In the middle of a dark forest, two figures walked into view. The taller one was a man clad in a cape and armor except for his head. He was muscular with spiky brown hair and blue eyes. Beside him was a 4-year old boy. He, too, had spiky brown hair and blue eyes. Both of them had sad, solemn faces.

They arrived at their destination- a cemetary. In the middle of all the graves was a circle of stones, and in the middle, a crystal. Inside it was the body of a woman. She had light blue hair and eyes. She, too, wore armor and a cloak.

"Say hi to Mommy, Sora," said the man. The boy only waved. The man sighed. Why... why did they have to kill her? She wasn't the one with an unknown power locked away in her... the boy was. But he wouldn't make them swap places, even for the world. Sora was his son, and he was Aqua's, too. She wanted it this way.

Sora had shown signs of being able to wield the power of the Keyblade as soon as he was born. However, when he was two, it was revealed by Master Eraqus- Terra's old master- that Sora had an unknown power within his heart. At that moment, the Purgatory Knights had attacked out of nowhere and struck the Master down.

The Purgatory Knights were the reason for all this madness. They believed that any other Keyblade wielders should be eliminated, that only they had truly pure hearts. They were the reason that they were on the run, that Aqua was dead.

-1 year earlier-

Terra and Aqua stood in front of the house. Ten purgatory knights surrounded them.

"Tell us what you want!" Terra shouted.

"You know exactly what I want." A tall man with silver hair walked through the knights and stood before Aqua and Terra. He wore a long cape over his pitch-black armor. "I want Sora."

"Why?"

"Don't play dumb with me. I know what Eraqus told you. Surrender him to me, and I may spare you."

"We would rather die than let you have him!" Aqua said. She summoned her Keyblade. Terra did the same.

The man smirked. "Have it your way." He summoned a dark lance and launched it at Aqua. Terra hit it away, then turned and swung at the man. He dodged, but Terra pressed the attack. As Terra occupied the man, Aqua did a high flip and landed behind him. She prepared her weapon for a stab...

At that moment, the man, unleashed a powerful blast of dark energy that knocked Terra back. He then turned around, dodging Aqua's stab, summoned a dark blade...

And thrust it into Aqua's stomach.

"Nooooo!" Terra screamed, rushing towards Aqua. He caught her as she fell to the ground.

"Consider this a warning," said the man. "We're done here." He raised his hand, and the Purgatory Knights began walking away. Following them, he looked back at Terra, smirking.

Terra looked at Aqua. "No... Aqua, you... you can't die. You can't! You're my wife, one of the few people I care about."

At that moment, a little face poked out from behind the doorway. "Are they gone?"

"Yes, Sora. They're... gone..." Aqua said, her strength waning.

"What happened to Mom?"

"Come here... Sora..."

Sora came to her side. "Is she gonna be okay?"

"No..." Terra admitted. "She's not."

"Sora," said Aqua, "I need you to remember something." Sora nodded. "Remember... I'll always with you... in here." She pointed to his heart.

"Mom... Momma, don't go! Please, Momm... please..." Sora was in tears, grasping Aqua's hand.

Aqua reached up with her other and touched Terra's cheek. "I... love you... both. Never forget... that's the truth." Her hand fell from her husband's face.

"No! Aqua..." Terra grabbed her hand. "Please... Aqua..."

But it was too late. Aqua was gone.

"No... No!" Terra sobbed. Sora cried, too. They had both lost something important that day. They never forgot.

-Present Day-

Terra and Sora stood in front of Aqua's grave.

"Sora, we need to leave."

"Okay." They turned and walked away from the graveyard. As they were walking, however, Sora stopped walking.

"Daddy, do you think Mommy meant it?"

"Hmm?"

"When she said that she would always be with me. In here." He pointed to his heart.

"When Mommy said things, she meant them. She will always be with us."

Little did he know, that meant more than he thought.
