Legends of Lady-Land

In the stories CHYOA: Lady-Land Edition and Life in Lady-Land we explored what a world where everyone is female might look like. However what of it's history and mythology?

As a quick introduction for people unfamiliar with previous entries in this series:

One-hundred percent of humanity is and always has been female. In spite science having no explanation as to how, lesbian sex can cause pregnancy IF neither partner is pregnant and orgasm is caused by direct skin-to-genital contact.
