Jade Dynasty is a free-to-play MMORPG game created by Perfect World. Jade Dynasty recently released its fifth major expansion, Jade Dynasty: Regenesis. It is based on a popular Chinese internet novel called Zhu Xian. 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. Each faction in Jade Dynasty has different skills, strengths, weaknesses and styles of play. Players can become more powerful through 150 levels, high ascended levels and several endgame skill systems (such as the "Chroma" system). As in most fantasy MMORPGs, the games' different classes, called factions, follow some common archetypes. Their names are, however, very original, as they are based on the Chinese novel Zhu Xian's story. There are three races in Jade Dynasty: the Humans, the Athans, and the Etherkins. The Humans and the Athans races each have six classes in total, with the individual class locked onto that race. The Etherkins currently has two classes. These classes are as follows: Jadeon, Skysong, Lupin, Vim, Modo, Incense Mage, Balo, Arden, Rayan, Celan, Forta, Voida, Psychea and Kytos.
