Dreadnoughts are war incarnate, towering machines that advance forwards with thunderous strides, fiery death roaring from the myriad of heavy weapons mounted on their hulls. They are terrifying foes, fighting with all the skill and ferocity of a Space Marine, but combined with the durability and firepower of a battle tank.
Dreadnoughts are often mistaken by mortal observers for huge suits of battle armour or robots; they are similar to both and yet neither. Dreadnoughts are a combination of armoured walker and cybernetic life-support system; their pilots are neurally linked straight into the Dreadnought's cybernetic systems, and are able to use the walker as if it were their own body, although they are permanently entombed within its Ceramite skin until they are destroyed.
