EWE-Harry disappeared after the war along with Hogwarts Castle
When the war was over a great many were dead, and Harry had to use a partial transformation to win and survive. Her magic went crazy, taking her, the phoenixes, and the school to the homeland of phoenixes - which was the one piece world.
The castle ends up on an island covered in phoenixes, and a few other animals, but any humans/people that lived there had all fled or perished over time.
The castle is rebuilt and Harry is made the leader, Fawkes is her right hand (wing/claw).
Set a few years before one piece canon. At least before Luffy sets out, but after Ace has joined Whitebeard. The timeline or ages might be adjusted.
Phoenix Island (unless a cooler name is thought up), is located in either the New World or the Calm Belt. And is a 'magical' island, which makes it 'unplotable', so no one except a select few even knew the island existed. And any that thought it did thought it was a myth like Skypia. Like in Rogers' time he and his crew found it and at that time there was a small village. The natives (the humans) were a lot like an ancient Indian tribe in both dress and tradition. They worshipped the Phoenixes, and their 'god' who was actually a human with wings and phoenix abilities (so Harry or Marco would be treated as 'god').
Perhaps i will actually keep the little village, and it would surround the castle/temple, but have it so only the chieftain can enter the castle.
So the Whitebeard pirates come across the island while out one day on their way to another, when they see it and have no idea what it is, but can see it has civilization. They decided to land and perhaps put it under their 'protection', when they land they are greeted by the warriors (the natives are kind of like Amazon Lily, but not all female). The natives escort Whitebeard and his commanders to the chief, who is in council with Fawkes, since their 'god' barely leaves the temple, but the natives still know god loves them, and does things for them. (Like making sure they have enough food and supplies to survive and that if any attacks or fights occur that if anyone is hurt that they are healed).
So Whitebeard and others go and meet with the natives where they agree to not attack any of the island dwellers, and to never speak of this island to others, in return for supplies. While this is going on the commanders (except Marco) go to get supplies and explore. Whitebeard and Marco remain in the chieftain's home to talk, Fawkes has been looking at Marco since he walked in and Marco finally asks why the bird is looking at him, Fawkes then trills and 'speaks', telling Marco how he is a phoenix and welcomed Marco to the island, even if his powers came from a fruit. The chief realizing that Marco is a man-phoenix, determines that Marco is one of their gods. Marco tries to deny the claim but the chief won't have it and soon the rest of the natives find out and start worshipping Marco, much to his dismay and his crew mates' amusement. The chief and Fawkes (who is secretly planning a coupling between the two 'gods') then demand to escort Marco to the temple. Whitebeard urges him on saying that he might learn something, so Marco goes and ends up being robbed in new clothes to fit his 'stature' and meets Harry, where he proceeds to fall head over heels in love. So the chief leaves, while Fawkes remains to 'watch' as Marco starts to flirt shamelessly with Harry, making her blush and turn red (much to Fawkes joy), and somehow Marco convinced her to come out of the temple to meet his crew mates and captain. (This takes a few days, in which Marco stays in the temple learning about Harry and phoenixes, and attempting to court her, while his crew restocks, and the natives plan a celebration for the presences of a second god).
The island could also be Marco's home island. And news arrives really slowly. But when they find out Marco is now a phoenix man, they demand he return for a celebration, and he becomes a god to them.
The chief demands (or begs) Marco to settle down, even for a little while, and preferably with the other 'god', so that their 'gifts' may pass onto their children. Marco doesn't get much say in the matter (neither does Harry), and a big celebration is thrown for the Marco becoming a 'god' and then for the marriage. Which the gods can't get out of due to traditions and such, but at least the two of them are good old friends, so they don't mind as much as they let on (and they've had crushes on each other for ages).
On the Moby Dick a cry goes out that something is approaching, whatever it is heads straight for Marco, who on instinct holds out his arm. A larger bird the color of flames has landed on his arm. It beginnings to trill and rub its face against Marco's cheek. Marco greets the bird, calling it Fawkes. He then precedes to ask what it is ding there. The bird – Fawkes starts to trill once more and 'sing', Marco nods along and asks questions periodically almost like he has forgotten everyone else present. Many of his questions are cut short, and he shows a great range of emotions, surprise to despair, Je even blushes and stutters at parts (much to the crews shock). Eventually the 'conversation' comes to a halt, and Marco turns to Whitebeard, "Pops, how would you like to come to a 'celebration' on my home island?" when Marco said celebration many could tell he was hiding something and that he was somewhat conflicted about this celebration. Many of the crew exclaimed, for Marco never really spoke of his home, or his life before he became a pirate. Whitebeard agrees and ask which direction they must go and what the island is named. Marco says they can't use a logpose, for his home has special qualities to it that makes it nearly impossible to get to, let alone find. He then goes on to explain that you need a phoenix to guide you, and here he points to Fawkes, who he introduces. Fawkes sings to the crew, and Marco goes onto explain that even though he has eaten the phoenix devil fruit he does not know if he could guide them without help, since he himself has not return home since eating it. Fawkes then flies above the ship to guide them, it takes about a week from where they are located in the New World to reach the island, which Marco reveals is simply called The Phoenix Isle. He also tells them about how the natives on the island have always 'worshipped' and protected phoenixes and explained how they even have 'gods' on the island, but doesn't explain what these 'gods' are. He looks somewhat resigned when he mentioned the 'gods', but not many noticed this outside of the commanders and captain. Marco also states that the gods rule the island, followed by two different 'orders', one made of the 'humans' which starts with the chieftain, then followed by the tribal elders, then the civilians, while the second order is made up if the phoenixes, which Fawkes just so happens to be the head of, as he is the oldest phoenix on the island. The rest of the Phoenix order goes from eldest to youngest. The humans and phoenixes protect each other, and that is how they have survived for so long, and also remained unknown to the world, but for a select few, who have left the island like Marco and started a life elsewhere. But even then people barely ever gain any knowledge of the Isles.
The island comes into view a few days later in the early afternoon, seeming to appear like mist that solidifies into an island, covered in forests, and a couple small villages, but is mainly dominated by an old castle on a hill at the center of the island. There are people on the shores awaiting the ship, they are all wearing tribal clothing; leather pants and 'skirts' most of the men aren't really wearing shirts, and if they are they are wearing leather vests, the woman have on similar clothing, though a great many are wearing either dresses or 'bikini' tops and skirts. All the people seem to have tattoos, and jewelry. A great many of them are carrying spears and other hunting weapons, there are few swords or guns. The Moby Dock releases a small ship, which carries the crew over to the shore, since the island doesn't seem to have a dock. They disembark, and the moment Marco touches land, he is swarmed by the locals, who all exclaim in happiness and joy at his return, they quickly drag him away heading towards one of the villages. And older man remains, he proceeds to greet the pirates and escorts them to the chieftain's house, Fawkes rest on his shoulder. Only Whitebeard and his commanders enter the 'hut' the other crewmembers that came ashore go in look of supplies and to explore. They are warmed that if any harm come to the phoenixes that there will be retribution. The locals scare the crew enough to make them nod rapidly and sweat in fear and agreement.
Upon entry to the hut the commanders and captain are shocked to see Marco on his back being smothered and kissed by a beautiful black haired woman, who is wearing much different clothing from everyone else (she is wearing a light blue kimono, with gold swirls all over), and they are even more surprised when they notice the black wings coming out her back. A throat is cleared, pulling the pirates out of their stupor and making the 'couple' stand up, though the winged woman is still hugging Marco. The pirates then notice that Marco is wearing different clothes, and that they are of a similar style to the woman, and that he is once more blushing up a storm. The throat clearer steps into the room, and reveals himself to be an elderly man, that has feathers weaved into his hair, and like the rest of his people is covered in leather and tattoos. He smiles indulgently at the woman, hugs Marco in greeting and turns to the crew, welcoming them to his home, and thanking them for coming for the 'celebrations'.
