She is beautiful
I just recalled a quote from the first novel where Kratos pondered whether Athena would vanish if Ares destroyed all the sites of her cult. Perhaps people simply came to believe in Faye, and that is precisely why she was perceived as a goddess? Especially considering there are plenty of magical creatures there who aren't gods at all...
In other words, for the ordinary mortals of Midgard whom she protected from the tyranny of Odin and Thor, she became their only hope. She was revered, she was extolled, and she was prayed to. The Jötnar are a powerful race by nature, but they never demanded worship. Faye, however, went beyond the boundaries of her people. She led humanity. For the world of *The Everywhen* (which, by all accounts, manifests the very 'concepts' born of human myths and belief), Faye could have materialized precisely as a fully-fledged protector goddess, because that is exactly how Midgard remembered her.
So... I doubt Magni, Modi, or Heimdall will be there. Heimdall's death was a point of no return for Kratos, proof that some conflicts cannot be resolved peacefully. His purpose and character were 100% fulfilled. Furthermore, Magni and Modi were never worshiped, and Heimdall's personality likely stripped people—and the Aesir themselves—of any desire to pray to him anyway. They just aren't needed *narratively*, as their arcs and motives were already explored to the exact extent required for the protagonist's journey.
And just as Odin said in *Ragnarök*, Kratos never experienced true worship when he was the God of War, which is precisely why he didn't end up in *The Everywhen*. Kratos was more of a general than a god:
> 'And what kind of god is that, Kratos? What do you even know of godhood? In your lifetimes, has anyone ever worshiped you? Ever prayed to you? Can you even imagine that kind of love? No!'
Odin isn't talking about power. Not about magic. Not about lineage. He is talking about faith.
Faye’s magical power is a consequence of her race, not her divinity. Jotnar are inherently woven from magic. However, if "raw magic" were the sole deciding factor, absolutely every single giant would have made it into the Everywhen—including some nameless Grua whom Thor killed in a drunken brawl. They all possessed an ocean of magic, but either their concepts were erased, or they themselves are creations made of magic. Though if he does show up, it would be hilarious.Maybe it's because raw magic is the "fuel," while the faith of mortals is the "mold" that this fuel takes?Odin had more "raw magic" than anyone else in the Nine Realms. He literally crafted this world from the flesh of Ymir. Why would a being with infinite magical power peer into the rift and interrogate Kratos about the worship and love of mortals?For two generations of games now, the studio has been moving away from the concept of "a god is just a strong superhero." They are writing a drama about metaphysics and responsibility. Reducing the nature of a higher dimension to "who has the bigger magic battery" is simply too primitive for the current GoW writing
