Once off they were bound for Castle Oblivion which Aqua revealed as the location where Ventus was. It was odd for Aqua to arrive at a world in anything less than an hour. Once there memories began flooding back into Sora's mind. "Wait!" Sora yelled. "This place belongs to the Organization! I was here when Namine erased my memories and turned my friends into cards." Mickey nodded. "I remember. We better careful." Upon entry they noticed that it seemed unusually empty. "Maybe they never game back after I defeated them last time." Sora said. "Or." Said a voice from behind. "We wanted to plan a sneak attack." Sora whirled around to see Xigbar. Braig's nobody.

Aqua summoned her Keyblade ready for a fight. "Braig! I though Terra finished you!" She yelled charging at the man. Sora wanted to ask how she knew Xigbar but refrained from doing so as to not interrupt. Xigbar aimed a shot but Aqua used her shield to send it straight back at his leg. Darkness seeped from the wound. He then retreated into a dark corridor to prevent further injury. Mickey looked at Aqua. "I'm afraid he is Braig no more. He has lost his heart to the darkness and has become something we call a nobody. Even his name is different. Call him Xigbar from now on." Aqua felt guilt knowing that she didn't have the will power to stop Terra from taking his heart from him.

They pressed on seeing various heartless that Mickey had to explain about. They didn't attack so the three let them be. Until finally they got to the secret door that led to Ventus's chamber. A chill could be felt as the door opened almost as if the main cause of the darkness in the worlds was in the room. Little did they know it was. Pressing forward they did not know what lay ahead. What had been sleeping for eons only to now be awakened by a heart entering its vessel? The room where Ventus slept was completely dark when they entered but when the lights came on they wished they had stayed off.

"I've been waiting. Sealed along with this broken blade for ages now. Thank you for freeing me. Now Xehanort's plan will finally be completed. Another Keyblade war!" Aqua knew the voice all too well. "Vanitas! How dare you trouble us again after the sacrifices we went through to lock you up!" Sora jumped back while looking at the person that stood in front of them. "He looks like... me!" Mickey readied his Keyblade hoping to finally finish the last of the unversed. Ventus was behind him still in a sleeping state.

Vanitas summoned the broken X-Blade he held onto while floating in the darkness that was Ventus's empty shell. "Now I will finish what my master started!" Before he could move a beam of light hit he causing him to vanish to god knows where. Ventus stood holding his Keyblade pointing at the exact spot the light had hit. "Ven!" Aqua yelled running to hug the boy. "Thank goodness your alright you had me so worried." Ventus winced. "Aqua you're squeezing me." She let go. "Sorry I'm just so happy to see you."
