The previous homeworld of the Invid race, Optera was devastated by the Robotech Masters. The Invid Regess abandoned the ravaged planet when the Flower of Life was discovered to be thriving on Earth.
However, the Invid Regent stubbornly continued to occupy Optera until his death in battle with the Robotech Expeditionary Force. The Regess would later ominously reveal that the Invid had previously fled another homeworld before Optera to escape the "Children of the Shadow."

The Invid under the control of the Regess leave Optera for Earth.

The desolate surface of Optera.
