In a drought-ravaged apocalypse, I kept our entire apartment block alive with my “watermaker” ability. But when I grew weak, my neighbors shattered my limbs and turned me into a living water source. Later, when raiders stormed in, they dragged me out to take the blade for them, only to realize that even my severed arms could still produce water.
