ever 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 psykers to directly manipulate these robots like murderous puppets with a degree of limited self-will.

This multipart resin kit builds one Castellax-Achea Automata for the Thousand Sons Legion, armed with an Æther-fire cannon. This elegant battle-automata is covered in the iconography of the Thousand Sons, such as sculpted flames and scarabs, as well as mechanical details including exposed cabling, hydraulic pistons, and the psi-sensitive crystal that serves as the robot's 'brain'. It also boasts an impressive degree of posability, with a great range of motion in the legs, waist, and arms, as well as sharpened force claws which can be modelled closed or open and include in-built bolters loaded with asphyx shells. The automaton's primary weapon, its shoulder-mounted Æther-fire cannon, is connected to its power pack by thick industrial wires.

This kit comprises 29 resin components, and comes supplied with 1x Citadel 60mm Round Base. This miniature is supplied unpainted and requires assembly – we recommend using Citadel paints.

You will need a copy of the Warhammer: The Horus Heresy – Age of Darkness Rulebook and the Liber Hereticus: Traitor Legiones Astartes Army Book to make full use of this model in games of Warhammer: The Horus Heresy.
