Sinbad & Ariel - What the Water Gave Me

I know the story is a bit shaky. I'm still trying to find a way to project what I'm thinking into the story. Storyline: Ariel is turned into a mermaid and trapped away in the book at the beginning by Eris. While she is in the book she remains a mermaid. She can slightly see the outside world through the opening of the book and wishes she could go back. Sinbad searches the seas for the book. So he can try to help her but once he finds the book Proteus won't let him touch the book. Sinbad feels very guilty about not being able to help her escape Ariel goes to look for a way out herself and finds Eris. Ariel is nervous but Eris says she cant help turn her back. Ariel doubts her and Eris shows her how she can effect the real world very easily. Eris travels to the real world and impersonates Sinbad as to cause trouble. There are flashbacks where Eris makes a deal with Ariel. I couldn't figure out what to give Eris in return :( Eris picks up the book and shuts it and Ariel transforms. She thinks it will be wonderful to be human again and Sindbad will be happy to see her but when she arrives the city is in chaos and crumbling. They blame Sindbad for the disappearance of the book and sentence him to death. While he is in prison Ariel contemplates what to do. Marina finds Ariel and tells her they are going to kill him soon. (Confusing again sorry) She jumps into the water obtaining her fins again and breaking the curse momentarily. Eris appears and Ariel asks her to send her back into the book to protect Sinbad and the city. Eris is annoyed but agrees. Ariel changes and jumps back into the book. Sorry it was so choppy. I'm still learning. I've been working on this for a long time, never finding the right song, but found it a day ago and was eager to complete it. Thank you for watching and hoped you liked it at least a little :)
