Subzero Cavern

Subzero Cavern is a location found in northeastern Minearth. Located beneath Shiver Tundra, it is a flooded cavern that is even colder than Shiver Tundra, being less than -20 degrees Fahrenheit at hottest and approximately -80 degrees Fahrenheit at coldest. Having many icicles, this cavern is a landmark. The cave begins to melt about 4 kilometers underground into a completely flooded cave. The water is even colder than the cave, being -135 degrees Fahrenheit at hottest and -190 at coldest and it still does not freeze into ice. It has not been touched by any human due to it's insanely cold temperature. Only the Celestial Crew was able to visit it, but left shortly after due to crew concerns.
