Joan of Arc Castle is located in the northeast of Langsande County, surrounded by crescent-shaped mountains, bordering Mande County to the east and North County to the southeast.
With the presence of the canal, Joan of Arc Castle can connect to the tributaries of the Ibe River and Nao'an River.
Timber and minerals from Mande and North Counties in the east can be brought to Joan of Arc Castle via land routes, while daily necessities and food from the west can be transported to Joan of Arc Castle via water routes.
The Ibe River flows south, passing through the forty thousand hectares of farmland in the Ibe Plain, providing precious water resources for the local farmers.
On the Ibe Plain, over sixty percent of the knights are Leia people and Falan people.
Although they were born in the Thousand River Valley, it's rare for them to marry the local nobility; usually, Falan people marry Falan people, Leia people marry Leia people, and Kush people marry Kush people.
