At the suggestion, Dread fired (ha) Svartis a faintly resentful, reluctant look.
"Fire doesn't work," he reiterated, rather upset by all this. "Watch."

"I don't think it will notice that. Pick a way. I will go with you," he insisted. Then he nodded off, forward, through the snow; he knew that Emuh's cave was on the northern face of Polaris, just a small divot compared to the size of Polaris itself: but the whole north of this cave was full of snow. "I think it was that way," he suggested, but he didn't seem bothered, one way or another, about finding it.
It was likely the cold getting to him: he was somewhat miserable, quiet and dull. Dread was most certainly not an ice dragon.
