You have issues with mood swings. You are frequently bursting into fits of rage and have trouble containing your anger. It's like a constant fire burning inside you, threatening to throw your entire mind into a blind rage. This trait is used every time you are attacked, hurt, wounded, insulted or otherwise provoked. The Keeper can use it either as a penalty for your other actions, or make a check against the trait to see if you fly into a fit of rage.
