Crossbell State (クロスベル自治州 Kurosuberu Jichishuu?) is a landlocked, self-governed autonomous state in the Trails Universe. It is the main setting of the Zero no Kiseki/Ao no Kiseki duology, and central location of The Legend of Heroes: Akatsuki no Kiseki. It is located in western Zemuria, with a population of 500,000.
Bordered between the Erebonian Empire and Calvard Republic, the state and its domestic sovereignty was formed seventy years ago prior to the Trails series. It has been the centre between violent international disputes for territorial claim by the Empire and the Republic.
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 brought out the "Non-Agression 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: The main capital, and "heart 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.
Due to international affairs between the Empire and Republic, the politics were very unstable where corruption grew in and out of the government. This lead to the many distrust of its citizens, where they prefer the Bracer Guild better as they prioritize citizen's needs first.
The autonomous state relies on the police force and guardian force for national security. But the low politics makes them susceptible to corruption, whereas supporting the mafia and crime syndicates in the underground.
