Silly question

[Greyhawk]

By calling it a "source", you imply that it is official.

What you are describing – fandom posts and unofficial wikis – are fan speculation. They are not a source for canon information.

It's no good to say "I'd link it if it was official, but it's unofficial so I just vaguely alluded to its existence" – that has the opposite effect. By saying there are sources but not offering those sources as evidence, an uninformed reader just hears "there are multiple official confirmations that Au Ra really are dragons" and not that some person on the internet thinks it's a cool idea.

I think you need to read up on the definition of 'source'.
