I'm in the camp that Dragons are just another unit in the production options. You probably need something special to unlock that option (Arkenhammer), but there is not reason to think that anyone can generate them. I would be interested to see if Stanley still has to "tame" this one before Parson can control it.

i'm just glad we finally saw what GK was building and this implies that production is a one time expense that doesn't require turn by turn payments (unless one of Sizemore's gems got consumed).
