HDRI, A cavernous expanse of blackened stone, its walls glistening with a sheen of molten heat. Veins of fire run like rivers through cracks in the floor, glowing red-orange and sending waves of warmth into the air. Towering pillars rise crookedly into darkness above, their surfaces jagged as if torn apart by claws. Chains dangle from unseen heights, their links glowing faintly, each one radiating a metallic tang that lingers in the air.
