where do the khajiit ( the cats, not the bosmer/human looking ones ) descend from? I keep hearing they come from Mer, but i've also seen someone say that they were in Tamriel before Mer and proof to back it up?

There was this race called the ehlnofey, whom to my understanding were created by footprints, remnants and parts of spirits trapped on nirn.
This race spread over nirn and were the origin to most of the races we see today. Khajiit in this case, most suspect were ehlnofey
of tamriel who were warped or changed by Azura's influence. There is also speculation about them being changed mer, but this is unlikely.
For a quest in Skyrim asks you to gather blood from all of the elven races to be used to fool a device, and khajiit is not among them.

I know about the Ehlnofey and about the Khajiitian ( lol ) creation myth with Azura shaping them into the most beautiful creatures i just thought they would descend from another being like how the Aldmeri ( or whatever the orignial elf's where called ) where the only Elf race until some of them became Dunmer from chimer, the Bosmer, Altmer and the Wild elfs/now elfs ect.

I don't think their mer, because Orc's are supposed to be a radically changed Mer, so are Dunmer and like you said that quest to take their blood doesn't need khajiit but then again, it doesn't need Wild Elf's ( but then again, there not even included in game )

I guess Azura Changed some race into Khajiit , seeing as how she had the ability to alter the looks of the dunmer

Not entirely sure, either they were there already or they are descendants from other Mer... Your guess is as good as any.

Their creation myth has them as the more evolved version of the Bosmer, and there's no contradictory account I'm aware of, which makes it fairly reliable. The only playable race which isn't descended from the Ehlofey are the Argonians, who were created by the Hist and/or are a part of the Hist life cycle. Or something. The Hist are very mysterious.

I thought the hist where the only non-Ehlofey?.. I don't think they evolved from Bosmer but i do think the ohem/ohem-raht ( or how ever you spell it ) do come from Mix breeding between Khajiit and Mer as Early mer accounts of Khajiit only listed them as uncivilized cat people.

I personally think they have some relation to the Ka Po Tun. I THINK ( its just my opinion ) the khajiit are a bunch of Po Tun that travelled to tamriel from akavir and features changed due to the many years of adapting to their new home.

No, the Ohms were just born on a different phase of the moons, and the only account of the khajiit is that they were Ehlofey shaped by Azura before Y'ffre stabilized everything's forms.

It could be a wierd (or is it spelled weird?) crossbreeding between cats and Mer, with the moon in a certain phase. Oh, and Moon Sugar was probably involved.

Doesn't A Children's Anuad suggest there were multiple plane(t)s of existence that were broken by Sithis then reassembled? A race from another plane(t) transplanted to Nirn?

"Enjoying Torval, this-one trusts, Clan-friend Xormades?"

"Indeed, your Maneship, it is very...interesting. Like watching the Niben run through a dream. Though I had a question about your people: I have noticed that some Khajiit are like Mer in-guise, whilst others are like yourself - upright-walking cats - whilst there is a third phylum not at all unlike the small felines we keep as pets in Cyrodiil. How can this be? Are all these seemingly very different catty nations but one folk?"

" Indeed we are, Xormades. To understand you have to look back to the first time, the shut-eye-era of the World-at-Teat, when Aka-Tom first climbed the M'ntiajjh tree to catch Lorkhaj (for he had in his teeth the Tom's prized sandclockbird). This drove Khenarthi-cat crazy, she had loved them both so, and so she mewed with such force as to blow all the nursing kitties off of Curled-Up Nirni's teats. So Jjj'frai took in her teeth the ja-Kha'jay, the moon-yarns of Jone and Jode used it tie all the kitties down.

But Az'rah, rightly seeing that the moon-yarns strangled the kitties beauty and made them into ugly, stupid things - the elf-folk and men-folk (this-one means no offense, Xormades, this is merely how the tail is told) who could not love paradox or the clever patterns that Riddle'thar weaves. So she leapt down from the High Sill and took hold of the kitties who still had neck-naps and took them far away from Khenarthi's whirlwinds, to this-place, placid Torval. Then she licked us clean and taught us the secret of the ja-Kha'jay, how to turn the moon's sugars into wisenips that would allow us to see the yarn-threads and beat them back into clever patterns.

So there it is, Clan-friend. The bald-cat, the burden-cat, the battle-cat, even this-one, big-decision-cat, are all Khajiit. The difference is, that as fresh kitties, when we succored on mother's milk fat with wisenips and first opened our eyes, we batted at the moon-yarns as we saw fit. In your people's words, it's a matter of choice. "

Whitestrake killed thousands of Khajiit because he thought they were a type of Altmer. But he was a bit crazy.

But no one really knows how they came to be. The best explanation is that they're Ehnholfey changed by Azura.

If you direct yourself to the UESPwiki on the subject of Khajiti's you'll find a lot of interesting information, like how khajiit children take one of about a dozen forms depending on the phase of the moon when they are borned, being their connection to Azura. You might also like the information regarding Topal the pilot who recorded the existance of the Khajiit people long before the first Bosmer Settlement.

With their distinct lack of involvement in the Mora quest involving mer blood, they can be logically removed from the mer family, but the uncanny resembelance of some
of the Khajiit most specificly the Ohm-rat who is basicly a wood elf with cat ears and a tail (Think Hentai Cat person) but they can not be mix breeds as Man nor Mer can interbreed with a beast race (Argonian and Khajiit). What is likely though with everything we know is that the Khajiit did evolve from a form of cat/tiger that was probably native to Tamriel like the Argonian's and were evolved unnatturaly by outside factors such as Azura wether directly or indirectly, and the Hist, again it is not known if these alteration's were intentional or just the side effect of something else which leaves a large part of their creation rather mysterious and unknown.

i thought that just no well documented records exist about mix breeding?

or atleast i thought no one knows for sure

We don't know whether it's possible or not. Whatever info they have is not properly documented. Doesn't mean there isn't any, just that there's no proper documentation of it. It's not like anyone can tell since there's no half-breeds, either. An Imperial male and a Khajiit female will produce a normal Khajiit child, and an Argonian male and Nord female will produce a Nord child.

Personally, I'd say that cross-breeding with the beast races is possible, but it's not something people would readily admit to. Either that, or the report is faulty and any documentation they have is just ruled "inconclusive" because of their bias.

The Moon(s).

I don't think it's necessarily Aldmer, just Ehlnofey that didn't wander.

Thanks for all the replys guys its interesting to know the khajiit take different forms depending on the moon they are born under

I was gonna say that. Good answer.

From what I understand (Arena/Daggerfall lore. All future games are to be ignored in those departments when it contradicts), the Khajiit are descended from the previously-existing Great Cats of Elsweyr.

Hmm where is this from or is it standard HQ? This indicates the moon does not truly control the formation of the Khajiit into their various forms but it is a choice at birth correct? Interesting. Or I am getting HQ'ed

It could be that Khajit souls choose when to enter Mundus, and when they choose, they become different types of Khajit.
