Each server acts as an individual copy of the game world and players can enter them freely with any character. Servers are all Player versus player (PvP) where open combat among players is common while including all aspects of Player versus environment (PvE) where players can defeat monsters and complete quests. On any server a player may create characters belonging to only a single faction; Guanyin,Fujin or Jinong on any single account.
