SPOILERS FOR EVERY BOOK IS FAIR GAME, my sister and I have had thoughts. I’m an audiobook girlie so sorry if they’re spelled wrong, I’m not looking them all up lol.
1.) Aelin opened the doors and let the gods out. She did this when Feyre was pregnant, and we know the stories are all happening at the same time.
When Nesta and Cassian were in the prison while Feyre was pregnant, the cells opened on their own. This could mean the gods were really just locked in the prison and leads to a solid connection of Prythian and Aelin’s world. The god of truth then could be the bone carver, which solidifies the worlds together more.
2.) we have had a theory that Feyre’s mom was a human/fae slave descendent. Potentially Celine’s as this would explain why the sisters are all showing starborn signs. The asteri themselves say it only takes a couple generations of breeding to round the ears and get rid of wings.
We also think that Celine died from the Asteri’s first tries at the parasite that they then perfected in Midguard. If you don’t make the drop, the parasite will bleed you fry and eventually kill you which would make more sense than dying of old age.
3.) we also theorize that the valg are just asteri that didn’t leave their planet. Which would connect tog and acotar again if you think of how valg-y the king of hybern seems. Also the acknowledgment of witches existing there as well. That Keir could be a valg prince or general too.
Would love to discuss with everyone 😂
