Immortal creatures. They are not gods or spirits, but they still have more powers than mortals, so they often became objects of their worship.
You can play our 2D game 'The Crown of Leaves' to find out more information about these creatures.

Tsourai are divided into species, like animals. Here is a list of it, and you can find the pictures with all of them in this folder:

Surface (Shang-La world) tsourai:
►Sualokin - nagas with long muzzles and cute fluffy tails. Their clan is ruled by the King of Potions, Lahkedemon. (this concept was originally created by RayEtherna aka Raesheris, go find her art here http://www.furaffinity.net/user/raesheris).
►Dangas - wax creatures that belongs the clan which is ruled by the King of Ghosts, Bamboo.
They have rugged "square" muzzles, zipped lines of the mouth and big glowing eyes.
► Grahn - ruled by the Queen of the dreams, Sariah. Clan of the Dreams. Normally looks like anthropomorphic creatures that have elegant creased up snout with jagged lines of the mouth, a feather on their napes and wings (for males only).

Padmire tsourai:
► Caspians, winged creatures with "hatchet"-like snouts, funny thin legs and a tail covered with feathers. Can fly, also create living puppets (Jadu). Many of them are aristocrats. Noble class of sort.
► Taba, or simple 'deers'. They are gloomy and physically strong. A lot of them are hermits or choosing a lonely way of life.
They traditionally fight against the demonic ink-trees, that became a big problem for Padmire in general, because they kill everything around - other plants, animals, and even tsourai themselves.
► Maravins, inspired by qilins and/or kirins; anthro creatures with funny ears that is similar to wings, soft muzzles and scales on their body. Most common species for the Padmire. They are gifted in many ways, can take the creative professions (writers, musicians, etc). Some of them also can create a very rare living puppets, Camaroo.
