I want to talk about the parallels between the norn and the asura. Under cut, long yap session ahead
Let's start with the basics- they're the two most ignored races of the main 5 when it comes to lore. And often times, the interesting lore they DO have is hidden in the game.
A great example for asura would be the nuclear disaster (not literally, but it seems to be very similar) at Thaumanova. While there is the fractal, you only get the deep parts of the effect it has when you talk to the refugees around the area. I'd suggest reading @ratasum 's posts about Thaumanova, and besides that they've done quite a bit of digging on asura lore. You could probably get more on the little rats than what's on the wiki- spoiler alert, the wiki doesn't have a lot.
For norn, the lore of being shapeshifters and the lore of the spirits is really easy to miss. In fact, once you get to IBS, it's entirely possible to not even know norn could shapeshift until then if you didn't play one, hadn't read Edge of Destiny, hadn't talked to a whole lot of NPCs, which is a combo that's really easy to have. And according to a Jotun bard in Hoelbrak, norn used to be some of the most powerful magic weilders in Tyria.
Now: the norn, asura, migration, and loss of identity. Both norn and asura were forced out of their native homes by elder dragons. Both lost quite a bit of their language (in canon. My hc goes lalalalalalala I can't hear you). (Both are, also, fitted into tiny squares of stereotypes. Norn are stupid drunk barbarians, asura are sketchy mad scientists. Obviously, outside of main characters, when do we encounter norn and asura? The Svanir and Inquest, of course.)
What? They addressed this in the Icebrood Saga? A miracle! What is it? How do they do i- oh.
It's one conversation with Braham and Taimi arguing.
Are we ever going to mention this again? Nah.
It's also worth mentioning that norn and asura both have societies and cultures that are based solely upon achievements and respect, even if hunting a violent wurm is a bit different from making a scientific breakthrough. It is the same at its core.
Also less of a parallel and more of a perpendicular, norn are the biggest race and asura are the smallest.
Idk maybe I'm just seeing stuff that isn't there in mourning for the lack of content. I just think they're neat
