A Small Post from Super Dimension Cavalry Southern Cross

I remember watching this old anime back in early 2016, it was the second series used for Robotech called "The Masters Saga". By the show itself was about mankind leaving the Solar System after the Earth was unhabitable after an massive nuclear attack and started the colonization of other planets and one of the farthest colonies is located on the terraformed planet, Glorie. The powerful army of the Southern Cross protects the colonists there from any unknown dangers and threats. However, unknown to the humans live there, Glorie is also the ancestral home of the Zor, a highly advanced race of nomadic humanoid aliens who have returned to reclaim their world but the humans refused to do so which led to their war with the Zor.
