Clockwork Serpent Spy

Engineers, technologists, and mechanically gifted wizards employ clockwork spies-tiny, spiderlike constructs capable of recording and playing back audio-to surreptitiously surveil their enemies or steal secrets from competitors. Their spindly bodies and delicate components make them unsuitable for combat; in fact, most builders construct clockwork spies with a self-destruct mechanism to ensure the spies' meddling can't be traced back to them.

Intricate, complex machines, clockworks are built with care by highly skilled engineers. Though their creation involves some amount of magic, they're primarily mechanical, packed with precision-tuned gears and springs working in concert.

The sturdy mainspring within a clockwork must be wound to provide the energy needed to power the device. Some larger clockworks contain a series of springs for different limbs that each need to be wound. A clockwork's crafter creates a unique metal key while building the clockwork; winding the clockwork usually involves inserting the key into the machine's back and turning clockwise. Larger clockworks require greater strength to turn the key, and typically have larger keys to allow for more torque-some even accommodating a team of winders rather than an individual. Programming a clockwork requires both the key and the knowledge to set the program correctly, information usually reserved for the clockwork's creator or owner.
