Retreat
The Gaia Civilization expanded and lived in the void outside of planet Gaia during their most prosperous era. Remnants of their interstellar age could ever be observed in the high heavens above, day and night.
The debris ring orbiting planet Gaia was none other than their ruins.
After Duna received Leon's answer, she realized this.
"If these mutants came from the orbiting debris in the void, how did they get here? And of all places, hide underground?" Duna asked.
Undoubtedly, she believed falling at high speed from the void would kill any life the debris carried with them.
Leon shook his head and said helplessly, "I don't know. We can only find out in the future whether my speculation is true or not."
"I suppose." Duna shrugged.
Shortly after, Leon and Duna passed through the short passageway they came from and returned to the Heart of Spring Chamber.
