I understand what they are, mostly; according to resources they are a fox-like [Vulpine] race of beings that are very possibly and strongly related to the Khajiit. A race that hailed from the Black Marsh and the Race that founded the city of Blackrose.

From what popular belief is, people think they are extinct. However, where is the proof? Black-Marsh is a tricky place, and so is many other lands. There are plenty of places that these creatures could thrive in unnoticed.

Also, Being Vulpine in nature, they I would assume, would be highly-intelligent or the most intelligent beast-like race in Tamriel. Which, if true, wouldn't they easily be able to hide themselves from any other race if they felt it necessary?

So, if one was to make a architecture, mod, and race about them, would it be so lore breaking, due to the uninsured understanding of whether they are extinct or not?

If there is no substantial evidence of their extinction besides their absence, I would say that such a mod would not be lore-breaking.

However, having them appear out of nowhere without a reasonable explanation would be inadvisable.

hmm, well, if you want to mod them in, I'd avoid a sudden "everyone/significant portion of a community knows about them now" situation.

Should I point you to the Falmer? The problem with these guys is, unlike the Falmer prior to Skyrim, we barely anything about Blackmarsh. Its entirely possible that there are some traces or references to them...the problem is we don't have any. As for a mod, feasibly. One thing is for certain, they would most likely not reside in Skyrim, let alone inhabit it. Problem arises is that you'd be working with next to nothing on them.

Oh no; it'd be more of a randomly stumbling upon a hidden civilized; maybe they have stealth technology that can hide entire cities. .. or magics. OR have a unique way of blending in with everything else no one ever notices, not even the Argonians. . . . That would be interesting.

I speak of Morrowind mod; Skyrim bores me.

Well; if there is nothing on them; I could create something on them, without entirely Lore breaking, while simotaneously taking in past surrounding influences to how they would behave, their architecture, e.c.t.

Which obviously the Argonian's and very possibly Khajiit had great influence, or Jungily and Swampy lands would influence their style as well, then finally personality of a fox.

They're dead, and that's all.

prove it.

1 - they thought the Dragons extinct. they weren't.
2 - They thought the Sixth house and Dagoth Dead. They weren't.
3 - They thought the Falmer extinct. They weren't.
4 - The Chimer still live even up to the Skyrim era [not the Tribunal obviously]

4 isn't going to be literal. Chimeri in spirit, but not actually Chimer. To be a Chimer would mean immediate death within Summerset Ilse in the 4th era.

Also, 1 and 2 are wrong. Dragons were always there, just that no one knew where they were. With 2, everyone in Morrowind knew about the 6th house and their incursions.

Incorrect; For a good time, people thought dragon's were extinct, but they weren't. That's where my point was.

[before Morrowind] people had thought Dagoth Ur dead and the sixth house gone when they in-fact weren't. that is another point.

I read in something recent that the Chimer still exist in the Summerset Isles, even up to Lore-date, today. As for whether they'd be killed for being chimer? I wouldn't understand why. Chimer of elven bloodline, and if those Chimer had agreed to join the Thalmer then I wouldn't see why they'd be killed?

explain?

1) Okay, which point in time are you going off of, because you're bouncing around now. Even in the late 3rd era (during TES I) dragons were known and there, as seen in Battlespire, and one was used in the late 2nd era by Tiber Septim. There have always been dragons, but they were hardly ever seen.

2) Again, which point in history are you going off of? Some early point in the first era or later?

3) About the Chimer in Summerset. To be Chimer, one would have to completely disagree with the altmer point of view. To be a Chimer is more to do with culture rather than race. The Thalmor would find them to be thee most blasphemous, heretical, and the most vile of people ever known, for they are mer who willingly broke the altmer view to see a very mannish view of the world. With man, the altmer could at least reason they're low beings who are just vermin to be stamped out. With Chimer, it's vastly worse because they are mer.

I go at certain points in history; specifically with Dagoth and the Sixth house, not long after Dagoth was thought to have been killed.

As for the Dragons. In morrowind the Talk of Dragons was as if they were extinct. And I believe in Oblivion as well.

As for the Chimer, well, I mostly refer to the Race rather then the belief. See the Chimer in the summerset Isles are the one's who escaped Azura's curse due to them refusing to follow the Teachings of Velothi.

Then they really are not Chimer, for the only thing really setting them apart from the Altmer is culture, which is intrinsically tied to belief.

They are still Chimer in the Summerset Isles.

In any case, this is all irrelevant to the topic of the Lilmothiit.

Is it not?

It is indeed- Just I straying off-topic to prove a point. lol. Besides that; any thought's on the Lilmothiit race?

They were awfully foxy ones.

Well . . .isn't that new to me. ahahahahahahah. something more literate? As of ideas what they were like customarily wise and culturally? Possibly Architecturally as well?

Thats all we know, besides the fact they made a longstanding city quite deep in Black Marsh.

That was in the late 3rd era, before the rise of the Thalmor. Outdated information is outdated.

Hahah. Indeed that's all we know; I was asking more of speculation and opinions and ideas of what they might be like in those categories. xD
