Not the time when we gave up food, while we were starving?
I really liked the update where the pregnant refugee traveled through the badlands to reach the People, and thought Valleyhome looked like paradise.
Also, in addition to the "one of" thing, i'll say that while the drought situation was a
prouder moment, and a better representation of whats really the core best thing about the People (the selflessness and generosity even when having little...something thats become a bit strained now that we're so rich, hoenstly...), it was so because of selflessness, not so much from accomplishment and badassery. The cholera cure might honestly be the single most concentrated moment of achievement and badassery the People have; our military victories are mostly through better tech or numbers (and the one exception i can think of is the "fuck nomads" bit, and that was more a statement of tenacity than of skill, and probably would have been a Pyrrhic victory if not for iron), Sacred Warding took much longer and was a Hero's work, both sacred forests took generations... defeating Cholera, on the other hand? The work of less than a generation, without a hero, in an automatic kicked (as in "so central to who the people are that they didn't even consider whether to do so, or whether to go all in) response action that saw random People volunteering to die terrible to the new demons plaguing the People--and then gave the results of those sacrifices out to all; iirc the choice was specifically
making people take the information even if they didn't want it. That wasn't entirely selfless (because that cure was not perfect, and so having others know it helps us), but its still liekly the most badass thing we've done, accounting for things like "winning handily because of iron isn't exactly super badass, compared to winning handily while at a disadvantage"
