Zombies are corpses reanimated through dark and sinister magic. These mindless automatons shamble about, doing their creator's bidding without fear or hesitation.

Zombies are not pleasant to look upon. Drawn from their graves, half decayed and partially consumed by worms, they wear the tattered remains of their burial clothes. A rank odor of death hangs heavy in the air around them.

Because of their litter lack of intelligence, the instructions given to a newly created zombie must be very simple, such as "Kill anyone who enters this room."
