old book illustration, impasto, glow, rim lighting, A powerful mage, robed in deep blue and silver, stands at the center of a grand medieval castle chamber. His weathered hand grips the Staff of Power, glowing with ethereal light. His face is a mix of shadow and shimmering stardust, with textured, otherworldly skin. Around him, the walls are covered in ancient runes and enchanted symbols, and flickering candles cast long shadows. Small, intricate details of potion bottles, magical artifacts, and floating arcane symbols surround the scene, giving it a deeply mystical and ancient atmosphere. Dramatic vibrant dark color scheme
