Earthbreaker

Allow this event to play out naturally over the course of a few in-game weeks as described in the original adventure. Continue to allow the steward of the fort to roll checks for weekly events. The PCs will eventually want to get rid of the local hero. They have any number of options to accomplish this (deception, pleading, threatening, etc.) but, as with the snake oil salesman event, as long as he leaves Fort Rannick the PCs receive a victory point.
