Re: The Ice Dragon, GRRM says the story isn't part of ASoIF (ie; it's not canon history), but that doesn't technically exclude it completely. As that Blastr article states, it's sort of referenced in ADwD where Jon remembers being "told a story of an Ice Dragon in his youth". It's logical to assume that would've been told to him as a child at Winterfell, by Old Nan. So, I'd always taken it all to mean that The Ice Dragon is the ASoIF equivalent of a fairytale. It's not a "true story" about real historical events in Westeros, or wherever in that world it supposedly takes place... but it is one of Old Nan's many tales. Like if GRRM had decided to separately write and publish the story of the Rat Cook at the Nightfort, or any number of her other storys. It's been well established that Westeros and Essos have many legends and folktales, few if any of which are actually genuine historical accounts from the ASoF universe. With all the connections/similarities to the ASoIF universe in The Ice Dragon itself, plus Jon's reference, I don't think my conclusion is unreasonable. Whether that was George's original intent or not is debatable since Ice Dragon was written long before ASoIF, but you can't look at that and tell me he didn't intend to refer to it when he wrote that line in ADoD.
