Here's the obligatory MK post when this topic last appeared. Is it true? I dunno. I'm inkling it is but that's only because I have high regards for MK.

Depends on yer motive.

South Hammerfell was colonized by high elves before Men, at that time they called it Hegathe. Maybe the Thalmor just make claims for every territory once inhabited by their kind. Or:

- they just want to surround Cyrodiil, both on earth and sea
- there's some old dwemer/elvish stuff they want

Back on topic, we don't have much details about the consequences. The moons are not juste idols for khaajiits, the make them the moment they are born. Bethesda never gave details but imagine that without the moons, there are no births at all: all babies are born-dead, or turn to horrible and mindless monsters the parents must put out of their misery... We can imagine that the whole event was made for the sole purpose of preventing the Mane's birth (thus leaving Elsweyr without a proper leader) but turned horribly wrong and cost the lives of all the khaajiits-to-be for two, very long years.

Such things happened before.Inthe book "Where Were You When the Dragon Broke?"

“Do you mean, where were the Khajiit when the Dragon Broke? R'leyt tells you where: recording it. 'One thousand eight years,' you've heard it. You think the Cyro-Nordics came up with that all on their own. You humans are better thieves than even Rajhin! While you were fighting wars with phantoms and giving birth to your own fathers, it was the Mane that watched the ja-Kha'jay, because the moons were the only constant, and you didn't have the sugar to see it. We'll give you credit: you broke Alkosh something fierce, and that's not easy. Just don't think you solved what you accomplished by it, or can ever solve it. You did it again with Big Walker, not once, but twice! Once at Rimmen, which we'll never learn to live with. The second time it was in Daggerfall, or was it Sentinel, or was it Wayrest, or was it in all three places at once? Get me, Cyrodiil? When will you wake up and realize what really happened to the Dwarves?”

Good eye! Good eye. Xcept now khajiit no see moons, cuz thur Mayn has the dedpox.

That's such an amazing paragraph...
