"With the wonders of machinistry in their hands, a trained army of commoners could prove as effective as any company of knights."
The eldest son of House Haillenarte, as a child Stephanivien often indulged his obsession with machinery by visiting the manufactory, his ready mind quickly absorbing whatever scraps of knowledge the engineers in his family's employ would throw his way. His frequent association with lowborn artisans—unheard of amongst the haughty nobility of Ishgard—likely contributed to Stephanivien's unusually enlightened attitude.
After coming of age and unofficially assuming the position of manufactory chief, Stephanivien actively sought the cooperation of organizations outside of Ishgard, drafting a contract for technological exchange with Jessie Jaye, the deputy president of Garlond Ironworks, and hiring a Limsa Lominsan to instruct his machinists in marksmanship. He is also a staunch believer in encouraging the martial independence of Ishgard's commoners, reasoning that every machinist recruit can only strengthen the city-state's defenses.
