I actually love this slice of Khajit lore. Especially;

"The ancient Khajiit heard the great roar of http://www.uesp.net/wiki/Lore:Alkosh the Great Cat King of Time (ed: known as http://www.uesp.net/wiki/Lore:Akatosh in the empire, and http://www.uesp.net/wiki/Skyrim:Alduin in http://www.uesp.net/wiki/Skyrim:Skyrim) and raced to his Voice. In three days' time they crossed the whole of http://www.uesp.net/wiki/Lore:Tamriel_(continent), resting not even for the moonsugar, for such was the speed of Khajiiti then.

They joined with the pride of Alkosh and were his strongest warriors. http://www.uesp.net/wiki/Lore:Lorkhan, (ed: http://www.uesp.net/wiki/Lore:Shor in the http://www.uesp.net/wiki/Skyrim:Nord) however, chose to give his roar to the http://www.uesp.net/wiki/Lore:Wulfharth to spite the Khajiiti warriors, for he was jealous of their devotion to Alkosh."

Once again there is this Akatosh-Lorkhan or Shor duality going on here with the 'roars'... What do you make of this book? More myth than fact?

It may hold something true , I love the fact that Lorkhaj is mentioned as some one to spite cats, because its forms nicly with theory that Khajiits may be related in some way to mer, so them being in their myth against God of mortals, is really nice touch

The relationship between Nords and Khajit is just plain weird.

We have Pelinel accidentally slaughtering a bunch of them before realizing they were Khajit (which implies some sort of regret) probably because they took on the form that looked like Elves.
We have Wulfharth respecting them dearly (apparently).
We have Nords advising (although unsuccessfully) how to beat the Bosmer.

However there is Lorkhan not liking the Khajit. I suppose this kind of supports my whole Shor/Shezzar =/= Lorkhan thing...

It seems to largely follow the same events as the Five Songs of King Wulfharth. The Khajiit appear to be responding to Alduin, who fought Shor during the time of Wulfharth.

It doesn't say Lorkhan doesn't like the Khajiit. I get the impression that Lorkhan does like Khajiit, which is why his jealousy is so strong because Khajiit like Alkosh more than him.
