[@CaptainManbeard] Terra was on a planet called Khulthak when her powers activated, saving her from death by falling when she was six. It's kind of a pivotal part of the story.

I haven't read the Invincible comics, only watched the Prime series, lol. And I wasn't referring to Terra's powers activating, but America's. Meaning when America's powers were new and she was leaving Traveler Auras on people until she learned greater control of her powers. The Auras are sort of like cosmic energy that was leaking from America until her control of her powers became less sloppy. It is these Auras that Ultron and the Sentinels are scanning for in various universes to target Traveler Candidates.
