Lao-shan lung

Lao-Shan Lung or "Lao" are gigantic Elder Dragons popularly believed to be the size of a mountain. This giant, slow moving creature would go in hibernation until it's necessary to leave the area.The extremely hard scales on its back develop from the Lao walking directly through mountains. Lao Shan grows as his body receives floating particles from the atmosphere. The red tint comes from the iron deposits near their environment; the blue tint comes from ash particles from the Volcanic Belt. This process takes an untold amount of time, suggesting that Lao-Shan Lungs have extremely long life-spans. Lao Shan Lung means Great Mountain Dragon in chinese.
