Vandalia Citadel was one of the Secret Citadels established by the Heralds of the Mended Wood. It was known for its inhabitants who had suffered a great deal through their efforts to resist Morbin Blackhawk's evil regime. It was ruled over for an unknown period of time by Lord Booker, before leadership passed to his son Lord Morgan.
The exact design of Vandalia's crest is unknown, but in The Last Archer it is mentioned that it includes the colors blue and gold.
- The map at the beginning of Ember Rising mistakenly spells "Vandalia" as "Wandalia".
