Idea 25 HP x POTC(Pirates of the Caribbean all)

Elizabeth Swann or any HP parring and either polly or Elizabeth becomes a friend/sister

Obviously there is magic in the POTC universe so this works and I really want to see a pirate fic

Because of the 2nd wizarding war the Statue of Secrecy broke and after awhile jealousy started a war with the non magicals. At the start of the war Fem Harry(Dahlia) pulled a Newt Scamander for both magical creatures and those with creature blood(for those who didn't want to fight) after the world dies and Dahlia(forever 19-21) is the only one left and a talk with Death(for if HP parring or just a second chance in a new world talk) she goes through the Vail. Once in the POTC universe she is now a toddler and meets Calypso who not only knows her story but also adopts her(could also do dad Davy Jones) Calypso also helps her terraform/make an island for the magical creatures/blood and helps hide (her house and the fog/swamp from POTC 2 is a front) and do upkeep till Dahlia turns 16 cause by then she would have enough magic to make wards to do it this way only those with good intentions or with thier permission can access the island though the rare few who got passed that had neither of those requirements got eaten😈. After the wards were set and stabilized Calypso encouraged Dahlia to go out to sea with a compass that always points home(one piece) and explore the world and maybe save some of the creatures from that world for the island. While out exploring(16 2 and a half years before the first movie she is a year younger than Elizabeth 19) she meets Jack who she butts heads with at first because he got her labeled as a Pirates and almost gets her executed after they escape and end up on the same ship they start to get to know one another now he reminds her of Sirius and they start to see each other as siblings and start to travel together. During their travels they could meet the reborn/deaged Hp characters maybe Dahlia could start a crew with them after a year of traveling with Jack so half a year before first movie. At the start of the first movie after Jack lands on the deck he contacted Dahlia with a communication mirror to come help him though her main ship doesn't get there till after he escaped with Will. Dahlia was already there for a supply run and saved Elizabeth though she changed her looks(Metamorph her default is white hair and gold eyes because of MOD) by the time Norington got there cue confused😵,shock😳 and intrigued🤔 Elizabeth though she says nothing and mock betrayed😤 Jack so she saw everything with Will and was just in the background laughing😂 though she would have intervened if he was at life threatening risk. Before she follows the idiot duo😈 scence she is drawn to Elizabeth could be platonic or romantically either way she wants to ensure she is safe so she gives her a enchanted braided cord bracelet or something that will let Dahlia know if she needs help/saving and after Elizabeth is saved she asks for something that could let her know for Dahlia, Will gets one for both the girls who he likes(Elizabeth) or sees as sisters(both or Dahlia). You can figure out how to incorporate Dahlia and co in the movies
