New Gods#1(1971)

After a battle when the Old Gods died, a release of indescribable power tore the Old Gods' home asunder, splitting it into two molten bodies that drifted through the cosmos. An age later, Lightray welcomes Orion of the New Gods, wielder of the Astro-Force, back to New Genesis, after he was summoned for a mission by High-Father, wielder of the Life-Equation through his Wonder-Staff. High-Father escorts Orion to the wall that is their link to the Source. Before the Source delivers its message, Metron arrives. The Source delivers its message, "Orion to Apokolips--Then to Earth--Then to War", which Orion accepts as a mission. As Orion leaves for Apokolips, Metron reveals to High-Father that he knows that Orion is Darkseid's son. High-Father pleads with Metron to keep that secret. Orion arrives at the planet Apokolips. Para-Demons attack Orion, but he escapes them using the Astro-Force. Orion searches for Darkseid, but only finds a Mass-Director Unit transmitting Darkseid's orders to Apokolips. Kalibak, guarding Apokolips, attacks Orion, but Metron appears and stops him with an energy barrier. Metron reveals to Orion that Darkseid is already on Earth, searching for the secret of the Anti-Life Equation, which a human holds. Four humans were already brought to Apokolips to be probed. Metron leaves, freeing Kalibak. Orion frees the captive humans and escapes to Earth alongside them through a boom tube. Now on Earth, Orion declares to Darkseid that the battle begins. Darkseid answers and concurs.
