Remember, this is the third age, after bilbo's party. The "last" dragon, Smaug, has been slain. He came from the withered heath, which is was the only place where dragons were known to live during that time. After smaug, no other dragons were seen or heard of. This is the same reasons that Mevans will not add things like moria dwarfs and some other factions, because theyre extinct at the current time.

Technically, dragons should not even exist in ME anymore, but if they must, they should be extremely rare, like only in withered heath.
