For fantasy are we allowed to use our own urban fantasy au? It's not quite clear on the post - for instance - if I want to write a story in this world but with magical realism added but not use a pre-existing au - I'm assuming that would be fantasy and not supernatural? But if I want to use mythical creatures I have to join supernatural? Like perhaps I have a story about a boy and a phoenix in a like the real world and the phoenix is a shapeshifter and lives forever - would that be fantasy? Or supernatural? Sorry to be so confused.
