Master Zacharius's only apprentice, he is the symbol of a firm and rational stance. He is the only talented worker to whom Zacharius has been able to entrust his privacy and all the complex secrets of his workshop to this day. However, his master has never truly attributed the value of a human being to him; the reason Aubert endures all that torment in his master's workshop is his heroic loyalty to the beautiful Gérande, whom he secretly adores. Throughout all the madness, he represents good sense, striving to explain facts through gear wear and logic rather than supernatural obsessions.
The only thing known about his past is that he has remained loyal to Master Zacharius since his youth, despite his profession and such peculiar personality. He has learned much from his craft genius but has not fallen into that dark arrogance within him. In Geneva, he managed to attract Gérande's attention through his slow and respectful demeanor.
A clean-faced, well-built, young Genevan apprentice. It is obvious from his gaze that he has remained sleepless on exhausted nights; he has an honest and honorable manner.
