The '''{{PAGENAME}}''', also known as the '''Iron Guardians of Tizca''',{{Fn|3}} is a variant of the [[Castellax Class Robot]] used by the [[Thousand Sons]].{{Fn|1}}

==Overview==
Never ones to squander their ranks in bloody attrition, the Thousand Sons Legion employed unliving battle-automata as obedient, resilient, and ultimately expendable shock assault units. As with every other facet of warfare, the Legion believed their psychic arts could improve upon these robotic weapons – and with the secret assistance of their allies in the [[Forge World]] of [[Zhao-Arkhad]], the sons of [[Magnus]] created the Castellax-Achea. Rather than the cybernetic brains or [[cognis-wafer]] blocks employed by standard automata, the Castellax-Achea was governed by a psi-sensitive crystal matrix – an illegal [[heretek]] innovation that allowed the Legion's [[psyker]]s to directly manipulate these robots like murderous puppets with a degree of limited self-will.{{Fn|2}}

==Equipment==
These [[Battle-Automata]] were fitted with a crystalline psi-control matrix that allowed [[Psyker|psychic]] [[Space Marine]]s to manipulate them like puppets in a fashion far more seamlessly than standard [[Legio Cybernetica]] technology.{{Fn|1}} The robots were armed with either a [[Mauler Bolt Cannon]] or [[Æther Flame Cannon]].{{Fn|2}}
