Shenlong (Chinese)
Shenlong, is the spirit dragon from Chinese mythology who is the dragon god of the tempest and also a master of rain. He was also five-clawed, which was iconic of the imperial dragon. Chinese empires have admired shenlong for centuries through festivals.
The spiritual dragon is azure-scaled and governs the storms, clouds, and rain, on which all agricultural life depends. Chinese, Japanese, Korean, and Vietnamese people would take great care to avoid offending him, for if he grew angry or felt neglected, the result was bad weather, drought, flood or thunderstorms. Despite this, Shenlong appears to signify a special rank in the splendid robes and regalia of Chinese emperors.
