David Maxwell
Admiral David, Earl Maxwell was one of two claimants (along with Edward, Lord Campbell) to the throne of the Principality of Caledon upon the death without issue of Prince Colin. Early on during the Dynastic Crisis of 1024, Maxwell's forces had the upper hand in the struggle and Maxwell had himself crowned David V, Sovereign Prince of Caledon. In late 1024, however, at the Battle of Dunbarton, Maxwell's fleet was defeated. Maxwell made his stand at Rob Roy (Reaver's Deep 1917), one of his last bastions of support, until it became clear that his cause was truly lost. Then he fled, first to Skye (Reaver's Deep 2018), later to Germaine (Reaver's Deep 2019).
His current descendent, Roger Maxwell I, continues to style himself the rightful ruler of the Principality.
