The "Redwall" novels are characterized as fantasy, but contain little in the way of magic or the supernatural, apart from the anthropomorphism of the animal characters. The sword of Martin the Warrior is believed by many characters to be magical, and vermin occasionally try to steal it for this reason; "Mossflower" reveals that it was forged from a fragment of a meteorite at the volcanic fortress Salamandastron by the Badger Lord known as Boar the Fighter. The role of "monsters" in the novels is played not by mythical creatures, but by real-world predators such as adders, sharks, and wolverines.
