A dark, ominous river winding through a desolate underworld, shrouded in thick mist and shadow. The water is black and glass- like, reflecting eerie glimmers of pale light from an unseen source. Ghostly figures emerge faintly beneath the surface, their forms twisting and fading as if trapped in eternal torment. Jagged, obsidian rocks line the riverbank, their surfaces slick and glistening under the dim glow of ethereal green and blue light emanating from the river. In the distance, the faint silhouette of a hooded ferryman, Charon, stands in a weathered boat, holding a long, crooked pole as he waits silently for the next soul to ferry across. The atmosphere is heavy and foreboding, with the air thick with sorrow and whispers of the departed. The color palette is dominated by deep blacks, muted grays, and eerie shades of green and blue, emphasizing the otherworldly, melancholic mood. Fine details, such as ripples in the water and faintly glowing spectral hands reaching from the depths, enhance the haunting realism of this mythological scene
