No creations of the Spire embody both the Directorates pursuits of efficiency and the Sovereigns quest for perfection as does the Siegebreaker Behemoth. Its limbs are designed to dig, climb and still strike with such force it cavitates the very air, producing a thunderous boom that dwarfs the sound of its impact, shredding metal, pulverizing stone and obliterating flesh. Its sinuous serpentine body is almost nothing but muscle and armour, sacrificing everything for power, mobility and durability. Its nervous system is a complex mix of simple systems that govern its movement and complex self-referencing pain and pleasure receptors attuned only to its hearing. This is intentional, for its control is established by frequencies known only to its master, who dispenses pain or pleasure ensuring the compliance and good behavior of this unstoppable behemoth.
