Synopsis for "The Terror Beyond Twilight!"
General Zod and his allies toss Supergirl into the disintegration pit and leave, but Supergirl barely saves herself by reviving in time and digging her fingers into the side of the pit's wall. She drags herself out of the pit and collapses.
Superman and Charlie Kweskill penetrate various lower (or higher) levels of the Phantom Zone, encountering an alternating yellow-and-red Vortex Sun which Superman had once seen while racing with The Flash, battling monsters, and encountering weird "Priestesses of the Crimson Sun." Finally, they meet Thul-Kar, a Kryptonian wizard. Thul-Kar tells them he believed Jor-El's prophecy of Krypton's doom and entered the Phantom Zone by magic. While there, he discovered the truth: that the Zone and all its levels are manifested as the interface between the Earth-One dimension and that of a sentient universe called Aethyr. Only by entering Aethyr's realm can they escape back to Earth, and that is dangerous indeed. Charlie and Superman bid farewell to Thul-Kar and enter the portal between the last Zone level and Aethyr, who strikes back with an energy-burst that knocks out the two invaders.
On Earth, while Supergirl recovers, Zod and his three chosen allies are building a giant Phantom Zone Projector, powered by Green Lantern's power battery power battery, to project the Earth itself into the Phantom Zone.
