- Both Snezhnaya and Khaenri'ah shared the same OST and sequence in Travail
- Hoyo uses Dainsleif's face and splash art for some Traveler quests, which is always and only related to Khaenri'ah since 1.3
- Our twin said "we will meet at this journey's end, once the dust has settled" 5 years ago
- Our twin said "we will begin anew at the end of your journey" in 5.7 and that emphasized once again our journey is through the 7 nations to reach "the journey's end". So, we'll meet our twin at the end of our journey, but in the Travail the Khaenri'ah Chapter is before our journey's end
- Venti, in the 6.4 event, said Snezhnaya is the last stop of our journey
- in 4.7 they completed the Loom of Fate and in 5.7 they used it and they were technically ready to host new Khaenri'ah
- This is the Teyvat Chapter Storyline, and they implied what comes next are the lands beyond Teyvat and distant worlds, and Khaenri'ah is part of the Teyvat Chapter.
I think we have a lot of basis on this, I wouldn't call it "rushed/out of nowhere"
per chi se lo stesse chiedendo, Snezhnaya e Khaenri'ah condividono la stessa OST nel Travail. Ci sono altrettante varie e valide ragioni dietro, in caso dopo manderò tali motivazioni
