The Lizardmen are an ancient race, created by the god-like beings known as the Old Ones to be the guardians of the Warhammer world. Their age-old civilisation is based deep within the steaming jungles of Lustria and the Southlands, where their mighty temple-cities rise amid the ancient trees and cloying swamps. The bloated Slann Mage-Priests are masters of magic and the original servants of the Old Ones, and it is they who oversee the entire Lizardmen civilisation, guiding it forwards. At the heart of the Lizardmen armies are the powerful Saurus, hulking reptilian warriors spawned solely for the purpose of war. They are revered as sacred warriors of the gods, and each temple-city has an army of them dwelling beneath the temples, ever ready to march against their foes.

Without the guidance of their creator-gods, the Slann work toward the Great Plan that their masters set to restore the order that was present before the coming of Chaos.
