As an Indigenous person raised around these ancient ideas, not only did our ancestors believe in these as real beings, some of our cultures still do! We still talk about the jogah and the other beings coming from a different world to this one, and how we share this realm with humans, we come out at night, the Native tribes out during the day.
My Indigenous human parents will tell you personally that I am not a human. We fully acknowledge this in my family. My brothers know I am their elf brother. That’s just the way life is for us.
Don’t let genocidal colonizers pull the wool over your eyes, they have unicorns and dragons on their royal coat of arms. Iceland has a dragon and giant on their coat of arms. More than 60% of Iceland still believes elves and giants are real beings that exist alongside humans. They even stop construction so they won’t disturb the landvættir.
