A hyper-realistic, wide-angle cinematic shot of a Mizukage's office interior. The walls are made of massive, cold grey granite blocks with visible dampness. In the center, a monolithic, sharp-edged throne made of raw, jagged black obsidian that looks like frozen volcanic glass. In front of it, a massive, unpolished stone slab desk with the "Water" symbol (水) roughly hand-carved into the front, glowing with a ghostly blue light. Behind the throne, a panoramic floor-to-ceiling curved window reveals the misty towers of Kirigakure. No furniture, no paintings, no fabric drapes. The floor is dark, polished stone. Moody, low-key natural lighting coming from the fog outside. 8k, photorealistic, brutalist interior design, dark fantasy atmosphere.
