About category 7 Gate

So I think that category 6 gate isn't the last one. It's only to give u divine rank. But we know that gods are beyond rank or classes and considering 7 as a special number we can assume that there's a category 7 Gate as well.

And the trial for this gate's seed is the Doom War. To either stop it or let it happen. Also, the reason why Asterion is letting divine Lineage live is because only people with divine Lineage can enter the category 7 nightmare since they will be taking the place of the gods in the war. As for sunny, he will replace the weaver probably but we don't know about his shadow god's Lineage so not sure about his place in the nightmare
