I don’t know if I have anything prominent within my work in progress that’s actually a myth. Like that’s actually completely untrue, or so fabricated it might as well be. Most of my stuff that’s treated like myth and legend is stuff that is true, but isn’t quite like people expected.
Like the God-Hero’s prophesy. So, the first superhero who brought magic to the world claimed to be god. And he is a god, but he’s part of a pantheon he conveniently didn’t mention. He stuck around for a decade to make sure everyone didn’t destroy themselves in the chaos, and then left a prophesy behind. Summarized, he told everyone the world would one day be ravaged by a magic-devouring monster, ‘The Prophetic Devil’, and when doom was nigh, the God-Hero would send his goddess daughter, Rolling Platinum, to earth in mortal form to lead the war against said devil.
So for over a hundred years the whole world has been waiting for this monumental battle between good and evil, and everyone has a different idea of what that means. Some people think the devil will be an eldritch monstrosity of some kind, some thing they’ll just be a really powerful supervillain, most racists/sexists/homophobes/etc insist the devil will be a member of whatever group they hate, organizations and entire nations have used ‘one of them might be the Prophetic Devil’ as a justification to start wars, most countries have laws that legalize the slaying of the Prophetic Devil for anyone who finds the real thing and happens to get the opportunity, and there have been countless ‘devil scares’, where a villain pretended to be the devil, or a civilian or hero was mistaken for them, and countless killers have tried to justify murder with devil law, genuinely and/or as a joke. Nobody knows for sure what they’re looking for, and everyone has an opinion about it, whether they think the devil is that one guy they always hated, or some unfathomable cosmic horror, or just a joke the God-Hero told to troll everyone.
Everybody’s losing their mind looking for Rolling Platinum too. The God-Hero’s churches have all kinds of clubs and competitions for girls who could be the Goddess-Hero. The God-Hero vaguely implied his daughter would have blond hair and blue eyes, so a lot of women and girls with those are favored while others with other colored hair and eyes are discriminated against, and it’s an unreasonably huge debate among the church whether Platinum will have a certain aesthetic or could be literally any woman, including to a point where there are people who will pay or force blond, blue-eyed women to have kids in an attempt to breed Platinum into existence. It was implied she’d have a great singing voice, and maybe be a skilled swordswoman, so many parents force their daughters to learn to sing and use a sword, and now there’s a whole hecking lot of ripoff Platinums running around. Many girls are pressured and pitted against each other trying to be the best Rolling Platinum, and many end up feeling crushed by the system, although some become scarily good swordfighters and end up thriving from people mistaking them for a goddess.
Rolling Platinum and the Prophetic Devil really do exist. The Devil is a magic-devouring monster, but he’s also just a dumpy, goofy, sarcastic, undertrained graduate hero who wants to make friends, do cool magic stuff, and make his parents proud of him. And Rolling platinum is a blond, blue-eyed, singing swordswoman, but she’s also a loud, angry, silly, socially awkward hacker and gamer girl who no one takes seriously enough to believe she could be an angel. The Devil ends up gaining compassion for the world, but not helping as much as he’d like to because he’s taught to believe his help isn’t wanted, or necessary, because he’s what the world is fighting against, and the Angel ends up being bullied into not wanting to help the world at all because she isn’t the perfect girl they expect. Doom is nigh, but it’s not because of some great black and white clash between good and evil, it’s because the world concentrates its attacks on the wrong prophetic figure.
