The sorcerer-kings of old could and would employ common soldiery of course. But that's just to be practical. When allowed to play, and when organised in their efforts they made (more literal) puppets. Programmed with knowledge of how to fight, and laden with more arms (if you're creating something new you may as well make an improvement while you're there), these fearless automatons, clad in easily made metal armour riveted to their frames can become cost efficient if done in the right way. So they did, and their legions of dolls marched against their foes. If there was enough wood and metal to be able to build and armour such a thing, nothing would stop them from making titan-sized marionettes. There is no need to ask why, of course, for what are walls if they can just be flattened. Instinct: To obey

• Destroy something significant and important
• Suffer a malfunction and destroy everything in a blind fury
