Along with the written story I’m going to post here, I recorded all the cutscenes of the game from each caracter and put them together in the order I thought fit best according to the timeline. It will obviously be posted in several parts because the all the cutscenes together is like 5-6 hours worth of footage. I’ll post the videos that are relevent with what I write here so you can watch them if you need more details (or if you just want to skip reading what I wrote and just watch it happen haha)
Ventus then travels to the Castle of Dreams where he finds himself in a tiny size. He meets Cinderella and her mouse, Jaq. Jaq fills Ventus in his plan to make a dress for Cinderella so she can go to the ball. Ventus helps him find the few last materials needed, finding himself battling a giant cat int he process. After finishing the dress, Ventus and Jaq talk about dreams before Ventus leaves. Terra then arrives to find the aftermath of Ventus’ efforts. He finds Cinderella crying in a torn dress. He witnesses the Fairy Godmother transformin Cinderella. Seeing that Cinderella has a pure heart, he decides to escort her to the ball where he learns that a boy in a mask seems to be controlling the Unversed. Before leaving, Terra bumps into Aqua and tells her he has found out Master Xehanort is looking for pure hearts. After Terra leaves, Aqua walks in the ballroom right as Lady Tremaine and her daughters leave. She senses something very wrong coming from those ladies and decides to investigate. When she arrives in front of Lady Tremaine’s house, Aqua senses darkness inside and wishes to fight it off, but she is stopped by the Fairy Godmother. She tells Aqua it is dangerous to fight darkness with light since they go hand in hand; you can’t have one without the other. The Fairy Godmother then tells Aqua that a friend of Cinderella is trying to keep her light from fainting, but he needs help. Aqua accepts to be shrunk so she can go inside and help Jaq. She finds out Cinderalla has been locked inside her room to prevent her from trying on the glass slipper. Aqua helps Jaq in finding the key to Cinderella’s door. She transforms back in her normal size, just in time to distract the Grand Duke while Jaq unlocks Cinderella’s door. Cinderella manages to come down and prove she’s the one the Prince is looking for.
Aqua then finds herself in the Dwarf Woodlands. She comes across the seven dwarves’ home where they’re surrounding a casket with a girl inside. Aqua learns how Snow White was tricked into taking a bite of a poisonous apple and now lies inside the casket. Aqua tells the dwarves she’ll go to the castle to try and fix this. On the way, she meets a Prince that’s looking for Snow White and she tells him where he can find her. In the Queen’s chamber, Aqua doesn’t find the Queen but is instead absorbed by the mirror. After fighting the mirror, Aqua returns to the dwarves’ home where she witnesses the Prince kissing Snow White and then Show White waking up.
Meanwhile, Ventus traveled to the Enchanted Dominion. There, he learns from the fairies that Aurora is in an eternal slumber caused by Maleficent and that her heart had been stolen. When Ventus finds Maleficent, she tells him it was Terra that took Aurora’s heart. Ventus doesn’t believe Maleficent and battles with her. After defeating Maleficent, Aqua shows up while Ventus and Maleficent are arguing about Terra. Aqua reassures Ven that Terra would never steal Aurora’s heart and then she insists Ven returns home with her. Ven refuses to go back home, still wanting to find Terra. While Ventus leaves the Enchanted Dominion, Aqua stays to confront Maleficent. Maleficent tells Aqua she could use her help to collect the pure hearts, but Aqua refuses and is sent in the dungeon. There, she meets Prince Philip and learns he got captured while trying to free Aurora from her deep slumber. Together, they make their way out of the castle and fight Maleficent in her dragon form before arriving at the castle where Prince Philip kisses Aurora and she wakes. Aqua then leaves the castles and sees Maleficent again. She tries to convince Maleficent that she will never be able to overcome a heart filled with light. Maleficent then tells Aqua she must not forget that as long as there is light there will be darkness.
Terra decides to visit Master Yen Sid in the Mysterious Tower since he’s the one that had given the news to Master Eraqus about the Unversed. After landing, he sees Micky rushing off into space. Master Yen Sid informs Terra that Xehanort and the Unversed might be connected and that he should seek him out to get answers. After getting council from Master Yen Sid, Terra hears Master Xehanort’s voice calling him to the Badlands. Master Xehanort tells Terra about Vanitas, but he says he didn’t mean to seperate Ventus’ light and dark side and that he had tried to protect the pure hearts against Vanitas ever since. He asks for Terra’s help. After Terra leaves the Badlands, Ventus finds himself there. In the Badlands, he is faced with the masked boy again and this time they fight. Before being defeated by the masked boy, Mickey arrives and saves Ven. After the masked boy leaves, Ven learns that Mickey is also a Keyblade Wielder in training under Yen Sid, but he ran off after learning the worlds were in danger. Mickey shows Ven the star shard he’d been using to travel between worlds and tells him how unstable it is. When he takes Ven’s hand, the star shard propels them in another world.
