Create a highly realistic image of a Setting: A deep, dark cavern with rocky walls and stalactites. The lighting is dim, provided by torches or glowing crystals on the walls. 4 Characters: Pedro, Lívia, Thiago and Fernando descending a stone staircase or using ropes, with expressions of determination and caution. They should be visibly united, showing their team spirit. Additional elements: Impressive details of the cave, such as ancient inscriptions on the walls, small underground streams, or creatures lurking in the shadows. The color palette should be somber, with shades of gray, dark blue, and touches of golden or orange light from the torches.
