Special events - A Vanarch can choose to pay for special events to be held in his territory. These events range from banners flown with the Vanarch's colors and name to parades held in honor of the Vanark. The Vanark can even choose to host events for his loyal citizens, giving out items.
Policing system - A territory task force of NPCs who can enforce the laws put in place. If a player breaks the laws then the NPCs actually imprison the Tera Gold players.
In order to stay in power a Vanarch must maintain a certain level of policy points. Periodically a vote will be taken in order to see if the player currently the Vanarch is to remain as such. If the player is an unpopular Vanark and they wish to remain in power they must embark on Vanarch quests to kill certain world bosses in oder to keep their policy points high.
All of this information points to quite an exciting tug-of-war style political system with different political parties and players vying for control as the Vanarch in their respective territories. Check back often here on OnRPG for more exclusive Tera online Gold
