Shikine Island (Shikinejima) is the site of a Shadow Empire military facility, which hosts the airstrip used by Prince Schneizel's Avalon upon its initial arrival in Area 11. This was originally the site of a meeting between Princess Azula and a V.I.P. (who is later revealed to be Schneizel), however this was interrupted due to an attack by the Yasugarita Knights. The commander of the facility is Lieutenant Colonel Fayer (ファイエル中佐).
The Shadow Empire takes up the entire Lost Lands and almost the entire 5 Great Nations, except for the Land of Water and Nagi Island. They also possess the eastern and northern part of the Feudal Lands and all of the Warning Lands.
