A masterful fantasy illustration of a Gem-Knight Quartz robot, a striking figure in red and gold with bold black and silver accents, standing in a proud, heroic stance. Its vibrant red head with a gold visor gleams, slightly tilted, hinting at curiosity. The robust body, a blend of red and gold with black and silver details, is depicted with an exceptional quality of handcrafted precision, showcasing super detailed armor plates and intricate mechanical aesthetic. The arms and legs, matching in design, are ready for action, with a red, gold, black, and silver sword firmly gripped in its right hand, emphasizing a sense of readiness and alertness in a well-timed moment. The background is a dramatic and ancient Fortress Whale's Oath, rendered as a sprawling, beautiful matte painting with sharp lines and expressive brush strokes, conveying a powerful message. The composition adheres to the Golden Ratio, utilizing a creative angle and attractive background to enhance the robot's majestic presence. Stunning multi-colored palette and harmonious colors create a captivating lighting.
