I have Swan Lake Warriors lore.
I'm making Warriors a prince, and Legend and Twilight were soldiers meant to protect him (this is funny to me because these two canonically do not like soldiers and knights). They are the only ones who stayed stubbornly at his side when he was cursed, and so were cursed alongside him.
(Legend likes complaining loudly about how he should have left while he could. He's lying, even if he went back he'd still stay, and they all know it.)
Minish Four and Fairy Hyrule are here, but they aren't cursed. They're just regular magic creatures who are trying their best to help.
Cia is Rothbart, and I'm stealing the motivations from the version that gives me a headache. She wants to marry the boy because she's Like That. And he's pretty. Also she wants his kingdom.
Dark Link is Odile (the person who poses as Odette for the false declaration plot point). Because who else?
Wild finds them while hunting and then panics when he realizes he nearly shot the prince. (He doesn't Twi stops him from shooting them but still.)
Don't know about how the declaration would work, that's a work in progress.
Oh! But I am stealing the bit from the version that gave me a headache were they're bound to that specific lake. He has to be on the water of that lake to get his human form back at night, though it doesn't matter where he is when the sun rises, he'll still turn back. This also means being human is optional.
Also all three boys are bound to Warriors' curse, meaning Wars gets to decide what form they take at night. This makes Legend understandably pissed off.
I'm, still working on the rest. But I have some of the lore figured out. This is what we've got so far! Enjoy!
okay i absolutely LOVE this! the roles might seem"unusual" given their characters/what you said about Leg and Twi disliking soldiers but i think it fits them perfectly - especially if their curse is linked (hah) to Warriors' (which btw, poor Legend, im on his side on that one, i'd be pissed off too if i had no control on my form. Though the idea of being bound by that lake only is REALLY cool)
of COURSE Dark Link is Odile. i don't know why i ever doubted it. and CIA'S MOTIVATIONS... they make sense but im gonna yeet some sense into her
Hyrule and Four not being related to anything going on but being there and trying to help seems really in character and also gives ample opportunity for shenanigans i think. amazing
