Excellent update, Yrsillar!
I want to say that Reverie is more challenging to Ling Qi, which I like, but that's not fully accurate. Or it's misleadingly framed. Fantasia appears to engage with inspiration and art in a way that Ling Qi only literally just now managed to brush her finger tips against. That's also challenging.
But I do think Reverie is a more direct confrontation with limitations of Ling Qi's as they currently stand and have been identified in the narrative. There's arguably more material, more ready to work with. And it's things we do want her to learn, I think.
Ling Qi has been Isolated from a lot owing to her upbringing, self-directed and otherwise. Comfort topping the list, even making it on to her list of dangers. I'd like it if Ling Qi could confront her discomfort and see past it to the less sinister motivations underpinning simple revelry. I don't mean to "get over" her traumas or anything, that would be ridiculous, but I do think she can take the plunge to see around them now, to see more than just dangers. Especially with Sixiang as a trusted guide. And it'll help their friendship if Ling Qi isn't existentially paralyzed by the prospect of exposure to things that make up a decent chunk of Sixiang's existence; it's also about seeing the full being of Sixiang and not rejecting it.
[X] Dive unto the dim, warm halls, where bodies are packed, where revelry abounds, where the halls are scented with food and sweat and life. Ignore the crawling shadows, the webs spun in corners, the strained smiles. Witness Reverie
Leaning towards this one for the abovementioned reasons.
