O Dragão de Gelo ocorre no mesmo mundo que Uma Canção de Gelo e Fogo?

George RR Martin disse é não definido no mesmo mundo.

noybusiness: Is The Ice Dragon in the world of A Song of Ice and Fire like the back cover of it says?
grrm: No, it is not. The world of Ice & Fire did not exist when I wrote THE ICE DRAGON.

Mas, como a pergunta de acompanhamento indica, ainda há algum espaço de manobra para que seja retransmitido para o mesmo mundo.

noybusiness: So it's not a retroactive "nothing's stopping it from being in that world (in one of the legendary historical ages of winter) if we want to imagine it is, but nothing mandates it is if we don't" ambiguous thing, then?

... que GRRM deixou sem resposta.

A outra resposta mostrou que George diretamente nega a conexão, mas dragões de gelo (podem) existir em Planetos ...

Of all the queer and fabulous denizens of the Shivering Sea, however, the greatest are the ice dragons. These colossal beasts, many times larger than the dragons of Valyria, are said to be made of living ice, with eyes of pale blue crystal and vast translucent wings through which the moon and stars can be glimpsed as they wheel across the sky. Whereas common dragons (if any dragon can truly be said to be common) breathe flame, ice dragons supposedly breathe cold, a chill so terrible that it can freeze a man solid in half a heartbeat.

Sailors from half a hundred nations have glimpsed these great beasts over the centuries, so mayhaps there is some truth behind the tales. Archmaester Margate has suggested that many legends of the north—freezing mists, ice ships, Cannibal Bay, and the like—can be explained as distorted reports of ice-dragon activity. Though an amusing notion, and not without a certain elegance, this remains the purest conjecture. As ice dragons supposedly melt when slain, no actual proof of their existence has ever been found.

George também uma série de contos ambientados no que é conhecido como " Os Mil Mundos ". Então, enquanto ele diz que as duas obras não são do mesmo mundo, elas ainda podem estar conectadas ... Infelizmente, ele derrubou essa teoria também ...

[Q:] Asimov and Heinlein, late in life, both seemed to feel the urge to merge all of their books and stories into one huge continuity.

[A:] So far I do not feel the urge. No, Westeros is not one of the Thousand Worlds.

Então eu acho que temos que aceitar que no máximo os dragões de gelo em A Canção de Gelo e Fogo são uma homenagem a O Dragão de Gelo .
