Yep, we had that already too, both here and in the review of 324.

It certainly would explain how it's possible that there are 10.000 members of a species that the majority of mankind considers either extinct or just a legend that never really existed.

Apart from them living on some remote island and killing everyone who got near them, this is really the only explenation I can see why noone ever stumbled upon so many of them. Dragons, with their massive size, aren't exactly easy to overlook after all.
