The autonomous Crossbell State (クロスベル自治州 Kurosuberu Jichishuu?) is a landlocked, self-governing state with a population of 500,000, it is located in western Zemuria. It is bordered by Erebonian Empire and Republic of Calvard on the site of former violent territorial disputes and became an independent state seventy years ago.
The heart of the state, Crossbell City, has become the leading trading center of the continent, experiencing great urban growth. It has also become a relay point for the railroad and airship networks linking the Empire and Republic. Tensions had increased over the past several years as the major powers conducted large-scale military exercises, though they have been greatly reduced since Liberl assisted in the creation of a treaty two years ago. As a result, people and money have flowed into Crossbell, bringing with them skyscrapers, Orbal Cars, an Orbal Power Network and a new infrastructure to support them.
- Crossbell City: Lying in the heart of Crossbell State, it is the capital city of the State.
- Armorica Village: A village in the northeast which engages in farming and beekeeping. Boasts ancient roadways, abundant water, vast flower gardens and beautiful scenery. People tired of the bustle of the city come here to relax so the village has a thriving tourism industry. It can be reached from the city in two hours by Orbal Bus.
- Mainz Town: A village in the mountainous northwest where Sepith is mined. Crossbell has long been famous for the high quality of Sepith that it produced. In recent years its reputation has been overshadowed by Crossbell's emergence as a trading power. Despite output decreasing, there are still many buyers from foreign countries who come here to purchase Sepith directly from the source.
