Just as Helen's energy beam was about to strike Thor, a faintly glowing magical barrier suddenly appeared in front of him. Frigga slowly descended from midair.
Little Helen was incredibly inconspicuous beneath that beam. In the vast expanse of space, any tiny fragment of a celestial body was far larger than Helen. If one did not look closely, one might have mistaken her for a speck of cosmic dust.
