Third Person's POV

"I have identified the scent. It is Riku" Zexion said "Riku, you say? Has he emerged from the realm of darkness?" Vexen asks "His existence-it was once doubled in the darkness" Zexion said "Fascinating... That's why you mistook him for the Superior" Vexen said "The dark power given to Riku facilitated his escape from its realm" He said "What I want to know is why he appeared here in Castle Oblivion" Zexion said "That's really quite simple. His existence resonates with that of another heroes" Vexen said "Sora and....Brody are in the castle?" Zexion asks, he had vague memories of his and Vexen's encounter with Brody in Radiant Garden in the old days "They arrived earlier" Vexen said "Marluxia is already using Naminé's unique power to meddle with Sora's heart" He said "Without even bothering to consult us" Zexion said "It seems he desperately wants the Keyblade wielder for himself-what a foolish plan, indeed" Vexen said "Sora's is not such an interesting existence. The entities that hold true value-" He said "is Brody who I theorize holds deep connections with this castle. And Riku, the hero of darkness" He said smirking.

*Meanwhile*

Riku's POV

I went upstairs to the 10 floor of the basements and walked to the door using the monstro card to unlock it and went inside.

After I went through the area and took out the heartless I left the room back to castle oblivion and then someone appeared "I take it you're Riku" The man said "Are you with Ansem?" I asked "You are half correct" The man said and introduced himself as Vexen "Let us say that he is not the Ansem with which you are familiar" Vexen said "He is Ansem and he is not Ansem. Perhaps a 'Nobody' best conveys the idea" He said "Riddles were never my thing. Try again" I said  "He belongs to neither the light nor the dark but walks the twilight between" Vexen said and I gasp making Vexen chuckle "Catching on now?" Vexen asks "Oh yes, you also stand in between the light and the darkness" He said "It appears we have much in common" He said "Maybe..." I said "Like you said, there really is darkness left inside of me" I said "But so what? Darkness is my enemy!" I said summoning my keyblade "And so are you for reeking of that awful smell!" I said "Oh ho! So it's a fight you want" Vexen said "Very good-I shall take you on!" He said and I got ready to fight.

*After the fight*

I leaped and charged towards Vexen who blocked my hit with his shield and laughs "I find, coursing through you, there is a darkness of formidable power growing!" Vexen said "Well worth the trouble of aggravating you" He said "All this excitement has provided me with invaluable data" He said "What?!" I asked and he pushed me back using his shield "Many thanks, Riku!" Vexen said disappearing a dark portal "Tch. It was a trick all along" I said and I start to walk to the next floor wondering what is he plotting.
