the χ-blade out of the ground and pointed at Master Xehanort. "You've been around for too long, old man." Unversed shot out of Katie-Vanitas and surrounded the Xehanorts. "Attack." Everyone lunged into battle.

Question Time!

The FF member lapina-theobserver asked: "What if Terra had a secret younger (due to time flowing differently on different worlds) twin sister?" Hmm...(Looks at Katie and grins evilly)

Katie: NO! Big N-O! I know what your thinking but the answer is no, Katelynn!

Me: DX Well, there goes that idea. But yeah! Sounds like its possible to me!

Got anymore questions? Ask me in a review!

Big thanks to tsukuneXmoka for giving me the idea for this chapter! ^-^ Oh and before you ask, the beginning of this chapter took place in Katie's heart/Station of Awakening then it went to Castle That Never Was.
