Perhaps Rebecca has been underestimating Wen; she hadn't expected her to be so... globally minded?
Or maybe it's Rebecca who's been making too many assumptions. She pattern-matched the Three Jades Sect to the PRT based on their stated ideals and state sponsorship, and so assumed they were in the upper classes of power, but that's not a given. Even if they are the big fish locally, the nation itself might be second-tier on the world stage; if you dropped someone randomly on Earth Bet, they're as likely to end up in India as in North America. In Bet's India you'd still hear about the PRT on the news, but here communications are probably more limited, so the dominant cultural presence of the Three Jades Sect is expected.
Except Wen said Cloudsoar City hosts the largest gathering of powerful sects in this region, so the Three Jades Kingdom is a major player... no, a nation can be an international center or historical gathering place without being powerful in the moment. And Rebecca hasn't confirmed there aren't stronger sects within the kingdom itself, though that would beg the question why the Three Jades still controls and privileges itself the land's natural resources instead of being strong-armed by more powerful sect, or overthrown outright.
There's also the question why another country with stronger cultivators haven't invaded, if the local sect is weak. Unless the jades aren't that valuable on the world stage, enough to build a country on but not enough to attract wolves. Still, historical empires on Earth have claimed colonies for less. Though there was an implication—
"Are the strongest sects usually not affiliated with a nation?"
She rubs her chin.
"No, let's not go down that rabbit hole now. I don't have a good model of the power structures in this world. The reasoning you gave would have been obvious without saying, to a local? Local cultivator, I mean."
She might need to acquire reading material on sects and world politics.
