Just a funny thing that I discovered when I was reading on the UESPwiki. Here the quote : "Jyggalag can also be considered Anuic, as both Anu and Jyggalag represent Order"

Isnt that a contradiction. Its true that everything would be always the same under his rule but at the same time he is Daedra Prince which makes him padomaic by nature.

What are your thoughts about this?

His order is chaotic.
But being a Daedra Prince isn't completely same as being padomaic.
If I'm correct, Meridia is anuic. Is she?

Not really, but she is different from the other Daedra (along with Malacath and Jyg)

Daedra =/= Padomaic

Aedra =/= Anuic

But generally speaking, you're right. Jyggalag, Meridia, Malacath and possibly Mora and Peryite seem to have some Anuic traits, though.

Jyggalag's intentions are anuic. His methods tend to lean towards chaoticness, but his end result and goal is anuic(perfect order)

As others have said, the Et'Ada are a diverse group. Only Anui-El and Sithis are the true paragons of anuicism and padhomaic. This is why we have a Daedra(Jyggy) wanting stasis and an "Aedra"(Lorkhan) wanting change.

Jyggalag causes strife amongst the harbingers of strife. He does not represent stasis. If he represented stasis he wouldn't try to take over everything with his Order.

Yes he would, because he's OCD, and he can't stand watching his inferior brothers doing stuff.

Which makes him Padomaic.
