Ice Dragon

[evenwind]

With GRRM mentioning that Dondarrion is a "fire wight", I started to re-examine some of the other things we've already seen in GoT. I'm wondering if that mysterious mist that came down off the mountain at Hardhome is the "reality" of an Ice Dragon.

From "The World of Ice and Fire" by way of the wiki: they are far larger than the dragons of Valyria and are made of living ice, with eyes of pale blue crystal, vast translucent wings, and breath of cold..

Except for the blue crystal eyes, not a bad allegorical description of the killer mist, no?
