Whether you are in good standing with your own faction or not is determined greatly by the alignment system. The basic theory is that you have good relationships with the members of your own faction by killing evil players, you lose alignment by killing good players. Some in red means he is evil. Blue is someone who is in good standing with his own faction. If you kill someone good, you will be closer to being red, killing the natural enemies of your race and red players will increase your standing. The value of a negative hit is much higher than that of a positive one, thus it will take several enemy kills to negate the effects of a single friendly kill. Your alignment appears as the bottom meter in the window where your life, stamina, and mana are located.
