" Another, Falshed knew, called itself a mountain weasel. Yet another sported a very long tail. There was not, as he had always imagined, just one sort of weasel in the world, but a great many varieties, who fetched up in places like this, an international crossroads. The same could be said of badgers. In his travels through Eggyok the chief had met stink badgers, ferret badgers, hog badgers and honey badgers, all slightly different. When it came to martens there were over a dozen, from stone martens to fisher martens to yellow-throated martens. There were even thirteen species of otter! Yet, so far as he knew, there was only one type of stoat. What did that tell him? That stoats were special? Or that stoats were inferior "
