Glassteel: Made by the artificers and craftsmen in an alchemical process requiring extensive knowledge of both metallurgy and glassblowing, glassteel combines strength beyond iron with the transparency of glass. Mostly used as a building material in fantastic castles, glassteel can also be fashioned into weapons and armor. Glassteel is stronger and lighter than iron—but it’s fantastically expensive.
