On the questions about the last hero.
I was just re-reading the part of GoT when Old Nan tells Bran the story. She didn't finish the story, because Bran was taken down to the Great Hall to meet Tyrion who brings him the sketch of the saddle.
I don't remember the story being finished afterwards, and Old Nan was asleep in her chair when Robb took Bran back to his room.
The story ended with the Last Hero's sword breaking, his dog, horse and his friends dying. He didn't find the children.
Dragonsteel is not Valyrian steel-Sam finds records of dragonsteel and he and Jon only assume that it is Valyrian steel.
It would be too easy, IMO, if dragonsteel and valyrian steel were the same thing.
I think it's possible that there's dragonsteel on Dragonstone.
But we already know that there's obsidian there, so we may be in for a surprise on dragonsteel. I just don't see the point of introducing valyrian steel and obsidian into the story, and then introducing dragonsteel which will turn out to be dragonsteel.
May be Dawn is made of dragonsteel.
