Giancarlo is the manager of the Horizon Cave station and a subordinate to Duke Henry Knowles. He also serves as an auctioneer when the supposed Exile artifact is opened for bidding at the black market. He takes the artifact, auctioned at 50 billion Claudia, to Maestro Delphine Eraclea but discovers it to be fake. Delphine gives him a Guild ring as a "reward", but the ring's power kills him by turning him into dust.
