Kali The Terrible, Kali The Ferocious

Only in extensive stages of decay can the dead be told from the lepers. The dead are greater in number now, and even the lepers look human when compared to the dead. But that is only if you get close enough to look into the eyes. The faces in various stages of wet and dry rot, the raw ends of bones rubbing through skin like moldy cheesecloth, the cancerous domes of the skulls are the same. After a certain point lepers could no longer stay alive begging in the streets, for most people would now flee in terror at the sight of a rotting face. As a result the lepers were dying, then coming back, and the two races mingled like some obscene parody of incest.
