Jeremy de Montfort, known by his regnal name as Jack III is the Prince of the Calbain since 1733. He also holds the titles of Grand Duke of the Brettish Isles, Count of Ynys Herydd and Emperor of Andilar, under the regnal name Jack II. As closest kin to Prince Deiniol, he succeeded him upon his assassination by Princely Guard Captain Royce Wayne as part of a plot to overthrow the Prince. Being himself implicated in part of the Alwyn plot, Prince Jack III was granted special emergency powers for 10 years that included rule by executive degree. This marked the first time since Prince Jack I that a Prince of the Calbain had significant power within Calbion.
Inducted to the Order of Ash and Elm, with the rank of Knight Commander, during the Quarter Millennium Gala in Huyenkula in 1752.
