Nightingale is a world very different from but still much like ours. Where it deviates is the mysterious Fae introducing Magick to humanity, resulting in a world where Ada Lovelace did not perish to uterine cancer and Shakespeare's plays were not necessarily fiction. Beyond improving and changing human life, Fae Magick resulted in Realmwalkers, humans who explore the Fae Realms. It seems like a very interesting, alternative history to live in, if it weren't for The Pale. Nightingale begins with the mysterious apocalyptic event known as The Pale emerging from the Eiffel Tower, tearing the world apart and scattering folks like the player character across the Fae Realms.
