Safe:
Renxiang
GG
LQ
Biyu + Qingge
Meizhen
Fefe (the question being whether she also stays at Sect, or immediately leaves to follow Meizhen)
Maybe:
Li Suyin (strong sect route, but will have more interesting rare things and free time away from being overworked by Sect. Likely to stay, but might leave. Especially if Qingling is going too. Even if she returns to the Sect afterwards, the opportunity is pretty juicy)
Su Ling (Sect is strong, but I'm sure we could pitch her on Renxiang's Justice. She has a heart for the commoner like nobody in the current circle has. She'd make it better)
Bao Qingling (following our group would pursue personal goal of Duchess' Attention and Bao clan interest in new trade)
Bao Qian (following our group would pursue personal goal of new prospects and Bao clan interest in new trade)
Wang Chao (Scion of relevant Border Count, might be regular visitor might drop by rarely)
Xuan Shi (by all accounts should be a definite yes, but because he is who he is he might just choose to stay home)
Not happening:
Ruan Shen and Bian Ya, who won't forget we saved his life.
Jiao and Xin
ThunderPupper gal and the concert in the sky
Alingge (well. Maybe. But I doubt it)
Guan Zhi
Ji Rong and Sun Liling
Hypothetical Imperial Contacts From Someplace Relevant
Happy Sect
Luo boy (I would assume, but he could probably get in.)
people that are already gone:
Broken Fields Group (Han Jian, Han Fang, Fan Who)
Ma Sisters
Xiulan (who might be able to show up where we are anyway)
Liao Zhu (in a coma and dying)
I duno. The only part of our social group tied inextricably to Sect is Music Club. Everything else has a shot of staying relevant, or a personal choice on the other person's part. Everybody else is getting picked up and yeeted to !notRussia with us, lol
