When we are older you'll understand
It's enough when I say so
And maybe some things are that simple

Xehanort, exhausted from fighting Terra, falls to his knees while leaning on his keyblade for support. As Terra comes closer, the ground begins to shake and Xehanort grins, noticing the light shooting into the sky behind Terra.

"There, you see?"

Terra hesitates to turn his attention away from Xehanort, but eventually turns and notices the light.

"The x-blade has been forged!"

"Ven!"

"And now, Terra, it is time for the final union!"

Xehanort lifts his keyblade to his chest and pulls out his heart before he sends it to Terra to merge with a younger and stronger body.

"I swore I would survive and be there to see what awaited beyond the Keyblade War!"

"Terra, watch out!"

Nova stands on shaky legs and stumbles to Terra and activates his suit plate, transforming his clothes into his armor, but it was a second too late. Xehanort's old body began to dematerialize as Terra began to shed his armor and, to Nova's despair, revealing his white hair and yellow eyes.

"This heart belongs again to darkness."

Summoning the keyblade that belong to the old Xehanort, he turns to take in the weakened Nova behind him.

"Terra, you can still fight him. You have so much light in your heart," Nova cries, putting her hands on his chest.

Xehanort's eyes drink in Nova, watching the blood drip down her body and trail across her clothes. Nova continues to plea with Terra to come back and fight against Xehanort. Finally, he raises his hand and cups her cheek, softly whispering her name. Nova's eyes widen, hope filling her as she saw he was winning against the evil man. Xehanort smirks, raises his hand to summon his keyblade and then plunges it through Nova's chest.

"Love is weakness. Your part in this orchestrated plot is over."

With those words, he pulls his keyblade free and shakes the blood from it. Falling to her knees, she takes one last breath before she drops to the ground; her blood covering the dirt beneath her. As he begins to walk away, the area encircles him within a Will's Cage and when he turns, he sees Terra in his battle armor.

"Your body submits, your heart succumbs- so why does your mind resist!?"

Terra rises to his feet and charges at Xehanort with a brutal attack. At the last second, he dodges out of reach and retaliates before Terra can regain his footing. His life begins to quickly deplete as Xehanort's attacks never cease until Terra is able to quickly slip from his range. As he attempts to recover, Xehanort thrusts his keyblade in an upward motion and the ground rises up to heave Terra in the air. Before he can fall back to the ground, Xehanort launches darkness orbs at Terra; luckily he was able to glide away in time.

As soon as he swiftly dodged the last orb, he sliced his keyblade across Xehanort's chest and released a furry of damaging attacks until finally, Xehanort dropped to his knees before finally collapsing onto his back. Terra drops to the ground after Xehanort and suddenly a bright light begins to envelop the battlefield.

"Nova, I'm sorry I couldn't protect you. I love you."

As he whispered those words, tears freely dripped from his chin and the white light engulfed his body as well as Xehanort's. The last thing Terra saw was a brief glimpse of Ventus, followed by Aqua, and then Nova, with a bright smile full of love on her face.

"Aqua, Ventus, Nova. One day I will set this right."

The light from Kingdom Hearts begins to fade as Aqua and Ventus successfully defeat Vanitas below and destroy the x-blade.

Where fears and lies melt away
Music will tie
What's left of me what's left of me now

Terra's Lingering Will wandered the grand emptiness of the keyblade graveyard for a time too long for him to measure. What was most puzzling for him was how hours felt like days and a few minutes felt like only seconds. All he knew was he was alone on this godforsaken world and he couldn't remember how or why he was here. His hand was wrapped around a keyblade while his raging heart reminded him there was a reason he was supposed to use it; for what purpose was what he was unsure of.

He would methodically clomp one foot on the ground in front of the other in an attempt to find another person, creature, or even a plant that would suffice to prove he wasn't alone on this deserted wasteland. After a while, he just kept walking until he would drop to the ground and fall fast sleep against a rock in exhaustion. The years ticked away at a painstakingly slow rate and the only time this monotonous schedule altered was one day when three strangers arrived. Noticing the power surge caused him to stop in his tracks, his heart strumming in his chest at the prospect of not being alone. With a flick of his wrist, he disappeared in a gust of wind.

A small whirlwind formed in front of Sora, Donald, and Goofy in front of their arrival spot and when the dust disappeared, there was only an armored stranger staring at them through his tinted helm. For a moment, there was absolute silence until the armored man began to whisper.

"Aqua…Ven…Nova."

As he spoke those three names, Sora hesitantly summoned his keyblade by his side to prepare for the possibility at an attack. As soon as his keyblade was in his hand, Terra recoiled as if he was slapped and instantly felt the fog lift from his eyes.

"A keylade? I know you, but you are not the boy I chose. Who are you? You emit a power that is familiar to me."

Sora glanced behind him at his comrades with a confused look on his face.

"Xeha…nort? Xehanort! I will make you pay for killing Nova!"

Sora stiffened at the mention of Xehanort and felt the need to ask his own questions but it did no good since Terra instantly charged at the young boy with one mission on his mind. His purpose was known and his mind was clear; he needed to enact revenge on Xehanort for killing Nova. Sora tried to reason with him but to no avail and since Terra would just continuously attack the young keyblade wielder with such an incredible tenacity, it left no room for conversation. Donald and Goofy would coordinate to attack Terra while he was distracted, only to be knocked away by a surge attack that sent his body spiraling across the ground directly at Sora, foiling their attempts to save him from the assault. He was able to evade just in time but only to put him directly in the path of Terra's next attack.

"Sora, lookout!"

Donald and Goofy attempted to warn Sora about Terra's keyblade whip, but it came too late to be avoided. Terra's keyblade slashed the air around Sora and successfully picked him up and tossed his body across the desert. For a moment, Sora kneeled on the ground trying to calm his erratic breaths and heartbeat. He noticed Terra's body closing the gap between them and stood to his full height to resummons his keyblade.

Once Terra came close enough, he pointed his keyblade at Sora and waved his hand over the hilt, transforming it into a cannon. Sora's eyes grew wide and he jumped to evade the attack and glided around his enemy's body to attack him from behind. When Terra fell to his knees, Sora motioned to Donald and Goofy to come assist him and they ganged up and threw an onslaught of attacks his way, successfully bringing the lingering sentiment down.

"That's it, your power. That's what I felt within you. It felt just like Nova's," Terra said with resolve while slowly rising to his feet.

Striking his keyblade into the ground, Terra knelt behind it and in a gust of wind like the one he appeared in before; he disappeared from their sight to resume his life of wandering the battleground. Sora, Donald, and Goofy stared at the spot he disappeared from before they began to scratch their heads in bewilderment.

"Who's Nova?" they all asked rhetorically at the same time.

With a shrug, they boarded their gummy ship and flew into the sky onwards to the next world that needed saving, unaware of Terra's eyes watching them ascend. Keyblade in hand, he started walking around the desert again trying to count the minutes as they ticked his life away.

"Nova…"
