Altar of Naught

Riku stood in Dark Mode, the Way to Dawn pointed at Xemnas, who simply stood on the other side of the tower. Sora, Donald, Goofy, and the King ran up the stairs, stopping as they saw this. "Riku!" Riku turned, keeping the Keyblade up.

"Sora! The moon!" Sora looked up, the moon directly ahead of them. It teemed with energy, the sky around it glowing.

"My Kingdom Hearts." Xemnas looked at it, then thrusted a hand up to it. "Now, reveal the door to me. Kingdom Hearts!" The moon shone with a brighter radiance, then seemed to collapse into itself. The pieces collected together, forming a door shape, which solidified into an ivory door, large stained glass windows adorning it. "Yes." Xemnas turned to Riku, then swung an energy blade at him, Riku jumping back. Xemnas charged over to the door, grabbing between the large double doors.

"No!" Riku yelled, shooting of an immense Dark Firaga. Xemnas backflipped over it, the attack hitting the doors.

"Yes." Xemnas looked back at Riku, a broad smile on his face. "Thank you, Riku." He turned to Kingdom Hearts, sweeping his hand through the air. "Kingdom Hearts, open for me! Reveal your darkness!" The doors creaked, then obeyed as the double doors slowly opened, darkness flowing out. It glided through the air, then flew into Xemnas. He was pulled upward with extreme force, the darkness pouring into his body. The other Organizers appearing.

"Whoa!" Demyx fell back, Xigbar helping him back up.

"Freaky, man." The Freeshooter and the others watched as the Superior was overcome by darkness, then gently let back down. His robe was now a mixture of black and white, his eyes a deep blood red.

"Now, for the main event. Xemnas walked into Kingdom Hearts. "Follow, if you dare." With that, he disappeared." Sora looked at the others nervously.

"Come on, you're not just going to let him get away with this, are you?" Luxord asked behind them.

"No, we won't." Sora replied, and walked up a glowing path to the door.
