I'm starting to come around to ambassadorship.
Really, I just want to know who we will stop getting to see with the partial cast reset. If it means less of Meizhen or Su Ling, I'm against it. Sadly, it probably means less Suyin but I have accepted that and we already have the cyan breakthrough potion hook to spur further interactions.
Based on what Yrsillar said so far I'm PRETTY sure we'd still be physically based in the Sect for the next couple of years, but with obligatory expeditions beyond the Wall and to set up our fief claims.
It'd be a pretty long while before our new fief could be considered safe for our still mostly mortal household to move into unless its into a fortified bunker they can't leave.
Our friends should still be our friends, but the Sect(i.e. the Sect Nosy Aunts Club and Elders) would be gradually distancing from us as we formally align with the Cai.
The Young Emerald Seas Nobles should if anything be MORE aggressive in forming contacts with us if it gets out that we got a prime piece of meat in our teeth, because they want a bite.
So of our social circle:
-Liao Zhu - War heating up and he's aiming at Core Sect, likely see him less simply because we don't share a command.
-Meizhen - She was going to petition her family to be emissary to Cai Renxiang's court, so likely more scenes.
-Suyin - Less time probing Sect places with her for goodies(though there may be some kind of push to go nuts on the map before we're done). However, Bao Qingling is connected to us through Meizhen and Bao Qian(who may not leave even if hit with a stick if he hears about the business opportunities), so I expect little change until we officially move into our fief.
-Su Ling - There IS that Gan ship being floated around, but as far as I can tell, Su Ling has no particular loyalties to the Sect except as a means of getting stronger, and is more invested into looking out for the little folk. Recruitable I suspect, assuming we make the effort.
