Well... I've been thinking about it, and I'm rather curious. The dragons being resurrected and brought back to life, they did have to come from somewhere in the first place right? So... this made me start asking questions, Are dragons supposed to be a natural part of the world of Tamriel? If they are, then how are they born or created? and more so, if they are part of the world, then obviously they are not all like Alduine. there is at least that I know about that isn't the leader of the greybeards.
So, all of this is leading to one thing, there has to be natural dragons which have nothing to do with Alduine right? So... where are they? What have they been doing all this time, since they were supposedly hunted down to endangered status? As Farengar in White Run said, many were killed in the dragon war but some survived into ancient times. So where are these survivors?
even bigger question, makes me only wonder even more. Where are the female dragons? Are there even female ones? Something spawned Alduine right? So where is she?
