Silas is a man of precise features and graying hair, often found wearing a leather apron over his scale mail. His fingers are stained a permanent deep indigo from chemical exposure. He carries a variety of bubbling vials strapped to a heavy bandolier across his chest.

Meticulous and somewhat clinical, Silas views the world as a complex machine that simply needs regular maintenance. He is patient but has no tolerance for sloppy craftsmanship or people who rush through important tasks.

Silas spent most of his adulthood in the Crystallographers Guild, mastering the art of infusing molten glass with alchemical reagents. His life was one of orderly production and quiet study until a rival guild sabotaged his laboratory. The explosion did not just destroy his life's work, it revealed that his master had been using illegal soul-trapping techniques to empower their creations. Silas chose to report the guild to the High Arbiters, turning himself into an outcast for breaking the guild's code of silence. He now travels as a freelance tinkerer and alchemist, seeking to reclaim the materials stolen from his shop and to ensure that technology is used for advancement rather than exploitation. His skills are sharp, honed by years of workshop labor, but his heart remains guarded by the heavy iron of his experiences.
