As we observed what was around us (there's no turning back), we saw a very desolate purple sea and similarly colored platforms and Goofy said, "Gawrsh, is that all that's left of the worlds taken by the Heartless?"
"Those worlds will be restored if we beat Ansem and Stickee (I mentioned him to Sora as we discussed stuff with one another back after leaving Hollow Bastion for the first time), right?", Sora asked and Ilsa replied, "You bet".
"But, if we do beat them and all these worlds become restored and disconnected, what's gonna happen to this place? And to us?"
"Hmm. Now that you mentioned it, now I'm scared.", I said to him.
"This is a Heartless world, so maybe it'll just disappear. (We all gasped) But no worries. Even if this place goes poof, our hearts ain't goin' nowhere. I'm sure we'll find our pals again. Yup, I just know that we will."
"Yeah, you're right.", Sora said.
"Now I'm really worried.", Florina muttered.
As I saw Sora look at a lucky charm (made out of thalassa shells, and from Kairi as he told me when I asked him what that was), he muttered that he will return it to Kairi. We then strolled along, fighting Heartless and obtaining treasures as we went.
Eventually, we reached a set of 'terminals' and when we entered it, it turns out to be a fragment of a world we already visited and we had to redo every boss battle. (When it came to Atlantica and Halloween Town, we were instantly transformed into whatever we were there; i.e. in Atlantica, Sora's Co. are aquatic as ours were in scuba suits. When it came to Florina and Ilsa, who weren't with us in those worlds, they remained in their original forms except for Atlantica, where they wore scuba suits too) We also came in a certain world which I do NOT remember entering and Sora said this is a portion of the 100 Acre Wood.
When we left it, we entered an orange 'terminal' and as we explored, busted Heartless, and left afterward, we saw a hole and we jumped in. Just then, we were floating (and I did not even have Float equipped) and then a big, black devil (Chernabog) appeared and began to attack us.
We started by casting barriers to one another and good thing too since he suddenly made the volcano erupt and the lava spurts harmlessly fell away (the first seconds during the barrier's activation makes the targets invincible for a while, then it's down to half damage). Next, he started breathing fire, which we avoided by flying to his back (and attacked him while we were there). After we repeated this sequence a few times, he then flapped his devil wings and blew us away. Then he cast lasers toward us, which we had a hard time deflecting since Sora can't Guard while in the air and had to resort to hitting them back at Chernabog. As for me, I had a hard time swinging my shield around and only managed to land a few shots at the lasers (I was too busy to check on the others but they were still quite A-OK). When he was done, we flew to him with all we got and finally defeated him who disappeared in purple-white flames, leaving the volcano behind, which was now extinct.
We flew in and, after some more conflicts with the Heartless, we encountered a "Save Point" and a large door. After 'saving', the door opened and revealed… Destiny Islands.
"Is this… is this my island?", Sora asked.
"I doubt it. Probably a copy like the ones we've been through.", I remarked, referring to the 'terminals' we passed through previously.
We then walked to the "Secret Place" (Sora led us there), then we heard voices say, "This world has been connected." A small islet disappeared and Goofy gasped in surprise.
"Tied to the darkness… soon to be completely eclipsed." Half of the bridge disappeared.
"There is so very much to learn." The water turned purple.
"You understand so little. A meaningless effort." The place shook and cracks and holes appeared in the sky. As we wandered around, we suddenly saw Riku and Windelle in their Dark Forms.
As we approached them, they then said (but not with their voices, they belonged to the ones who said our journey was futile), "Take a look of this tiny place. To the heart seeking freedom and the heart seeking power this island is a prison surrounded by water. And so these boys sought to escape this prison. They sought a way to cross over into other worlds without a vessel's aid. And they opened their hearts to darkness." They then turned around and became Ansem and Stickee.
"Riku! Windelle!", we called out.
"Don't bother. Your voices can no longer reach then where they are. Their hearts belong again to darkness. All worlds begin in darkness, and all so end. The heart is no different. Darkness sprouts within it, grows, consumes it. Such is its nature. In the end, every heart returns to darkness whence it came. (He then appeared behind us.) You see, darkness is the heart's true essence."
"LIARS!", I said.
Sora continued for me, "The heart may be weak. And sometimes it may even give in. But I've learned that deep down, there's a light that never goes out."
They flew to the air and said as they crossed their arms, "So, you have come this far and still you understand nothing. Even light must fade, every heart return to darkness!" and Guardians appeared behind them (KH fans would know).
As Sora, Donald, and Goofy went for Ansem, (I had Gregorio and Ilsa for this battle.) the rest of us went for Stickee. As his Guardian shot projectiles at us, we deflected them as we approached him and I landed Combo Shots at him. Just then, the Guardian went for me, grabbed my shield, tossed it aside, and I ran my *** off from him since he was coming for me. With the aid of my shoes, I was able to stay ahead as I saw my companions, I also Stickee attacking them with a Dark Gun which Windelle had held with his GunDeLuna back at the team battle at Hollow Bastion. As I ran for Stickee, I then jumped over him and performed Taiyou at him and he was knocked down. When I checked out Sora and Co., he was done with Ansem.
The two evil ones then dismissed their Guardians, and opened a dark rift in the islands. We then ran (I retrieved my shield first, of course) and jumped in but when we landed, I realized only Sora, Florina and I got through (since she was not set as my ally due to the 6-fighter limit, she was automatically 'dragged in'). Just then, Darkside appeared and the three of us had to deal with him.
It was relatively easy and he was defeated. Just then, Ansem and Stickee appeared and engaged the three of us in battle. It was a long and hard battle but we eventually defeated them again. Just then, all of us, even our companions outside, were sucked into the Realm of Darkness (we were still able to see each other) and we found ourselves floating.
The voices of the evil duo then said, "Behold the endless abyss. Within it lies the heart of all worlds: Kingdom Hearts!" And we saw a silver door ahead. "Look as hard as you are able. You'll not find even the smallest glimmer of light. (On the contrary, I saw a glimmer of light just at the door.) From those dark depths are all hearts born. Even yours." Suddenly, we saw a giant Heartless battleship (the World of Chaos).
"Darkness conquers all worlds!" Just then, we were falling and as I saw our companions get sucked in a rainbow rift, Sora, Florina and I continued to fall (I noticed Florina was calm as if she had wings). Just then, I remembered to cast Float (which bacame permanent in this battle) on them and myself and we flew back to the vessel and dealt with the evil duo (Ansem only had his pants now and was wielding a 'Soul Eater' polearm).
I then cast barriers on all of us and kept to his left as we attacked him from afar (Sora used spells). We then came to their backs and attacked away. When lasers were launched from the World of Chaos, Sora and Florina ignored them and pressed on in the attack while I flew about deflecting them. Some time after fighting them, they fused themselves with World Of Chaos and a rainbow rift opened as we crossed it.
We ended up in a room with lots of Shadows, which we destroyed with ease. We also destroyed the floating thing above our heads and retrieved Ilsa, Gregorio, and Donald (All three add up to the 6-fighter limit). The six of us flew out and we then saw another rainbow rift just above the core of World of Chaos. As we flew for it, we had to deal with the Artillery in the way. Once that was taken care of, we flew to the rift and fought Darkballs that were inside. We also destroyed the floating thing above our heads and retrieved Yoris and Goofy (Ilsa and Gregorio are switched out in favor of our recovered allies).
We all then flew out and headed for the front of World of Chaos which we attacked. Eventually it was defeated and it exploded. We then flew to the core (which has lost its barrier) and barraged it with attacks. When it was destroyed, we saw Ansem and Stickee disengage from World of chaos and come for us.
-I'll leave the battle process to your imagination. XD-
After the battle, the two of them vanished for a while as World of Chaos began to explode. After the big bang, they returned to us, weakened (and Ansem was fully clothed again).
"It's hopeless.", they said. "The Keyblade alone can't seal the door to darkness."
They turned towards the door and called out, "Kingdom Hearts. Fill me with the power of darkness… (Black smoke spewed out of it as it was about to open) Supreme darkness…"
"You're wrong.", Sora said. "I know now, without a doubt. Kingdom Hearts… is light!"
And it was as it shined on the two who were stunned. Florina and I nodded to one another, then charged up our guns to perform Taiyou which pierced Ansem and Stickee as they vanished forever. After the ordeal, we landed and ran for the door and tried to close it, but to no avail. When Donald and Goofy looked across, the rest of us did too and saw Heartless everywhere.
As we kept on pushing, we suddenly saw Riku and Windelle across the door saying, "Don't give up! Come on, guys! Together, we can do it!" and they pulled on the door.
Just then, we saw Darksides appear and Ilsa valiantly chose and managed to cross the door, despite the thin opening and rush on them. Just then, the Darksides disappeared (and I was sure Ilsa wasn't the one who did it), and as we looked, we saw Mickey Mouse (whom Donald and Goofy addressed as "Your Majesty!") and a blonde boy in orange clothes (Whom Gregorio and Yoris called out by his name, which was Django).
They said, "Now Sora (Rael and Florina)! Let's close this door for good!"
As the four who called out their named told us to close it quick, Sora, Florina and I hesitated but King Mickey and Django then said, "Don't worry. There will always be a door to the light."
"Now! They're coming!", Windelle, Riku, and Ilsa shouted out.
The seven of us on the other side then pushed with all we got and just before it closed, Riku said, "Take care of her." and Ilsa said, "Don't worry about me! I will protect these guys!".
Sora, Florina, and I (we joined in since Ansem had said, "The Keyblade alone can't seal the door to darkness." so I told Florina to join in with Sora and I did the same, of course) jumped back and aimed at the door and shot at it (King Mickey, Django, and Windelle probably did the same).
Once the door disappeared, we saw Kairi up ahead and Sora ran for her (the rest of us laid behind and watched him go). Just then, the area around us became a countryside with a single road.
