Roble Holy Kingdom

Roble Holy Kingdom  (ローブル聖王国) or more commonly referred to as the Holy Kingdom is a human nation located southwest of the Re-Estize Kingdom.

Background
The Holy Kingdom as it is simply called, is marked haphazardly on maps of the New World. Their neighboring area, the Wilderness, is inhabited by numerous demi-human tribes who are constantly warring with one another. The country’s border is protected by a wall, the 10,000 Mile Great Wall, keeping the savage tribes from encroaching. The kingdom's national hero is said to be a Valkyrie Knight, wielding the Sacred Blade.

Trivia

 * Demiurge was sent to the area and collected the skins necessary to produce magic scrolls.
 * The Great Wall here could be a reference to the Great Wall of China, built to keep out the Huns.
 * The Roble Holy Kingdom was where Demiurge originally planned to implement Operation Gehenna.
