Night Whisperer

In 3061, a mutation occurred in the earth's core, and prosperous cities were swallowed up by lava spewing from the ground. Human civilization was completely wiped out. In order to survive, the survivors built walls using basalt materials to encircle five vast areas to avoid the threat of phantom beasts. In the process of collecting materials, individual survivors unexpectedly discovered that the bodies that had experienced this catastrophe seemed to have been affected by the energy erupting from the earth's core. They could feel the elements floating in the space, and even be able to drive these elements, and magic returned to the human world again.
