Concept art, detailed, realistic, vivid colors, professional quality, masterpiece, black on black, On a mountain peak, a temple carved from ancient stone is now a place of dark experimentation. The Skyborn, a race of winged beings, once sought enlightenment, but their obsession with immortality has twisted them. In the temple’s grand hall, a Skyborn acolyte stands before a floating crystal, once pure but now corrupted by dark veins. The acolyte, frail and scarred, activates a device of arcane machinery, designed to extract and store life force. As the ritual begins, the temple trembles, and the crystal glows with a cold light. The acolyte’s face is determined, but fear lingers in their eyes, knowing the cost of their pursuit. They seek to transcend mortality, but with each ritual, they lose a piece of their soul, becoming less human and more like the crystal they worship, their immortality a hollow, cursed existence.
