The fisher is an intelligent and predatory species of mammal present in the Mouse Territories.
Although closely related to the weasel and ferret, the fisher is far larger. Unlike its cousins, the fisher does not form complex societies and tends to live alone — although a few may band together during the mating season.
The fisher is also relatively technologically unsophisticated. While it may improvise simple clothing, tools and weapons, the materials it uses are basic and the results are crude. It is not wasteful and will put every piece of what it kills to good use.
The fisher rarely speaks; not because it is unable, but because it wishes to remain silent while hunting prey.
