Higher Purpose
You are driven to exceed your normal limits in one specific pursuit. You must state this exactly as if it were a Code of Honor disadvantage: "Defend all women," "Slay all demons," etc. If, in the GM's judgment, you are unfaltering in your pursuit of your Higher Purpose, you get +1 to all die rolls that pertain directly to the pursuit of your cause. If you deviate from your Higher Purpose, you lose this bonus ... and the GM is free to penalize you for bad roleplaying just as if you had ignored a Code of Honor.
A Higher Purpose must be specific. Higher Purposes such as "Fight evil" or "Oppose authority figures" are too broad to be balanced. In addition, a Higher Purpose must entail genuine risk and inconvenience. The GM should not allow pragmatic Higher Purposes like "Faithfully serve my superiors." All Higher Purposes are subject to GM approval.
