They encountered Su'en.
The entire Heart Stealer expedition fleet was corrupted, and the massive fleet became Su'en's slaves, stationed in the Distant Realm.
The Heart Stealer fleet of Su'en arrived during the Dark Era, approximately over a thousand years ago. Together with Su'en, they descended upon the Terra Star System. Su'en was an Upper Position from an unknown star system; after corrupting and eroding its original star system, this powerful ancient being sensed the force of Divine Terra, then led the enslaved Heart Stealer fleet into the Bizarre Realm.
By then the Fallen Mother Goddess had already arrived, and the entire Garden Planet had fallen.
Thus, the Heart Stealer of Su'en gained an easy win by directly occupying the Garden Planet and transforming the twelve satellites into his celestial stronghold.
The nameless tried to recapture this planet once.
