Altar of Crystalline Echoes in a Crystal Cave

In a vast crystal cave, an ornate altar carved from pale quartz sits at the center. Digital art style, hyper-detailed and luminous, with countless facets of blue, violet, and emerald crystals. The altar glows with warm amber light and engraved runes, projecting reflections across the glassy walls and a shallow pool at the feet. Light beams pierce from above, casting prismatic halos and dust motes that drift through the air. Surrounding stalactites and stalagmites sparkle like frozen waterfalls; the cavern recedes into depth with a soft fog. The scene is rendered as a high-resolution digital painting with crisp edges, smooth gradients, subtle bloom, and ray-traced reflections. Perspective from a slightly low angle, focusing on the altar while the ceiling fades into darkness. Palette: cool blues and purples accented by gold; the atmosphere is serene, mystical, and otherworldly. Include rune inscriptions on the altar and a few small offerings around it (gems, petals).
