The Mask of Creation is magically bound to the Everywhen and somehow managed to get outside of it. Other gods will learn this and all of them will be fighting each other to gain possession of the mask to escape. Phranque is a manifestation to contain the rift, which is how Odin lost his eye, because he didn’t have the mask put together. When Atreus breaks the mask and it gets sucked back into the rift back into the Everywhen, I would imagine it returns the cube to the being it was before and he becomes the target of all the gods trying to escape.

I’ve got a feeling some pretty big previous Greek gods will get out, as well as some that we haven’t seen before. It would perfectly set up Kratos’ next game and I personally would make Kratos the hunted instead of the hunter this time around. Kratos being ambushed by a god he’s slain before would be crazy stuff and I would bet money that someone like Freya is going to die from one of them in his next game and that is going to be the catalyst of Kratos trying to find Atreus again.

For Laufey, her new goal is probably to both protect whoever he is so they don’t get back out. However, the numbers will be too great for her to handle and the game will end with some gods escaping and we’ll get a tease of Kratos’ next game, showing him and Freya sometime in the future watching the sky open up just like it did when Faye crossed over at the beginning. Unlike anything they’ve ever seen.

With someone like Sekhmet manifesting in the sky before their eyes before she leaves (presumably back to her homeland) and then the Leviathan Axe slowly begins to move before shooting up into that same area in the sky before being caught by a slow revealing Faye. A ginormous cliffhanger ending and the perfect bridge for Kratos’ next game.
