Deathseeker rangers wander the world, trying to moderate the balance between the forces of life and death. They believe that obtaining equilibrium between the living and the undead will usher a new age of peace and harmony, where death is no longer something to be feared. However, while they want perfect stability between the dead and they living, they won't hesitate to slay an enemy that attacks them, since their own survival is crucial to reaching this balance.
