The Ghen subsequently blame the crew of the Da Vinci for destroying Sunstar and Titan and invading Mars, and use human figureheads under their control like Commander Braxton to try to trick them into returning to Earth for disciplinary action. The Da Vinci easily realize their deception and continue anyway, with Relay Commander Reynolds (their only contact due to the interstellar communications blackout) informing them that the starship Goliath is dry-docked on Moonbase 12. After returning from the Moon, they wire Boxhead into the ship's communication systems to send a transmission directly to Earth, only to find Reynolds has also fallen under Xylan's control. After Xylan's transmission is intercepted by Wilson, now leading an underground resistance against the Ghen, they discover the Ghen are using the implants to sedate everyone on Earth. They then head for the implant manufacturing plant in Australia to liberate the sedated humans.
