Im 👀 at your Mondstadt having an underground area and I just want to bring up this idea in a fanfic I read (Windwheel Aster: Adored by the wind) where Mondstadt has secret underground passageway between them and Liyue for emergency use. Now im combining those ideas in my head of underground passageways beneath Old Mondstadt. Like some sort of dark souls crypt for those who perished (since its Really Hard to do a burial in the snow). You know how the wind brings Mondstadter's souldls home? Yeah what if thats not just a Venti thing but also existed during the time of Decarabian. (I can tie this into Istaroth but thats a whole nother paragraph)

DON't MIND ME HAVING SpeNT most of hte day reading that fic ahem

Crypts under Mondstadt...oh I love that idea it fits in mood-wise with the Actual Dead Guy under the statue, giving Mondstadt and ameno all the more ties to death and souls and imprisonment + yeah how do you deal with bodies when the ground is frozen hard and the city is micromanaged by the god. Why, if the bodies are getting in the way, why not remove them, help the souls pass on, and place the bodies neat and orderly filed away. Away from the people so they can focus on life instead of death, but each passed person can still be easily found in case they're needed. Besides, crypts are often under a church and Mondstadt is the nation most known for having a church....maybe not under Mondstadt's currentday church, but the people did use to 'bow' around the tall tower which houses a god....

But also........those Istaroth ties? 👀👀👀
