These automata represent the current pinnacle of the Tekne developed within the City States. While the creation of the bodies and their power source had long ago been theorized and even tested, the method of control on a battlefield is what eluded even the brightest minds of the Scholae. The current advances within the field of Phlogiston engineering have allowed the Scholae practicals to synthesise crystals that somehow retain communication even when separated. Ensconced deep within the body of these mechanical warriors, they allow a skilled Mechanist to convey orders to his regiment through the careful modulation of the energies he applies to his own master crystal. The result is a formidable, if inflexible, formation of fearless warriors who deliver death without fear, conscience or fatigue. In many ways, the perfect soldiers.
