Random mod?
In Brokenblades you travel toward a place named the edge of the world. Sadly this is a mystical place that only few know. To represent this, the group have a % chances to find the edge of the world. (This score can be known by consulting sign posts along the road) This score is tested each time the fellowship zones. If the check is successful, the fellowship finds their objectives if not the engine keep cycling events/maps in a random sequence simulating the unpredictable journey.
