Overview

Inductor is Gluthoric’s loyal Iron Defender companion—a mechanical construct forged at the Last Ore Forge on Sphinx Island. Created from the final ore extracted from the island’s depleted mines and crafted with Master Ferros’ guidance, Inductor represents both Gluthoric’s craftsmanship and his connection to Sphinx Island’s heritage. The construct serves as protector, ally, and symbol of the island’s transition from mining to pure artifice.
