A vertical, 9:16 aspect ratio, hyper-realistic portrait of a sleek humanoid cyborg composed entirely of obsidian panels, standing centrally with equal negative space around it in a barren, lifeless Mexican desert. It is the darkest era of the universe --no stars, no moon, and no other life--just a faint cosmic gloom. The cyborg’s smooth volcanic glass plating reveals subtle, purple-hued bioluminescent circuitry beneath the surface. Its recessed eyes reflect a profound, sorrowful emptiness. A metallic cruciform pendant dangles quietly against its obsidian chest, catching the minimal residual glow drifting through boundless darkness. The scene is rendered with exquisite detail, stark contrast, and a soft, muted illumination, creating a haunting, melancholic atmosphere as the lone figure stands witness to the silent void of a long-gone world. –ar 9:16
