Headscratchers / Aura Battler Dunbine

• Part of the problem the "surface" world faces in the latter half of the show is the sheer overpoweredness of Aura Battlers compared to our own weapons of war, as for unexplained reasons Aura Power is ten times more potent on Earth than it is in Byston Well. Which just calls into question why, if Aura Power is so incredible, we Earth Humans didn't discover and utilize it first?
  • Perhaps it's a similar situation as what happened in the short story The Road Not Taken as detailed here.
