Towering Gothic spires emerge from violent ocean waves, creating a supernatural fusion of architecture and nature. Purple moonlight pierces through stormy clouds, casting an ethereal glow across the cathedral-like formations. Dark waters surge and crash around the structure's base, while crosses atop the spires reach toward the turbulent heavens. Mysterious bioluminescent light radiates from beneath the waves, suggesting ancient secrets lurking in the depths of this fantastical seascape.
