Wrong quote... oops.

The Grey Maybe is Nirn.

Or is has Nirn been constructed at the heart of the Grey Maybe? Which is the chicken and which the egg?

ooohh..

And with that in mind, assuming that Nirn was constructed in the heart of the Grey Maybe, do we know that Lorkhan tricked the Aedra into creating the Grey Maybe, or should the real question be who or what created the Grey Maybe?

Or...

Are my questions completely stupid and well-known already... haha

It seems you are posing the assumption that you already know the answer/s and so are not bothering with giving them because 'everyone' knows them. but I am a mere seeker after knowledge so please enlighten me, pin down your sources and show me how they are relevant please.

And do tell. Where does it say that Nirn existed before the Aedra entered the Grey Maybe and where does it say anything about the creation of the Grey Maybe? As far as I have understood to this point from what I have read it seems that the Aedra just came upon it and were intrigued. It may be the Grey Maybe is a phenomenon that came of the interaction between Anu/Padomay etc ofc - or does it actually represent something other? And it may be that Nirn was there already formed or that it was formed of the substance of one or more Aedra when they discovered that they could not exist in their previous state/forms within the Grey Maybe and were trapped by it.

If it is formed of the substance of several Aedra then it is a unique plane(t) is it not? not only unique as far as th eAedra, bu8t also as far as the Daedra are concerned.

If you cannot answer those questions straight away maybe you could try a bit of lateral thinking in the absense of actual info. If you have the info then please explain where the limits of the Lore are in this, thanks.
