Oh yeah, I thought some of the stuff here reminded me of the Eastern stuff I've seen. [Particularly the east street of Crossbell...but mm let's not mention that city by name right now. Rean's in a good mood. ] Maybe this is Teyvat's version of the East.

[Rean was going into full nerd mode and frankly, it was endearing to see. He leans forward, resting his chin in his hand as he listens to him]

Haha, I wouldn't stop you if you did! I'll even make sure you get some sleep each night like you did for me. It sounds like we'll have some downtime before we'll be needed, so you might as well enjoy yourself.
