dcd@rkf@ntsy. 1970s retro dark fantasy book cover art, dungeons and dragons style, Wide shot, eye-level viewpoint, two figures in flowing red hooded robes ascend different sections of a vast, labyrinthine stone staircase, their backs turned to the viewer, both occupying the lower and middle ground against towering cylindrical stone structures engraved with large, circular bas-relief faces, the immense architectural elements dwarfing the figures, deep shadows filling the spaces between stairs and columns, the red robes vividly contrasting the dark, weathered stone environment.
