Zombies are undead bodies resurrected by an unnatural spirit or necromancer. They are found in dark underground places, such as sewers and caves, and can also be found in graveyards. When slain, a zombie corpse may yield up mort flesh, which can be used as an alchemy ingredient. They are simple corpses filled with evil power to mindlessly do the bidding of their master. Sometimes zombies that were slaves of something are freed from the magical bonds binding them. These free zombies usually walk around, moaning and attacking nearby living creatures.
