Alignment in Darkfall is a numerical value used to say something about how good or evil you're regarded by other characters and by guard towers. You gain alignment by killing evil characters, and lose alignment by killing good ones. Your alignment is always displayed on the health window, on the lowest bar. You can mouse over it to see your current alignment status.

Players of opposing factions will always be considered evil to you no matter what their alignment is. To see if a player is considered good or evil, just target him. If his name appears in blue, he's considered good and you will take an alignment hit for killing him. If his name is in red, then you gain alignment by killing him.

If you attack a blue character, you will go rogue for a few minutes. This means that in that time, other players can kill you freely no matter what your alignment is.

Hitting players in your party or your clan will not carry any alignment penalties, or turn you rogue. If your clan has declared war on another clan, you won't take an alignment hit for killing these players, nor will you turn rogue.

If you turn evil (red) you will respawn at a chaos stone when you die. There are no guard towers at chaos stones. To become good (blue) again, you have to kill evil (red) players.
