Could the dwemer mixed with other elves? and are the dunmer the only elves that can grow beards? not that I'm implying anything....but I was just wondering since the dwemer as supposedly extinct

Nvm.

Dunmer can have beards. Lots of Dunmer have beards...not huge beards...but facial hair is present.

The Dwemer probably mixed with other Mer, but not to any large extent I think. Remember, the disappearance was instantaneous...literally *poof* and they're gone.

I think any mixing would have occured before the big dissaperance

Some Bosmer have beards. I don't think I've ever seen a Altmer with a beard, though.

I think there was enough of a culture gap between the Dwemer and other elven groups that interbreeding would have happened only rarely. The Dwemer split with the Altmer early, didn't they? After all, they were already settled in Morrowind before the coming of Veloth and the Chimer. And the Chimer didn't get along with them very well - they were warring off and on until the time of the First Council, so I don't think they would have mixed all that much. I can't think of any reason it wouldn't have been possible, though.

Wouldn't it HAVE to?

Well biologically, all men and mer can reproduce and create fertile offspring. Really Argonians are the only Tamreilic race (and maybe Imga) that can't produce fertile offspring with men and mer.

But, though there might have been a cultural divide, I don't think half-breed children were impossible. First off, there were always the Orcs, allies to the Dwemer at many point. A Dwemer-Orc was probebly something )however uncommon) that existed. And then there's always [censored]. Dwemer have very low moral standards. If one were to [censored] a Chimer woman, then the Chimer would probably scorn the child but the Dwemer might very well adopt the child. Then, for all intents and purposes, a child raised Dwemer IS Dwemer.

I think Dwemer would simply be too alien and 'self'-absorbed for any meaningful mingling with other races on any large scale. Visits by traders, scholars, rulers and their agents - and perhaps the one-in-a-million social renegade - would likely be the limit IMO. I'd expect no closer contact between Dwemer and other races than there is between Imperial colonists in Argonia and the untamed marsh tribes.

I think maybe the Dwemer preceded the Altmer.

http://www.uesp.net/wiki/Tamriel:Notes_on_Racial_Phylogeny seems to suggest that any races can breed with each other, but it is never stated whether or not the dwemer did. :shrug:

I seem to remember Yagrum Bagarn mentioning something about the Dwemer breeding with the other races when consulted about the disappearance of the Dwarves. Not certain, however.

What about Yngling Half-Troll the Hlaalu Counilor in Morrowind? Or "Half-Troll" was just a name and nothing more?

That sounds like an epithet, yes.

Probably referring to his ugly looks or a rude behaviour. I would go for the last.
If we're going to talk epiteths, "Dumac Dwarf-Orc" is definitly the most interresting.
