Bounty in the Bog

From the front page: The Soldiery has grown weary of dealing with a particularly nettlesome band of miscreants who have holed up in the Flooded Forest to the south. And so, you have been called upon to quell their activities so that trade along the North Road can resume unmolested. However, in so doing, the truth behind their activities reveal that much more than simple banditry is at hand. Will you be able to stop it? An adventure for 5th-10th level characters.
