Hey there everybody

So I know that the two moons disappeared for two years during the Void Nights, before suddenly returning, and that the Thalmor took the credit for it. Assuming their claim was true (I don't really think it is, but assuming it is), I'm left wondering why they'd want to return the moons in the first place, as they are pieces of Lorkhan.

Does anybody know how exactly the Void Nights began or ended? Or can anybody offer an explantation as to why the Thalmor would want to restore pieces of Lorkhan to the world?

Thank you

Edit: I understand why getting the support of the Khajiit would be beneficial to the Dominion, but I can't see that being their primary motivation for restoring the moons, if in fact they did.

I don't think no one knows how they began or truly ended, it is unknown if the Thalmor themselves brought them back or they'd immediately claim that they brought them back. Strangely, they had the full support of the Khajitt after this for the Thalmor armies since those cats just love those moon as it's a part of their purpose and some genetic mumbo-jumbo thing.
