You can never learn to use magic, and you react badly to any user of magic. Make a self-control roll whenever you are in the presence of magic. This roll is at -3 if you are to be the target of friendly magic, and -6 if you are the target of hostile magic. (The magic does not have to be real, if you believe in it!)
You are deathly afraid of infection, or just of dirt and filth. Make a self-control roll when you must do something that might get you dirty. Roll at -5 to eat any unaccustomed food. You should act as “finicky” as possible.
Make a self-control roll each morning upon awakening. If you fail, you suffered nightmares; this costs you 1 FP that you can only recover through sleep. On a roll of 17 or 18, you are left shaking, and are at -1 to all skill and Perception rolls for the entire day.
You are terrified by the idea of death. Make a self-control roll in the presence of any dead body (animals don’t count, but portions of human bodies do). Roll at -4 if the body is that of someone you know, or -6 if the body is unnaturally animated in some way. A ghost (or apparent ghost) also requires a roll at -6.
You may fight – you may even start fights – but you may only use deadly force on a foe that is attempting to do you serious harm. Capture is not “serious harm” unless you are already under penalty of death or have a Code of Honor that would require suicide if captured. You never intentionally do anything that causes, or even threatens to cause, injury to the uninvolved – particularly if they are “ordinary folks.”
