The Kre caves were named after a powerful earth komorebi named Kre Karson who built them using his komorebi to create passageways through the many rock formations in the Grayrock Canyon. Each cave is just a short passageway rather than a dead-end cave. When asked why they’re completely square, he told them that sarcastically that if they wanted pretty caves, then they could use their komorebi to come down and smooth out every single rock.
