Cartonia

You become more and more sluggish but your thirst for blood is never ending. Eventually you start to track another victim across a bridge. You feel yourself sieze up, however, and tumble over the side of the bridge. As you hit the water and begin to sink you see the homeless man looking down at you searching for the sound of the splash. With the last of your control you trigger the home made crossbow still clutched in your hands. It’s a critical hit and your last victim falls in after you. This is somehow little comfort to you as all grows dark and you are, again, no more.
