Lusternia operates with a PvP (player vs. player) policy with an innovative twist, which is called the Avenger Justice System. Avechna the Avenger has been charged with protecting the prime material plane against oppressors. An oppressor is someone who repeatedly kills or attacks another. What this means is that if you were killed on the prime material plane, you will be under the protection of the Avenger against that person for one real-time month. That person is now a "suspect". The first hostile action against you by a suspect will allow you to call the Avenger once. If you do not respond with any hostile action and die to that person, you may call the Avenger a second time. If you initiate a hostile action against a suspect, the Avenger will assume you are taking matters in your own hands and remove that person as a suspect. An Avenger List is kept for each player to track who is a suspect and if that player can claim vengeance upon another.

In sum, Avenger Justice automates a very tough system of controlling PK (player killing). Potentially, an oppressor who kills someone will find himself dying twice each time he subsequently kills that victim within a 30 day period (assuming the victim never makes a hostile action in return). If that person attacks a victim unprovoked but fails to kill that victim, he will still find himself dying to the Avenger (even if the victim turns the tables and kills the oppressor, that person will die twice, once to the victim and once to the Avenger). Invoking the Avenger is optional and a name on an Avenger List will be deleted from the list if not invoked after the 30 day limit on the name expires.

Exceptions: The Avenger will not protect you if you die on another plane, so travel to other planes at your own risk. Also, the Avenger will not protect you if you enter territory where you've been declared an enemy.
