A long time ago.
A part of the forgotten past
In the world of fire and lava, it is the star-planet called Inferno. A land made of active volcanoes that would cause explosions and spread raging flames that burn anything and high-temperature lava. But within that burning no world a certain part of it was like a dead wasteland. Limbs of humans and demons were scattered all over and the black land was tainted with pools of blood. At the center of it was like an island of the sanctuary. This piece of land was covered in thin ice and snow that even the lava itself was unable to melt. Like an everlasting glacier that not even a fire thaws it.
