An isometric view of the Sons of the Green Dragon antique Chinese Vault, inspired by Fallout game series but in Chinese style. The big and well visible scifi rounded Vault Door at front, and a lush underground oasis with scifi technology that combines with waterfalls, inlaid wooden bridges and Zen gardens. At the center of the Vault, an ancient thousand-year-old tree emanates ethereal green light. Advanced technological structures blend harmoniously with the natural environment. Realistic fantasy style, elaborate details, magical lighting, vibrant colors, scifi technology in the grass, as drawn by Dan Malone
