Overview

Master Ferros was a revered elder of the Magnetron Artificer Guild and one of the foremost experts in magnetic technology in the known world. As a master artisan specializing in electromagnetic applications, he mentored many apprentices—including Gluthoric—and contributed groundbreaking innovations to the guild’s collective knowledge. Three years ago, Master Ferros vanished without a trace, sparking an investigation that uncovered evidence of the mysterious “Project Lodestone” conspiracy infiltrating the guild.
