Zaterra was home to Reptile's race of Saurians before it was annexed by Outworld through ten consecutive victories in Mortal Kombat. It used to be ruled by a matriarch. Her influence on the other members of the Saurian race is so strong that over time, they begin to revert back to a more primitive consciousness, the longer they are separated from her presence, which also affects their ability to maintain a humanoid appearance.
