SQ control clockworks, dream
Any clockwork that comes within two miles of a brain gear immediately falls under that brain gear’s control. If more than one brain gear attempts to control a clockwork (or if the clockwork is under the control of another brain gear or overseer), each gear must make an opposed Intelligence check; the winner gains control of that clockwork. When a clockwork moves more than 2 miles away from a brain gear, it continues to perform the last order given to it, but there is a 25% percent chance each hour that it ceases to function, collapsing into a pile of junk. If a brain gear later moves within two miles of the destroyed clockwork, the clockwork can reactivate if it has the self-repair ability. Otherwise, it remains destroyed.
A brain gear in control of at least one clockwork can, as a free action once per round, use that clockwork to perceive the world through its senses (such as seeing the area surrounding the clockwork). This ability has a range of 2 miles. If a brain gear controls multiple clockworks, it can instantaneously jump from clockwork to clockwork, keeping tabs on all of its thralls and perceiving the world through their senses. A brain gear can switch control from one clockwork to another once per round as a free action. A brain gear uses this ability to give commands to its clockworks, allowing the usually mindless creatures to fight with highly coordinated tactics. Each clockwork is capable of receiving roughly 100 words worth of orders. Anything beyond that is too complicated for the clockwork to handle.
The brain gear has a limited ability to send psychic messages. Once per week, it can create an effect similar to a dream spell (caster level 10th). The brain gear can contact multiple creatures by designating a generic creature type, such as ogre or human. This designation affects every member of the target type within a 2-mile radius of the brain gear.
Organization solitary or troupe (brain gear plus 4–12 clockworks)
The original brain gear began as little more than a collection of gears, chains, counterweights, and levers, but was enhanced and grown into a controlling intellect through a process very similar to flesh golem creation. A brain gear in its true form resembles nothing more than a copper or gold box or cube that shines with a pale blue light. It is immobile, cannot attack, or speak.
A brain gear is designed to control the actions of all other clockworks created by the caster, relieving the creator of having to oversee simple operations of the clockworks. A brain gear has no real attacks. It uses its clockworks to protect and defend it. Brain gears can be programmed to instruct clockworks to perform up to 20 specific tasks and can be programmed to instruct clockworks to react to certain situations that it perceives. It is rumored that some brain gears occasionally develop an evil intellect and turn their charges against its creator.
