Vitruvius's apprentice is an unnamed character, often referred to as "Idiot". He was the apprentice of the great metallurgist Vitruvius, known for accidentally instilling his entire consciousness into a primed elemental ingot while trying to animate it as a prank. This is what earned him the nickname 'Idiot'. His master Vitruvius attempted to bring him back to life by further study of magical effects on the elemental metal.
