The long is a dragon of Chinese mythology with a hybrid appearance that combines the physiognomy of several animals, namely: the head of a camel, the horns of a deer, the eyes of a demon, the ears of a cow, the neck of a serpent, the belly of a mollusk, the scales of a carp, the claws of an eagle, and the paws of a tiger. On occasion, it takes human form.

The long has the mission of controlling rainfall and the waters of rivers and lakes. Unlike other European dragons, it cannot breathe fire from its mouth... though it can breathe clouds.
