A Voyager of Mistmantle is a Mistmantle animal that can go beyond the mists more than three times, and can travel in and out of the mists by water; in other words, the mists have no containing powers over them. A Voyager is extremely rare, only appearing once every two-three hundred years, with usually many generations in between one Voyager and another. Animals who are Voyagers are extremely famous, as they are so rare. Most Voyagers are otters, as they are the best at swimming and sailing. Only three voyagers are known to have existed in Mistmantle's history.
The only known Voyager who played a major part in any book was Corr, who first appeared in book 4. There have been 3 known voyagers before him, most of them were otters. An otter voyager named Lochan is mentioned in book 3.
