@Narkalui, i totally missed your post about keeping the blood pure and the magic.
I follow you on that perhaps the forces of fire and ice are the two biggest magic players. I'm not completely sold on their being some higher powers that influence the world. It may just be that fire and ice are natural antitheses and therefore their magic wielders ended up going to all-out war with each other in aeons past during the long night. But the possibility is there, since GRRM s influenced by Tolkien. I can also follow you on that it's possible that Dawn is the legendary sword, and that some Dayne ancestral was the great hero. That those wielding fire and light 'won' and managed to 'seal' those who wield ice magic in the far north of westeros. It's all very much possible, wether it truly is like that, i really don't know.
Valyria was a vulcanic area. Dragons are creatures of fire. So it's not surprising they where found there. As for the people of valyria. They where not the only ones possessing magic in Essos/westeros. Magic very much exists in GRRM's world. Albeit it's no longer as much overt as in times past. It seems to me only natural that when surrounded by vulcanic area, the valyrians learned fire magic. (Aside from how to control dragons). Very much like the people living on the Royne learned water magic. I suppose in a similar vein you could say that those living in the north are more naturally gifted in ice magic. Since they live in the cold north. It may be that the others are in truth ice magic wielders.
What makes this all complex is, that the first men came to westeros and encountered the children of the forest. The northerners and the first men are more closely connected to the magic of the children of the forest and their gods. The wall and other stuff seems build against the others. So it's not a clear cut puzzle there.
Plus I'm not really sure of the timeline of the long night. But i take it the first men travelled to westeros. Came into contact with the children of the forest. Fought their war. made peace. Something happens to trigger the long night. Children+first men (or those not affiliated with the others) fight them alongside the forced of light and fire.
Same thing for the relationship between fire and light, dragons and the house of dayne. Sure the house of dayne has purple eyes, but are they descendants from Valyria. I got no idea. They don't seem to have a history of controlling dragons. I would also note that inbreeding most definitely had a negative impact on house Targaryen. Aerys was called the mad king for a reason. There was Brighflame as well, the septonlike king, Dany's brother viserius, ... Inbreeding made their lineage tainted by madness.
Wouldn't it be nice if we could sum it up like this
Ice/darkness magic - All kinds of magic in between like forest, water magic that is made from the clash between fire and ice - fire/light magic
Somehow i doubt it's that clear cut. So too with the people involved.
Magic, the mystery of the others, the long night ... still need to be properly explained by grrm. Somehow i doubt he wil do so. He'll probably choose to leave it mysterious.
It would also be interesting to find out at which time the order of the maesters was created. Since they seem to dislike magic, and prefer science. And therefore could be construed as enemies of all things magic. The citadel always seemed a bit evil to me (lol). I know i would not trust my maester if i was a lord. I'd be sure to check up on his background. Make sure he knows his place, and loo to him should he tresspass the boundaries set by me and do something like read my mail.
