Your adventuring career has not gone as planned. Instead of wealth and fame. You find yourself in jail in a small nowhere town called Middlesmith. Fate has served you one cruel twist after another. You are at rock bottom. However, just when you are about to decide that the adventuring life is nothing but trouble and not for you. You learn of an opportunity. You hear that Middlesmith has been ravaged by some sort of sickening. This sickening has taken most of the town. All efforts at traditional and divine healing have failed. In desperation. The town elders have turned to you. You have been offered a new beginning. A chance to clear your slate and a reward. All that you have to do is find a cure for the sickening and save the town.
How hard could that be?
