The ending starts with this playing in the background (https://www.youtube.com/watch?v=bItsQnOxds0) before zooming in on Master Xehanort frozen on the ground of Kingdom Hearts itself with his hand reaching out after defeat in a pose similar to the one Ventus is in during Birth by Sleep's ending. A single tear flows down his face, while the camera drifts away into the distance revealing the main cast gathered around him in a circle, followed by the rest of the Final Fantasy/Disney cast that has appeared throughout the series gathered around them in a larger circle, all gathered in groups of their worlds. Before the look deeply into the night sky as Xehanort's heart is released, but it's not like the others we've seen released by heartless/nobodies. Xehanort's hearts is black and bigger than the rest before it shatters into thousands of tiny little pieces, almost like dust. Then it fades to black and we see them all return to their original homes and see classic moments from those characters, like Wendy and her two brothers in Peter Pan tucking themselves into bed and Simba looking into the stars on top of pride rock. At the very end of it all, we see Ven, Terra and Aqua return to Radiant Garden, Lea, Roxas, Xion and Namine return to Twilight Town and at last, Sora, Riku and Kairi at Destiny Islands at night before revealing the text within the stars "One sky, One destiny".
