From the preview:
The Amazons hold sway over the plains, steppe, and wastes bordering the Halodyne lands; these harsh environments hold few natural resources, numerous predators and untold enemies.
These hardened tribeswomen of the borderlands are and have always been nomads, driving their herds of cattle across the chaparral, grass and scrub astride the backs of their exotic mounts.
Besides roaming the borderlands, troops of Amazon warriors bear arms for the city-states and holy Temple-lands living as mercenaries.
War is every Amazons' most faithful companion, for their lands are encompassed by enemies.
