As the world ponders the fate of the Flash, a bizarre planet appears to be moving closer to Earth. This planet is in reality, a projection from the 7th dimension, a focal point through the Star Sapphire is siphoning off Earth's oxygen by destroying the planet's plant life. As the doctors began to collapse for lack of breath, she astonishes them in her astral form by lighting a cigarette and shattering the case in which the Flash and Dr. Flura are held. She explains that, by her calculations, The Flash has two minutes of life left, a fact she announces to the astral Flash on her homeworld. When his physical body dies, so will the astral one. She then challenges the Flash to a race, one in which he attempts to destroy the machine siphoning the oxygen from his world and she races to speed it up. He has only two minutes.

    As the two speed across the bizarre landscape of the Sapphire world, the mad queen throws a variety of obstacles in the path of the speeding hero. Reaching the device with only seconds left, the Flash pours in a last bit of speed and as Dr. Flura observes from a distance, the oxygen-sapping device explodes presumably destroying both the Flash and Star Sapphire. Weeping for her loss, Flura is surprised when a smiling Flash races towards her. The Star Sapphire, he explains, has made a fatal error in calculations. Time as they know it on Earth is in no way related to time as it passes in the 7th dimension. What seemed like imminent demise on his own world was actually hours on the Star Sapphire planet. Rather than determine the fate of their tormentor, the two quickly board the object that brought them there and return to find themselves once more in their normal bodies and the populace gratefully gulping in the precious oxygen. The Star Sapphire was no where to be seen (All-Flash Comics #32).

         Nonetheless, the world had not heard the last of the Star Sapphire.  A few months later, Jay Garrick settled into a restful sleep after a day of battling minor criminals. When he awoke, he noticed the man who tended the local newsstand was not on his job. Strolling further along, he encounters a group of women who seem astonished to see him. He is equally astonished when they seem most amazed at his gender. Ducking into an alley, he quickly changes to the Flash to elude the mob of women. Vibrating to keep himself invisible, he listens to their chatter and learns that none of them have seen a man all day. Reflecting, the Flash realizes that he also has seen no men. Slipping away, the Flash wonders if he is not indeed the last man on Earth. Meanwhile back in the park, the women notice a falling star heading straight for them. As it draws closer, it assumes a female shape, one the women recognize as the Star Sapphire. She declares she has dispatched the men of the world to the 6th dimension and come to claim both the Earth and it's female populace for her own. The women resist and attack the would-be conqueror, only to be easily repelled. One of them escapes and finds the Flash, warning him of the Star Sapphire's arrival. When the Flash races to the scene, he finds Star Sapphire rapidly rolling the women in mid-air, causing them to disintegrate. By racing counter-clockwise to the women's rotation,  he slows them down to normal. The Star Sapphire threatens the hero but as the Flash nabs her, they both disappear. The Mistress of the Seventh Dimension appears quickly, gloating that she has shifted the Flash to her home on the 7th dimensional Star Sapphire planet. She can rapidly return, she claims. He cannot. She then destroys part of the Keystone City skyline to emphasize that further resistance would prove not only futile, but fatal.

        However, as she had in the past, the rogue queen had underestimated the Flash. While lacking the direct route, he wound his way through the 6th dimension, retrieving Earth's male populace and through the 4th dimension of time, returning the men to the instant after they disappeared. Their arrival corrected their own disappearance and the Star Sapphire then never arrived. Jay Garrick was returned to his home and the end of a good night's rest, the loop in time rapidly becoming a fading memory (Comic Cavalcade #29).

    Whether the Star Sapphire ever escaped or is still alive remains to be seen.
