The Gate of Creation was the entrance to a wormhole.
Over the years, each side disagreed as to what was really in the wormhole. This lead to a war known as the Eternal Dogfight. In 2015, the Dogfight came to Earth. Alice Obiefune volunteered to go through the Gate. Her grief over her mother's death immunised her from the extraordinary beauty which had captivated the previous astronauts. She returned through the Gate and told what she had found, thus ending the war. (COMIC: The Eternal Dogfight, The Infinite Astronaut)
