Summary

The Ordo Reductor is the Mechanicus order of siege engineering and controlled demolition. Where the Cybernetica builds machines that walk and the Skitarii cohorts hold lines, the Reductor moves planets — its discipline is the mass-removal of matter, whether that matter is a fortress wall, a mountain ridge, or the surface of a world.

Lore

Doctrine

The Reductor’s doctrine is the doctrine of unmaking as preparation. To clear is to make ready for the next consecration. The Cult tolerates this violence because the Reductor performs it in ritual: each demolition is preceded by a Liturgy of Removal, each excavation by a Cant of Earth.
