The Haydonites provided Shadow Devices to Admiral Rick Hunter's Robotech Expeditionary Force to assist them in the war against the Invid. All the technical details for this Shadow technology was given through the android Janice Em on the condition that the secrecy of the Haydonites' involvement was maintained. Shadow devices provided an excellent advantage to the Robotech forces as they were invisible to the Invid sensors. Ultimately, the Third Robotech War ended with the Earth freed after the Regess departed the planet in peace.
