Chapter 3: Destruction of Both Worlds

It's nighttime in Destiny Islands and Sora is in his room, lying on his bed, and looks up to see his wooden toy boat with two toy passengers.

"I just can't wait once we set sail. It'll be great." Sora remembered what Kairi said from the sunset.

Just then, Sora hears a loud roar and turns to his window to see the skies completely dark with lightning.

"A storm…? Oh, no! The raft!" Sora said, getting up.

"Sora, dinner's ready! Come on down!" Sora's mother called, but no response. "Sora?" Sora's mother asked, going into his room, only to find the room empty and the window is open.

Meanwhile, Arthur is still in his room and lying on his bed while looking up at the ceiling and remembering Merlin's advice.

"I wonder what my path will be like. If Merlin said it's up to me, what would be the path I'd choose? What do I want with my heart?" Arthur asked to himself.

Just then, Arthur hears a roar from outside, so he looks out his window to find the sky completely dark with lightning flashing and thunder roaring.

"A storm? Now? Well, it should pass, I hope." Arthur said.

"Don't even think that, Arthur." A voice said, making Arthur turn to see same armored masked figure leaning against the wall.

"Wh-Who're you? What's going on?" Arthur asked.

"Go out and see for yourself. Though I wouldn't promise that you and that old geezer would be safe right now." The armored masked figure said.

"I don't know what you're talking about." Arthur said, looking out his window again, but notices the figure is already gone. "I want to hope it's just a storm, but I have a bad feeling." Arthur said, but just then, someone appears and it's Merlin and Archimedes. "Merlin! Something feels wrong." Arthur said.

"Yes, lad. This is no ordinary storm. We need to get of here before it's too late." Merlin said.

"But what about Sir Ector and Kay?" Arthur asked.

"I'm afraid there's no time, lad. Come on." Merlin said, as he, Arthur, and Archimedes disappear from Arthur's room.

Meanwhile in Destiny Islands, Sora arrives at the island and sees a giant orb in the sky.

"What's that?" Sora asked and then finds two more boats. "Riku's boat and Kairi's." Sora said, but then, something emerges from the ground and they are black creatures with yellow eyes. "The ones from my dream!" Sora said shocked.

Sora tries to attack with his wooden sword, but he's not hurting them and one of the shadows attack, only for Sora to escape. Sora makes his way through the island and then heads for Paopu Island, where he finds Riku.

"Where's Kairi? I thought she was with you!" Sora said.

"The door…has opened." Riku said.

"What?" Sora asked.

"The door's opened, Sora. Now we can go to the outside world." Riku said.

"What're you talking about? We gotta find Kairi." Sora said.

"Kairi's coming with us!" Riku said abruptly, making Sora aback. "Once we step through, we may never come back. We may never see our parents again. There's no going back, but this is our only chance. We can't let fear stop us. I'm not afraid of the darkness!" Riku said, offering his hand.

"Riku…" Sora stops talking, as darkness appears under Riku.

Darkness starts wrapping around Riku, as darkness also wraps around Sora, despite his struggle, but he tries to reach for Riku, but both boys are in darkness. Just then, a bright light appears in the darkness, freeing Sora from the darkness and in his right hand is a key-shaped sword with a silver blade and teeth looking like a crown, gold hilt, dark grey handle, blue circle around the silver blade, and a silver keychain with a mouse head at the end.

"Keyblade… Keyblade…" A voice said.

Merlin and Arthur are at a different castle and are at a churchyard.

"Here we are, lad. Now we need to find the sword and put a stop to this." Merlin said.

"Wait, what sword? What's going on?" Arthur asked, looking up at a giant orb in the dark sky.

"What matters, Arthur, is to hurry and find that sword quickly and get out of here." Merlin said.

"Oh, and miss all the fun?" A voice asked and they see Morgan on the stained-glass window.

"Morgan? Did you…cause this?" Arthur asked.

"Well, not really. This world was chosen. Oh, Merlin, how nice to see you again, you useless old piece of garbage!" Morgan said, jumping off the stained-glass window.

"I should have known it was you, Morgan! I warned you about the path you'd take!" Merlin said.

"What do you mean by choosing this world? Choose it for what?" Arthur asked.

"Oh, it's cute that Artie is so ignorant. I'll explain; the door is finally opened. This world is nearing its end and not even Merlin will do anything about it." Morgan said.

"What?" Arthur asked.

"So that's what she meant about finding a door to this world." Archimedes said.

"This shall NOT stand, Morgan!" Merlin yelled, pointing his wand.

"Hahaha! You really think you can stop this, old man? You may have been my former mentor, BUT I'm much more powerful than you think!" Morgan said.

"Wait, is this true, Merlin?" Arthur asked.

"I will NOT allow you to cause harm to anyone, especially Arthur!" Merlin said.

"Hahahaha! You really think you can still protect this little gnat? He has nothing and IS nothing! He's not worth protecting!" Morgan said.

"You would do well to stand down!" Merlin said.

"Oh, but what about him?" Morgan asked.

"What?" Arthur asked, but just then, something grabs him and it's a giant black griffon.

"Arthur!" Merlin said.

"I hope I'm not late for the party." A voice and arriving is the same man in red armor.

"Nope. You're just in time, Ruber." Morgan said.

"Very good and it seems like Kay and Silver Knight have done their job." Ruber said.

"Yep, so can we kill them?" Morgan asked.

"Yes, but not young Arthur. I have special plans for him." Ruber said and turns to Merlin. "Ah, you must be Merlin, the most powerful wizard." Ruber said.

"And you must be Morgan's new mentor?" Merlin asked.

"You could say that. You see, Morgan and I have a common goal in mind; gaining power! I can't have you and this brat get in my way!" Ruber said, summoning what looks like a black flaming sword with a crimson hilt. "So, you die here and we'll be relieving you of your babysitting." Ruber said, charging at Merlin to attack.

Merlin casts a barrier to block off Ruber's sword attack, only for Ruber to continue attacking with his sword to break down the magic barrier, but Merlin unleashes a magic blast to send Ruber away, only for Ruber to use his sword to skid to stop. Before Merlin can attack, Morgan conjures a purple lightning spell to strike at the wizard, who teleports away and then reappears to Morgan and unleashes another magic blast, only for Morgan to conjure her own magic blast and the two blasts clash with each other.

"You disappoint me, Morgan! You were such a good student!" Merlin said.

"Yeah, I WAS! Then, Ruber and two more people actually recognize my true talents in magic! I created my own path!" Morgan said, as Ruber sneaks behind Merlin to attack.

"Merlin!" Arthur cried.

Before Ruber can attack, someone blocks the sword attack and it's a white robed figure and carrying a sword with a pure white blade while the hilt is blue and at the end of the sword is a chain with an angel wing.

"What are you doing, you wretched worm?!" Ruber demanded, but the white robed figure delivers an impaling strike at Ruber, who backs off.

The white robed figure goes for the griffon, who tries to attack, only for the robed figure to deliver a strike with the sword and then takes out a silver bow and fires arrows, making the griffon screech in pain and dropping Arthur.

"Are you okay, Arthur?" Archimedes asked.

"I think so…" Arthur said.

"You useless oversized bird! Grab the boy!" Ruber commanded, as the griffon tries to grab Arthur.

The white robed figure strikes the griffon again with the rapier and grabs Arthur's arm and they start running.

"Wait! Merlin!" Arthur cried, as they run.

"Go, Arthur! Be safe." Merlin said, as he continues battling Morgan and Ruber.

"Oh, no! You're NOT getting away! Valken! Sick them!" Morgan ordered, as the black and dark grey wolf chases after them.

The white cloaked figure takes Arthur into the next area of the churchyard, where they find what looks like a sword with a white blade and gold hilt on a stone pedestal.

"A sword?" Arthur asked and the white cloaked figure gestures for Arthur to go for the sword.

Just then, Archimedes sees something coming.

"Um, we're in trouble!" Archimedes said, as the wolf arrives.

"That wolf from before!" Arthur said.

"No escape now, you little fools! Now hold still while I have my dinner!" Valken said, as he lunges to attack.

The white cloaked figure fires more arrows and then strikes at Valken with the sword to keep the wolf back and gestures Arthur to go for the sword.

"You want me to get that sword? But…" Arthur stops talking, as Valken attacks the cloaked figure with his claws.

"I think you'd better do it and quick!" Archimedes said.

"I don't know if I can even pull it…" Arthur said, but just then, more shadows appear, as well as ghouls and they leap to attack Arthur.

"Too late, brat!" A voice said, as the masked armored figure appears. "With you out of my way, I'll be getting my hands on that sword and you won't stop me." The armored masked figure said, going for the sword, but then, Archimedes flies to stop him.

"Oh, no you don't!" Archimedes said, attacking the masked figure.

"Back off, you annoying bird!" The armored masked figure yelled, swatting the owl away.

"Arthur! Hurry up and get that sword and help that stranger!" Archimedes said, flying to attack the masked figure, who manages to grab the owl.

Arthur tries to crawl, as the shadows and ghouls are still on him, but the cloaked figure destroys the shadows and ghouls while still fighting Valken, who lunges to attack, only for the cloaked figure to keep attacking with the rapier and firing arrows, allowing Arthur to go for the sword. More shadows and ghouls appear and try to leap at Arthur and attack him, but Arthur crawls for the pedestal, only for the masked figure to try and stop Arthur, but Archmiedes keeps trying to attack. Arthur manages to reach the sword, as the shadows and ghouls keep leaping on him, preventing him from grabbing the sword, but Arthur's right hand reaches for the sword's hilt and starts to lift it.

"No!" The masked figure yelled.

Arthur keeps trying to lift the sword from the pedestal and after lifting the sword, a bright light shines, destroying the shadows and ghouls.

"The sword!" Valken yelled.

"He got it?" Archimedes asked.

"Excalibur… Excalibur…" A voice said.

Meanwhile, Sora makes his way through the island while fighting off the shadow creatures with the key sword, as it can destroy them. Sora later finds a door where the cave is and opens it, taking him into the cave and Sora rushes through the cave to find Kairi with the door.

"Kairi!" Sora called, making Kairi turn to see Sora, but has a sad look.

"So..ra…" Kairi said in a monotone voice.

The door opens, causing gusts of wind to blow Kairi to Sora, who tries to grab her, but she disappears and the gust sends Sora out of the cave. Sora lands on the beach, but looks around to see there's nothing left in the island and Sora's in the dark skies, reaching for the orb.

"This is…" Sora stops talking, as he turns to see a giant shadow creature with yellow eyes, small wings, black tendrils on its teeth, giant claws, and an open heart hole on its chest. "You again? Better deal with this!" Sora said, taking out his key weapon.

(Boss Theme: Destiny's Force)

The dark creature known as Darkside places its head on the ground while unleashing a shockwave and later, Darkside pulls out a giant red orb from the ground and then makes it explode, raining down small spiked orbs. Sora dodges the raining spiked orbs and starts attacking Darkside's right arm with the key sword, only for Darkside to unleash dark energy around its hand and thrusts its hand on the ground, creating a pool of darkness. Many shadows emerge from the pool of darkness and they attack Sora, who easily defeats them and keeps attacking Darkside's arm with his key sword, but Darkside uses its heart-shaped hole to unleash dark projectiles at Sora. The spiky-haired boy dodges the projectiles and keeps attacking the arms with his key sword and manages to climb and delivers the final blow on Darkside's head, making it hold its head in pain.

Darkside ascends up for the orb while Sora tries to hang onto a piece of wood to struggle away from the orb, but despite his effort, Sora's grip gets weak, as the orb's suction gets stronger. Sora lets go of the wood and ascends for the orb while taking one more look at his island home.

Meanwhile, Valken keeps attacking the cloaked figure, who strikes back with the sword and Arthur goes to help with his new sword in hand.

"Hang on! Let me help!" Arthur said, but the masked figure delivers swing kick at the blond, knocking him to the ground.

"Hand over that sword or I'll kill you where you're lying!" The armored masked figure said.

"No." Arthur said.

"Fine!" The armored masked figure said, as he goes to attack.

Just then, a magic blast makes both the masked figure and Valken back off.

"Get away from the boy!" Merlin yelled.

"Merlin!" Arthur said.

"You… You have the sword! Excellent!" Merlin said, but the shaking gets worse, as the churchyard gets into bad shape. "We're too late!" Merlin said.

"You don't stand a chance now, old man!" The masked figure said.

"We'll enjoy your death, as this world dies!" Valken said, as the masked figure creates a dark portal and he and Valken escape, but the cloaked figure goes after them before the dark portal disappears.

"Wait!" Arthur called, but the cloaked figure is gone.

More ghouls and more shadows appear and surround Arthur, Merlin, and Archimedes.

"What now?" Archimedes asked and Merlin creates a portal.

"Arthur! Go to that portal! Hurry! I'll hold them off for as long as I can!" Merlin said.

"But…" Arthur was cut off, as Archimedes drags Arthur for the portal.

"There's no time! You have to go!" Archimedes said.

"Listen to me, lad! While this world may perish, you'll still have a chance to make things right. I believe in you!" Merlin said.

"No! I don't want to leave you! Merlin!" Arthur said, but Merlin uses his magic to send Arthur to the portal. "MERLIN!" Arthur cried, as the portal closes, as Merlin fights the shadows and ghouls.
