Hircine and Hagravens, - any connection? Options

[ghastley]

Since Hircine is the Father of Manbeasts, it seems appropriate that he'd have something to do with all the intermediate forms, such as hagravens and harpies

However, the Argonians and Khajiit aren't his, and nor are Winged Twilights, Spider Daedra etc. So what are the "rules", if any? Does it need to be a transformation that can go both ways?

And if not Hircine, then do the hagravens have any Daedric affiliation?

I haven't quite figured out haggies and harpies yet. In general though, I view the Aedra as very good at creating but having little interest in managing their creations, and not very good at change when they do attempt it. I view Daedra as lousy at creating anything new but very skilled at manipulating and changing the creations of the Aedra - blending women and spiders to make spider daedra as only one example. And the Daedra, of course, are quite keen on actively screwing with worldly affairs.
