so i know we as a fandom (including myself) have a tendency to place Churki as the wise elder voice of reason
because yeah she is often the more sensible of the dragon gang! she's less likely to go haring off after violence, more inclined towards diplomacy, often with a different view of human-dragon relations than our mostly-European cast (for better or ill)
you have to remember two things
while she is still older than Tem, Iskerkie, et al., that's mostly because they are basically still baby. Tem's the oldest and he's like, what, five years old by the Inca adventure? Six? Being in her twenties, Churki is admittedly like double their age, but that's still young for a species that can get into their 200s.
yes she's a veteran. but then you remember that Incans put young dragons in the army because they see it as a way to get their youthful fighting spirits out of their system till tey mature and are ready to settle down and focus on sensible things, like playing the Sims with supervising their human allyu
with all this in mind, I think the Churki + Aerial corps gang is less "mature retired general taking twenty something soldiers under her wing"
and more "rich 22 year old who just graduated and can't quite decide what job she wants, so decides to go backpacking across Europe after the cute situationship she's crushing on (platonically, interspecies), while said crush keeps trying and failing to ditch her. meanwhile, a gaggle of 12-15 year olds are trailing behind her, listening to her every piece of relationship advice like it's gospel"
