Underwater Paladin in a Watercolor Cave

An armored paladin in gleaming plate armor stands knee-deep in an underwater cave. Sunlight filters through the turquoise water in golden shafts, illuminating runes on the armor and a holy sword at the paladin's side. The cave walls are encrusted with coral and seaweed, with schools of tiny fish weaving through the scene. A soft watercolor style uses washes, gentle edges, and fluid gradients, with bubbles rising and light refracting in rippling patterns. Palette of cool blues and greens accented with warm gold highlights; painterly brushstrokes suggest wet-on-wet watercolor on textured paper, creating a serene, sacred, dreamlike atmosphere.
