Art style: Semi-Realistic Digital Anime.
The immense, crushing depths of a dark ocean abyss. On the rocky, uneven seafloor, a massive, jagged sapphire crystal emanates a mesmerizing, deep blue bioluminescent glow, illuminating floating marine snow. Medium-wide composition, slightly high angle looking down at the crystal. Cold, localized glowing light piercing through absolute, murky aquatic darkness. Mysterious, awe-inspiring, and profoundly deep atmosphere. Dominant dark midnight blues, bright glowing cyan, and deep sea black.
