Swans are a species of large birds. Most of them live on Swan Isle under the rule of Lord and Lady Arcneck. 

In Urchin and the Raven War, Lord Arcneck searches Urchin out and asks if he was the one that freed the two Whitewings Swans, when Urchin says yes Lord Arcneck tells him that he's a friend to all swans.

In Urchin and the Rage Tide, Corr the Voyager travels to Swan Isle and is confronted by two swans; when he tells where he's from, the swans take him to Lord Crown.

Swans are generally neither heroes nor villains, viewing the affairs of Mistmantle Island from a distance.
