" It would be better if we were high up on one of the peaks in the Beors, where only a dragon could fly, he said to Saphira. Then no one would be able to sneak up on us, no one except for Thorn, Murtagh, or some other magician.
Some other magician, like every elf in the land? Besides, it would be cold all the time!
I thought you didn’t mind the cold.
I don’t. But I don’t want to live in the snow year-round either. Sand is better for your scales; Glaedr told me. It helps polish them and keep them clean.
Mmh. "
