I grew up in California’s central San Joaquin valley, and in the winter, the closest thing we had to harsh weather was very, very intense fog. We called it “tule fog“, and some days it would be so thick that you couldn’t see more than a few yards ahead of you, and it felt like you were underwater. As a kid, it was very easy for me to imagine the fog having supernatural properties, and to imagine that the ground ended only just a few feet beyond the edge of where I could see. The earliest ideas about the Empyrean’s Deep Winter region probably started in those daydreams.
