Aurora over a Dragon's Lair in Watercolor

An ethereal watercolor painting of a dragon's lair at night. Soft washes of emerald green, sapphire blue and amethyst purple depict an otherworldly aurora spilling through a crack in the cavern ceiling. A majestic dragon lies curled around a glittering mound of gold and gems, scales iridescent in the auroral light. The cave walls are jagged with stalactites and crystalline pockets that catch glints of light. The foreground features a tranquil pool that mirrors the glowing colors. The scene is painterly with loose, translucent strokes, wet-on-wet textures, granulation, and delicate color bleeds typical of watercolor. Dreamlike atmosphere, calm and awe-inspiring.
