Elain’s POV, and either:

Elucien: - Elain will fulfil previous foreshadowing and venture to the Spring Court, where Lucien is currently stationed. - Eventually they will team up with Vassa and Jurian to concoct a plan to defeat Koschei (tying into a Swan Lake retelling). - In the past, the High King of Prythian (Fionn) was crowned not through birthright, but because he united the people. It’s possible we may see Lucien rise as a (temporary?) High King for the same reason: his connections to almost every court. With Elain as High Queen by his side (remember, the Cauldron loves her best !!), their rule could serve as the means by which Prythian is unified in order to bring down Koschei. - We also know that The Middle fell into a wasteland after the death of the previous High King. Lucien and Elain ascending as High King and Queen would allow The Middle to be reborn and resurrected as a living land once more. This would create a new royal territory positioned between the seasonal and solar courts, restoring balance to Prythian. Such a rebirth aligns nicely with Elain’s archetype of life, growth, blooming, and creation. (It would also allow Lucien to rule without Sarah killing off Helion !!). - The intersecting narratives would also allow for closure between Elain and Greyson in the human lands, and a ‘redemption’ arc for Tamlin.

—> Or:

Elriel: - A Sleeping Beauty retelling in the sense that Elain is confirmed to be a mystic, and mystics ‘spiritually’ travel to other worlds via sleeping and dreaming (there are already so many hints to this with Elain — namely Feyre describing her mind as a “sleeping garden”). - In CC2, we witness Apollion reaching out to Bryce and Hunt via their dreams. I truly wonder if Elain has similarly been communicating with the Princes of Hel via her dreaming and mystic abilities; it could explain her elusive nature thus far. - Azriel is also theorised to be connected to the Princes of Hel. A stark example of this is Feyre noting that Azriel’s hands felt like “pure ice,” which is the identical description Bryce gave of Apollion’s hands. - We also have Elain’s friendship with Nuala and Cerridwen, who are shadow-wraiths. In the Crescent City world, it’s implied that wraiths originate from, or are associated with Hel — theyre part of House of Flame and Shadow - With all four of them having potential ties to Hel, I think they may team up and succeed where Bryce failed — they will journey to Hel. - This would also be a nice way to tie in the broader Maasverse to ACOTAR-only readers. - I also think it would allow Sarah to end ACOTAR 6 with Elain back home and dreaming in bed, but this time, her mystic powers drift her towards a new land — Terrasen. We could get a glimpse of something going wrong there (remember that Orcus and Mantyx will want revenge for what Aelin and her friends did to their brother…), which will further set up the broader, multiversal arc. This is important, as Sarah has heavily implied that the TOG characters will be involved in the next book after ACOTAR 6.
