1970s Retro Dark Fantasy Book Cover

1970s retro dark fantasy book cover art, dungeons and dragons style, Full-body view from a slightly low angle, two robed figures face each other near the center, one draped in white with hands folded, the other in black, both hoods obscuring their faces, standing on rocky ground beside a dark reflective pool, their mirrored images visible in the water, tall vertical waterfall streams cascade down the background cliffs, mist rising at their feet, deep forest shadows surround the scene, faint golden highlights ripple across the surface of the pool.
