Jade Dynasty (also known as Zhu Xian (Chinese: 诛仙)) was a free-to-play MMORPG created by Perfect World.

Released in an era where popular MMORPGs were besieged by bots and other problems related to trading of real-world currency for digital goods, Jade Dynasty was notable for replacing traditional click-intensive methods of training with an in-game automation system.

Ever since the shutdown of the official game, there have been many appearances of private servers trying to recreate what was once quite a popular Chinese MMORPG.

Jade Dynasty is set in a world based on ancient China, where the secrets of immortality and martial-arts perfection were fought over by six human factions: Jadeon, Skysong, Vim, Lupin, Modo and Incense.

Their pursuit of forbidden knowledge brought them into conflict with the demigod tribes of the Athan: Balo, Arden, Rayan, Celan, Forta and Voida.

As in most fantasy MMORPGs, the games' different classes, called factions, follow some common archetypes.
