You are a sentient machine.

Clockworks’ bodies facilitate the tasks for which they were created. Most clockworks stand between 4 and 8 feet tall and weigh as much as 800 pounds. All have humanoid shapes, but soldiers sport animal heads—stags, wolves, and lions being the most common. Clockworks who were servants more closely resemble humans, some slim and sleek, others short and portly. Clockworks are made from base metals, and their components have little value beyond maintaining their existence.
