Very well, I will go into more detail. CHIM is supposed to be a kind of magical super-state where, if you manage to access it, you can totally break the rules of reality and do all kinds of crazy stuff. It's a bit controversial among the fan community because there's never been any in-game confirmation that it's truly possible to achieve such a state, and as far as I can tell, has only ever been referenced by Vivec and Mankar Camoran in their respective writings, and even then obliquely. They also both wrote in very abstract, metaphorical terms, making it difficult to determine at any time what they actually meant. Anyway, Camoran claimed that Talos used CHIM to transform Cyrodiil from a jungle into a temperate grassland/forest, and an OOG book that Kirkbride wrote - which was later quoted in part in Skyrim - suggested that he used the Thu'um. This vague explanation satisfied many lore-minded fans who noticed the discrepancy, but then along came TESO, and prior to the game's release, we got to see gems like this:
The worst part was that this wasn't even true. You might remember that I briefly addressed this earlier in the thread:
I found a letter addressed to someone named Parsifal. It made me smile.
Anyway, I am now in Hammerfell. Hopefully it'll be more interesting than High Rock. Although there is at least one cool thing about High Rock that bears mentioning here:

That's right, Kirkbride's wonky theory about magical towers protecting Mundus received some in-game acknowledgement! And a couple of people there discuss the possibility that it was these towers that were responsible for transforming Cyrodiil. On that subject, you might notice that the guy saying "I have no idea what that means" is the same dull historian who wrote this, which is even controversial in-universe. I don't know if ZeniMax is ever going to expand on this or anything, but even the implication that we shouldn't be taking the whole "derp transcription error" explanation at face value is a good thing.
There's a guy on Reddit who explains it better than me:
http://www.reddit.com/r/teslore/comments/2avasd/new_hist_lore_in_eso_spoilers_ye_be_warned/cj0ofcuThe transcription error thing is not supposed to be taken at face value. It shows up in the game as people trying to explain oddities that are clearly more than mere transcription error, and even has at least one text that calls bullshit on that explanation. If there are still lore buffs who are mad about that, then I don't think they're paying enough attention.
Basically, "transcription error" is code for "metaphysical shenanigans being misinterpreted by myopic scholars" such as books showing up before they were published, or constant reference to a jungled Cyrodiil.
This follows a tradition of sorts. One of the best books from TES III is an attempt to discredit the Dragon Break of the Middle Dawn, written by Fal Droon. It's awesome because it appears to have actually been written after the events of TES IV and thus its presence constitutes a Dragon Break in itself. It talks about the fall of the Septim line in the past tense. And what is that name, Fal Droon, an anagram of? Darn Fool.
If you see a painfully boring explanation in the lore, rest assured, it's probably just wrong, on purpose.
So it turns out that the Mane sometimes wears a helmet that has other Khajiit manes on it. That's uh, well, it's something, I guess. It's a bit of a dilution of the description in the PGE, but at least they didn't forget why he was called the Mane to begin with.
