Beings that knows about Etherna would not be a weak being
But that also means, that it would not be easy for those beings to talk to him as an equal and even gave him all of the necessary information
However, now he has such being that volunteered such information
So, he is more than eager
Especially when a being like Odin selflessly given him the opportunity to understand the Etherna from his point of view and his opinion of the Etherna.
And Azief had already summarized some of Odin thoughts about the Etherna
He respected them, feared them, and is in awe with them. But Odin clearly did not think that the Etherna is a perfect being
Azief could not help but sigh in his heart.
There is always something to learn.
Time has blurred all information about the Etherna and sometimes he couldn't help but think that the blue crystal whitewash all the bad things about the Etherna.
The blue crustal is the crystallization of Etherna knowledge.
