A digital painting depicting a dark and sinister landscape inspired by the Dark Souls and Grimdark aesthetic. A solitary astronaut, standing before a malevolent ancient tower. The tower is etched with mysterious, luminous runes and encircled by floating, ominous rocks. Overhead, the sky churns with oppressive clouds hinting at an approaching storm. The terrain is harsh, strewn with sharp rocks, and permeated with a sense of desolation. The color scheme is dominated by dark grays, deep oranges, and intermittent flashes of teal from the glowing runes. The digital art style should be detailed and atmospheric, with strong contrasts, intricate textures, and a palpable sense of decay and forgotten lore.
