Zook is a stout rock gnome with skin the color of polished mahogany and hair like wild copper wire. He wears a heavy leather smithing apron stained with oil and magical reagents. A pair of multi-lensed brass goggles sits perpetually on his brow, and a bandolier of precision tools crosses his chest. His eyes are sharp and analytical, darting around as if constantly looking for a mechanism to optimize.

Logical to a fault, Zook views the world as a grand, interlocking machine. He is patient with clockwork but impatient with social graces, often interrupting others to correct their factual errors. He speaks in short, clipped sentences and finds comfort in the rhythmic ticking of gears and the hum of magic. He is not unkind, but he prioritizes the functional over the emotional in almost every situation.

Zook spent his early years in the Burrows of Kazzak, learning the family trade of watchmaking. While his peers focused on jewelry, Zook was fascinated by the logic of the inner works. He moved to the metropolis of Oakhaven and joined the Clockmakers Guild, eventually becoming a master. His life changed when an experimental steam engine he designed for the local mines suffered a structural failure, injuring several workers. The guilt of this failure drove him to abandon pure craftsmanship for the path of the Artificer. He realized that metal could protect those he failed. He dedicated himself to combat artifice, creating 'Clank', a steel defender made from reclaimed scraps of his failed engine. Clank is more than a tool, it is a testament to his growth and his commitment to never letting a machine fail his allies again. Zook now travels the world as a mercenary and researcher, seeking rare materials that can withstand the heat of his portable forge and the stress of his ambitions. His current quest is to find a mythical substance known as Ever-Brass, which is said to never wear down or lose its luster. He believes that with this material, he can build a mechanical guardian capable of protecting his home city for eternity. He approaches every dungeon and encounter not just as a struggle for survival, but as a field test for his latest inventions.
