This isn't really about any theory or question or desire. Rather, I've got a challenge for you guys.


Say a brand new, playable, primary race is added in the next entry. These guys are as advanced as everyone else in Tamriel and somehow well integrated into mainstream culture for maximum playability.... But this is all within decades of TESV.
Try and come up with some explanation as to how this can go down so rapidly- describe this race and briefly discuss their culture, why they're there, and how people got used to them so quickly.
Rules-
1.No pre-existing races allowed, but you can include highly developed offshoots of any race. The more different the better.
2. No "returns". We all know if the Falmer somehow manage to return to civilization, it'll take centuries or millennia. And the Dwarves/Akaviri men/Those silver dudes from BM are gone for good.
3. Write from the time of 4E 347
