Sare's references to the order in her posts are generally frustrated?? She wants them to be gunning for DEs that escaped the battle (in particular the one that killed Kayla) and she's refusing to accept that that task really falls to aurors now.
When she talks about it in posts she accuses the Order of stagnating in general, and that's me laying the foundations for a very long off (we're talking possibly more than a year of playtime) personal plot of Sare losing faith in other order members if she can't recruit their help and chasing after the DE herself.
On another note I once remember talking to Hels about Briony being willing to be an on call healer for them should they ever have cause to bring a person in for interrogation or smth. She discovered the existence of the Order in the aftermath of the BoH when
@Kendrick Silverman and
@Jocasta Silverman finally told her they were members. She's not keen to join herself but like I said she'd offer her services.
