Cloudverse

Sixty-five million years ago, Pandora and the Phrenosans inadvertently broke the Multiverse, releasing billions of universes from an orderly, well-connected structure. Since then, these universes have been mostly cut off, progressing apart, not only from each other but also from the assistance of the Ancient Ones and the Timeless Ones, the two old civilizations charged with installing space-time technology to link universes together.

Now, something has changed. Not only have the gateways to the empires of the Ancient Ones and the Timeless Ones reopened, but somebody is perturbing the events that happened when Pandora and the Phrenosans shattered space-time. Four Phrenosan Higgs Devices, presumed lost forever, have returned, and the Ancient Ones and Timeless Ones are in a race to find Pandora's Box, which holds open the link between the old Multiverse and the new Cloudverse of billions of scattered galaxies.

When Zurn, the higher-dimensional being who seems to have been around forever, learns of these developments, he springs into action, sending his emissaries, Zeus and Apollo, to dispatch the Science Club Kids to the Drahcirian space transport, Nomad, where they learn that they must turn off Pandora's Box and conceal it. To help them in their quest, Zurn summons the beetle-like Harbingers of Dûm, the manufacturers of the space-warp modulators the kids used to travel to Azuna during their first adventure.

Things go chaotic when Prometheus and his dim-witted brother, Epimetheus, disable Nomad's computer and attempt to attack the Harbinger home planet. Zurn splits his team into two groups that meet again at the Alpha and Omega, the warehouse at the beginning and the end of the universe. There, they battle Ancient Ones, Timeless Ones, and an indoor hurricane in a fight to reach the End of Time and save the Cloudverse.
