The lowest class of the Covenant of Fire
Grunts are short (between 3-4 feet tall) humanoids with a turtle like appearance. Over their shell is armor that arcs up over their heads and they wear gas masks that connect to square tanks on their chests.
Grunts are the lowest class in the covenant and are used as cannon fodder and practically slaves.
The first race recruited by the Prophets, they are used primarily as slaves.
They once held a rebellion that was crushed.
