*still glancing towards the Chimer*
The Altmer (tries to) look like they
think the Aldmer looked like. The Ideal. A stereotype.
I mean, just search anywhere (especially any "art" community) for Viking, and you'll get a good idea of how they
didn't look. The same goes for the Altmer version of Aldmer, however, these guys are working towards becoming their ideal, through selective breeding and all that jazz. Therefore, I think the Chimer would recemble the original elves better, as they abandoned many of the Altmer philosophies way back.
But couldn't the Orsimer have been a "tribe" of elves within their own right, seeing as the Chimer were too? The very fact that they were the followers of Trinimac suggests in itself, to me at least, that they must have been more warrior-like than the Altmer.
Possible. But if I remember correctly, it had more to do with them being oh-so-ashamed over what had happened to their leader.
