This is a world of liquid magma, a paradise of flames.
This is another vast cave, awash in light. The outermost part of the cave is a ring of rocky ground, six or seven meters wide, with a large lava lake in the center. At the boundary, the high temperature causes the rocks to form peculiar crystals, preventing the lava from eroding the rocky ground. Bubbles continuously rise from the bottom of the boiling lava lake, bursting at the surface. Each burst sends a trail of flames surging towards the sky. The scorching heat permeates the entire cave, even distorting the rays of light in the air, draping the surface of the lava lake in a haze of colours.
In this world of high temperatures, it is not empty or monotonous. Numerous fire elemental creatures wander in the lava lake, frolicking on its surface, or disappearing into its depths. The lethal lava that can easily kill ordinary creatures is a paradise for fire elemental creatures.
