The Mysterious Tower
Back in Yen Sid’s tower, Sora has yet to awaken. Yen Sid tells them that Sora’s heart is asleep. He reminds them of the task in the Mark of Mastery exam: unlock seven Sleeping Keyholes. In doing so, the worlds would awaken, and we’d gain the power to awaken a sleeping heart.
Riku unlocked the Sleeping Keyholes in Sora’s dreams. Therefore, he has the power to awaken Sora’s heart. He has to go into Sora’s sleep, but Sora’s heart is down in the darkest place possible. If Riku isn’t careful, he could meet Sora’s fate. Mickey offers to go instead, but fails. It is Riku’s task alone. Riku thanks him, anyways.
After some more chatting, Riku departs into Sora’s sleep.
On the dive down, tag 30 Soras. To do that, you simply must run into them. There are two good varieties - one in his Kingdom Hearts I/(Re:)Chain of Memories clothes, and one in his Kingdom Hearts II/3D (not dreaming) clothing. There is no time limit, so take as long as you need.
Don’t not worry too much about the dark ones that attack. You’d have to be pretty bad at this game to lose to them! When he lands, Riku is on a watery pool of darkness. Suddenly, a being rises behind him and attacks!
Boss: Armored Ventus Nightmare
After the clash, the armor shatters on the thing, revealing it to be Sora! Riku tries to pull him out of the whirlpool of darkness, and fails. The Kingdom Key beside him returns to light and Riku picks it up, and then seals a Keyhole. Hm.
Riku finds himself at the Destiny Islands, looking at that beautiful sunset. He turns around and meets Roxas, who asks what Riku is afraid of. Choose something (I chose “Losing something that’s important”).
Roxas then disappears and Riku finds Ventus on the beach, who asks what is the one thing you care about more than anything else. Choose (I picked “My close friends).
Then Ventus disappears and Riku walks onto the island, finding Sora there. He speaks with him and the Sora has transformed into Xion who asks what you wish. Choose something (I chose “To recover something important”).
Xion then disappears and Riku is on the beach again, and he sees a bottle in the water. He picks it up and opens it, finding a note inside. Before he can read it, DiZ - Ansem the Wise - comes to speak. He says that he digitized his research within Sora, to leave something behind of himself. (Remember, he died in Kingdom Hearts II.)
So, this is data, a clue, in the bottle. Ansem speaks of how malleable the heart truly is, moreso than the softest, hottest gold, and how Nobodies are little different. Sora was the only one able to become human without losing his Nobody. He may have the power to bring back those connected to him, those lost forever, and even Aqua, Terra, and Ventus.
Sora is willing to see the good before the bad, is uncorrupted, and can repair broken connections. He truly is remarkable.
After some chatting, Riku tells Ansem he needs to awaken Sora. It seems Sora is not here; when you defeat the Armored Ventus Nightmare, Sora was freed from his imprisonment. After the three questions, Sora was awakened, and Riku can seal one final Keyhole and return home.
And, well, we’ll leave it at that. Enjoy the ending!! And…
