So last I checked Nozdormus location was still unknown right? I know he randomly pops up in a couple places as kind of a semi-phased out being.
Anyways I was just in Caverns of Time and I noticed something about those two blood elflooking dragonkin children standing in the swirly rune vortex on the ground. Their names are Nozari and Andormu and it made me wonder if these two dragonkin children could possibly be Nozdormu in disguise of some sort? Perhaps he separated himself because he was afraid of becoming the leader of the Infinite Dragonflight?
If anybody knows more, let me know. I don't know much about Nozdormu myself, and I tried wowwiking the info on these kids and it didn't say anything special about them.
(and yes I am aware they also have adult forms walking around the area)
