Crystal Entity in a Watercolor Fortress

An ethereal crystal entity suspended in a grand medieval fortress courtyard, painted in watercolor with soft washes and subtle color bleed. The entity is humanoid or amorphous, formed from translucent crystal facets that refract light into pale blues, greens, and lilacs. It glows gently, casting tiny prisms across damp stone walls. Surrounding fortress features ancient stonework, towering crenellations, ivy, torches or lanterns, arched doorways, and fluttering banners. Damp moss, mist, and warm amber torchlight contrast with the cool crystal glow. The scene has a dreamlike, tranquil mood with delicate textures and painterly edges typical of watercolor. A light rain or mist enhances translucency and the interplay of luminous crystal against rough stone, focusing on reflections and refractions across surfaces.
