Two seagulls were flying over the ocean towards a massive castle, surrounded by houses and windmills. They flew near buildings and dove back near the water again. In the water, there were fish swimming, causing ripples on the surface. The seagulls returned to the sky, soaring around where shimmering gondolas hung. These connected every massive castle in the area.

Long ago, after the fall of Daybreak Town, the surviving Dandelions joined together to continue their training on their sister world, Scala Ad Caelum. No one knows who made this place, or how long it's been here. However, this was originally a safe haven for Keyblade wielders before the war. Now, only a few hundred are allowed here. Among them, were two students. They were the younger versions of Eraqus and Xehanort. The two were playing a game of chess and having a conversation.

Xehanort: Have you heard of the ancient Keyblade War?

Eraqus: Huh? Of course I have.

Xehanort: Long ago, (knocked out his friend's white pawn) Keyblade wielders waged a war over the ownership of light.

Eraqus: Yeah, (made his move) the Master's favorite story.

Xehanort: I wonder what they planned on doing with Kingdom Hearts after... making it appear.

Eraqus: Who knows? I don't get why anyone would initiate a war.

Xehanort: (collecting more white pieces) So... you know the "Lost Masters"?

Eraqus: Who?

Xehanort: They're the ones who started the Keyblade War.

Eraqus: Never heard of 'em. (moved his white piece he had and took another black piece) Where'd you hear about that?

Xehanort: Or... (another white piece) they're the ones for whom the war started.

Eraqus: I'm not following you. (took another white piece)

Xehanort: You can drop the facade.

Eraqus: Facade?

Xehanort: "On that land shall darkness prevail and light expire." A prospective Keyblade Master should know this.

Eraqus: If you say so.

Xehanort: (looks up at the Keyblade on the wall) The Gazing Eye sees the fate of the World. The future—it's already been written.

Eraqus: Really? I'm not so sure about that. Besides, who's to say I can't change it? And maybe light will prevail. (grabbed his white piece and took down another black piece) 

Xehanort: (chuckles) Pretty confident. But things aren't in your favor. (moved his black piece and took another white piece) 

Eraqus: Perhaps. But unlike darkness, there is more to light than meets the eye. 

Eraqus another black piece. He then looked up towards his friend with a new fire beginning in him.

Eraqus: You might be surprised.

Xehanort could tell something was brewing, meeting his friend's eyes over the chessboard.

Xehanort: Oh, I hope so.

(present time) 

Narrator: At long last, the time had come. The planets were edging into perfect alignment... and the plan Hades devised eighteen years ago was about to reach fruition. The Fates had predicted this very future-the day he would seize control of Olympus and rule over all the cosmos. Hades' previous attempts-using Terra, Cloud, and Auron to advance his plans for conquest had failed. The hour was not yet right. But now, the planets were aligned and nothing could possibly go wrong. A wave of darkness lanced down from their celestial rank, and one by one, Hades freed the Titans from their prison-some of them the same monstrosities that Sora and his friends had already fought and bested before. With both the Titans and his longing for vengeance against Zeus reinvigorated, Hades began his attack on Olympus.

(Olympus Coliseum) 

The new team arrived in an area with a giant mountain. They were to meet up with the trio's friend, Hercules, but they arrived at a different part of the world than usual.

Sora: Huh? Uhh... (looks at the others) No fanfare? (mimics a trumpet)

Donald: (listens but no music) Un-uh...

Trish: Are we even in the Coliseum?

Modeus: Doesn't look like it.

Goofy: (looks around) Nope, looks like we missed the Coliseum.

Happy: So where are we? 

Donald: (glares at Sora) Sora, you opened the gate!

Wendy: Come down, Donald. 

Sora: (chuckles) Guess I was a little off again. Sorry! We'll find him. But we need to go!

Erza: He's right. 

Ur: Where do we start? 

Sora then began to walk towards the mountain.

Lady: Wait... we're gonna climb up that mountain? 

Sora: (turns around) Yeah. Up is the usual direction.

Natsu: I like the way you think Sora. Let's go, Happy! (run towards the cliffs)

Happy: (follows Natsu) Aye sir!

Drake: Works for me.

Goofy: Well, never hurts to have your head in the clouds.

Sora: Exactly!

The group follows while Donald and Lucy groan a little bit together. 

Kat: Hey, we're leaving!

Donald and Lucy panicked and ran after the group. As they exit the cave, the group was ambushed by Shadows, Soldiers, Large Bodies, Air Solders, and Earth Core Heartless.

Gray: I guess this is the welcoming committee.

Trish: Looks like it. 

Lucy: Here we go! (took one of her golden keys) Star Dress: Virgo Mode!

Lucy's regular clothes disappeared and her Virgo clothes appeared. Erza requipped into her Morning Star armor. Trish equips Sparda, Lady brings out her bazooka, Modeus summons his twin swords from the ground, and Kat pulls out Defiance. 

Natsu: Fire Dragon Roar!

Natsu release a large quantity of flames from his mouth at the Soldiers.

Gray: Ice-Make: Lance!

Gray creates ice lances at the Air Soldiers. 

Trish's body surged with lightning as she leapt at an Earth Core at lightning-fast speed and swung the Sparda-sword at the Heartless, cutting it in half. 

Lady fires her bazooka, taking out a few Heartless. A few Earth Cores borrow underneath the ground and formed into a tower made of sand.

Modeus: Demon Sword: Residual Moon!

Modeus slid under the Earth Core Tower as a white crescent-moon-shaped energy formed on the Earth Core itself before it exploded further and dissipated. 

Lucy dug and disappeared into the ground and reappear underneath the Shadows that blended with the ground.

Erza: Morning Star: Photon Slicer!

Erza fired a powerful energy blast from her dual swords at the Large Bodies. Laxus unleashes his lightning at two Large Bodies which electrocuted them. 

Drake: Agni! Rudra!

Drake pulled out his two short swords and sent a massive gust of fire and wind straight at five Solders and three Earth Cores. 

Ur: Ice-Make: Geyser!

Ur creates a tower of ice spikes that stabbed through a small group of Shadows and Soldiers. 

Wendy: Sky Dragon Roar!

Juvia: Water Nebula!

Wendy had unleashed her breath attack at the same time Juvia shot a cyclone of water. Wendy and Juvia used a Unison Raid of wind and water on the Air Soldiers.

Gajeel: Iron Dragon Lance: Demon Logs!

Gajeel's left arm turned into a metallic spear and begun to rapidly shoot spikes of green energy like a machine gun straight through the Shadows. 

Kat, Panther Lily, Goofy, Donald, and Sora finished the last group of Large Bodies with their weapons.

Gajeel: That was a good warm-up!

Panther Lily: So that's how the Heartless function.

Kat: And there's gonna be plenty more where that came from. 

They then walked to a mountain wall.

Lucy: How are we going to get up?

Sora: We run up it.

Lady: (looks at Sora like he grew a second head) Seriously?

Sora: C'mon, let's try it!

Sora backed up, ran straight the wall, and ran up to the top.

Sora: See? Now you try it. 

The group then repeated his idea, made it to the top, and kept on going until they reach a cliff.

Goofy: I think we might be goin' in circles.

Trish: You mean you don't know where we're going? 

Donald: Sora...

Sora: Did I make a turn at the wrong rock?

Gray: Great, now we're lost.

Juvia: (looks at Sora) Can't you do something?

Sora: (calls out) Hey, Hercules! WHERE ARE YOU?!

They only received silence. Suddenly, a puff of black smoke floated down to them. When it lands, it was revealed to the Lord of the Underworld himself, Hades.

Hades: All right. I know I dotted my I's, crossed my T's, zeroed the hero. So what gives? Who could possibly be trying to give me a migraine by yodeling that yutz's name? (notices the group) 

Wendy: Who's that? 

Sora: (sighs) Really? Hades?

Hades: (sighs) Oh, it's just you. Oy vey. (sees Drake) Though, you're new. What's your name, pal?

Drake: Drake. Though, don't forget them. Even for a hot head like you, that's cold.

Hades: Don't forget...I can always turn up the heat!

Kat: Wait a minute. If this Hades guy is here, then where's Hercules? 

Hades: What is everyone's infatuation with that dolt?! (turns red)

Natsu: (laughs) This guy hilarious! He has fire coming out of his hair!

Lucy: (scared) That's not normal, Natsu!

Hades: And who are this guys?!

Natsu: (starts eating Hades' hair) Hey, your fire hair taste delicious!

Hades: Get off of me! 

Lucy grabbed Natsu and pulled him away from Hades who still looked furious.

Hades: (goes back to blue) You know what? Never mind, never mind. I'm cool, I'm good. Because, wonderboy'll be outta my hair soon enough.

Sora: (summons Keyblade) So you're up to no good again! 

Donald and Goofy summoned their weapons while the Fairy Tail wizards got into fighting positions.

Goofy: Of course he is.

Donald: You bet!

Erza: Facing the members of Fairy Tail is a grave mistake.

Natsu: This'll be fun!

Lady: I've only met him for a few minutes, and I can already tell he's a prick.

Hades: (turns around to face them) whoa, easy—what is this, Sparta? Kind of on a schedule. Don't have time to toss around the old fire and brimstone. (turns around again) The whole cosmos is basically waiting for me to, you know, conquer it! (walks away)

Sora: (everyone dismisses weapons) Poor Hades. He thinks he can actually pull it off this time.

Modeus: Don't get too cocky. You never know what they have up their sleeve.

Hades: Where are my Titans?! SHOW ME YOUR POWER!!!

The clouds in the sky began to darken. 

Ur: The sky is getting dark?  

Kat: It was broad daylight a few minutes ago.

Just then a powerful earthquake occurs.

Lady: Now an earthquake?!

Then an icy cold mist appears as well as a powerful gust of wind. A volcano at the top of the mountain began to erupt, with lava beginning to flow down the mountain.

Drake: What the hell's goin' on?!

Modeus: This is a sudden weather change for us! 

Trish: This is getting way outta hand! 

Hades: Ahh! Love the breeze.

The gust of wind was so strong that it sent the group flying off the mountain edge.

Hades: (stroke his chin) Ahh. That sent 'em sailing. (frowns for a moment) Sailing right to where I left... Eh, no biggie. (looks back at his Titans) Nice work, boys! So, back to the whole cosmic coup thing?

Satisfied, Hades sends the Titans back and he was about to take his leave, when he hears a corridor of darkness open.

Hades: Ugh. Really? Are you kidding me? Geez Louise. Seriously, when it rains, it pours. (turns around) Okay, who's the new pest?

Pete: (enters with Maleficent) Hey, now, that ain't no way to say hello, 'specially to your old friends.

Hades: Oh, perfect. Now I gotta put up with you two. Funny, I don't remember you doing me any memorable favors. So, you can keep your Heartless this time. I'm going back to my original plan. All right? So...toddle-oo! (points to his right) Exit's thataway. Hey, it was great seein'ya! (sings a bit) Happy traaails!

Maleficent: We are not here for you. I have my own business to attend to. All I need to know is if there is a distinctive...black box...somewhere in this world?

Hades: Black box, huh? Hmm... black box, black box, black box... (thinks of something) Wait. Don't tell me... you're after the one Zeus hid on earth?

Maleficent: Possibly. If I were, where might it be?

Chapter 37 ended.
