I've seen nearly no amount of discussion on this, and I wanted to bring it a little more into the light to hopefully get an official answer, but at the very least, a better idea on the topic. When Summerset released, we got a ton of new information about Altmer and their culture, the way their society operates, and so on. But of all their societal features, we never got any information on whether the ideas of Praxis and Alaxon were also shared by the altmer in Auridon.
Auridon is the geographical buffer to Summerset, something that is explicitly mentioned in lore as a way to keep outsiders away from the sanctity of the Isles' mainland. Auridon receives the brunt of everything from foreigners to pirates, plagues, and invasions, and if we're going by the old 2014-era architecture, is just objectively more frontier-like than Summerset. Although Auridon Altmer can be just as snobbish as their Summerset counterparts, we don't see anywhere near the level of it that we do on Summerset. The question I have, though, is whether or not it's a simple oversight or a genuine difference in upbringing and culture. Given the ruggedness of Auridon, it may make sense that the altmer here don't or can't quite adhere to the same standards of Summerset altmer, but there's also nothing stating they don't follow it.
Throughout the entire Summerset chapter, and all post-chapter content, there's zero clarification (unless I've grossly overlooked something) on whether or not Auridon altmer hold themselves to the same cultural standards of Praxis that Summerset Altmer do. We don't see anything on Alaxon, calians, or anything of that sort in this regard, and there's been no post-chapter clarification to give us a yes-or-no answer. So, what does everyone else think?
