You succeed in ridding Sentinel Hill of gnolls, boosting your reputation as an effective gnoll-slayer. In fact, Sentinel Hill's leader, Marshal Gryan Stoutmantle, is so impressed with your skills that he offers you a high-ranking job in Sentinel Hill's militia. On the other hand, the Defias is not so impressed with you. It seems that defeating the gnolls is about to give away the fact that the Defias is hiding in Sentinel Hill.
Take Gryan's offer. Take back up your old career for good. Stick with the Defias. Don't let their position be given away.
