Some environments are also rigid and structured just like the crystals in Mood Rings, but yet, are also subject to change depending on the temperature just like the colors of the rings. Instead of the color changing, in this case, the ground and structure changes. The roads begin to slope forming hills and the homes that once seemed immobile suddenly moved and no longer have the same location. Now the infrastructure of a town starts to collapse all because of the changing of temperature in an environment, but how?
