The Legion Deredeo Dreadnought was a fortress in the shape of a warrior, and the Iron Warriors employed it exactly as they would any other piece of a fixed defence — as an anchor around which a killing ground was built. Interring a veteran whose body had failed but whose patience had not, the Deredeo raised autocannon batteries and missile arrays to weave an interlocking canopy of fire that no assault could cross and no aircraft dared. Perturabo's engineers linked its cogitators into the wider firebase, so the interred warrior became a node in a lattice of calculated destruction. Where other Legions sent their Dreadnoughts hunting, the IV Legion set theirs to hold, and few things in the galaxy were harder to dislodge than an Iron Warriors position with a Deredeo at its core. It did not charge; it did not falter; it simply endured, and made the ground before it impassable.
