Syvestro represents the ideal blend of alchemist and soldier. His demeanor is serious, and he does not succumb to fanciful obsessions over every new alchemical discovery, preferring to keep his work pragmatic and focused on advances in military alchemy. Whenever possible, he hones his battlefield capabilities, pushing himself to improve his martial skill through practice bouts with other soldiers, physical trials, and simulated combat between actual engagements. While others rest, he tests his mind by studying and refining formulae long into the night by the light of an alchemical lantern.
