Enter the God Zone Part 4

The Occult Master has been chased out of the OUU, but things have gone south as the Occult Leader has gained control of the AUU Interdimensional Portal, and has blocked the heroes' access to the AUU to stop him for good, banishing the Heroes Act and the Anti-Villain Squad in the process. With his immunity to reality-warping powers, even Saldaron and the Reality Stone are of no use to this. However, there is still a slim chance that they can go back and fix everything. They deduce that, while they have little knowledge of how the Yatorans created the Intrdimensional Portal, they remember how the Lodgers got there: a black hole portal. However, the black hole portals' destinations are random, so just flying in hoping it would take them there is not a smart idea. But how will our heroes be able to create such an advanced device?
