Revlon Empire

Revlon Empire or Old Revlon Empire was large country in continent.

Background
The Revlon Empire was the largest country on the continent six hundred years ago, before the country was divided into two countries, the Great Leburan Empire in the east and the Holy Leburan Empire in the west. It was this nation in which Hanzō established himself and helped create an elite spy corps that served the empire. However due to the success of Hanzō and his organization, he was greatly feared and envied, causing many attempts on his life, which he dodged and escaped. Soon after the empire became embroiled in a civil war over the succession of the throne. Ironically Hanzō worked behind the scenes to ensure that both sides of the conflict would keep fighting, long enough for him and his newfound clan to escape and later form the Jinshin Clan.

Rhoden Kingdom
It is unknown what kind of relationship the kingdom had with the original Revlon Empire, but six hundred years ago when the kingdom attempted to conquer the Great Canada Forest, refusing to admit defeat in the face of the elves, the humans were forced to accede to peace when the Revlon Empire broke into civil war, indicating that the monarch at the time was worried about the potential spillover into his nation.
