In nineteen twenty-nine, researchers who were studying an ancient people named Oroch asked one of their shamans to draw a map of the Universe. The local sorcerer insisted that the Universe is surrounded by an invisible sphere with periodic holes that Orochs called "the mouth of the skies."

Nowadays, this understanding of the world seems rather funny, but... can we find a better answer to the question they challenged the shaman with?
