Hell is a realm beyond the mortal realm (Earth), and is the home of demonic beings called Devils. The capital city of Hell is Sulfur City, which holds the seats to the Low Spheres - the ruling council of Hell. Paradise is a realm of darkness, rough rocks, chaos, death, and lava flows. Everything and everyone exudes wickedness and cruelty.
Above Hell is a strange realm called Limbo, and at the opposite end of Limbo is Paradise. Access to Earth from Hell, is done through neutral locations, like the Golden School.
