- Main article: Crossbell#History
Located historically at the convergence point between the Erebonian Empire and Calvard Republic, the city has been site of an extraordinary number of battles between various groups of people, notably the Erebonian Empire and Calvard even before the republic era since the region has been changing hand for more than five times over the past 1200 years.
With approximately 500,000 inhabitants, Crossbell City is one of the largest cities in Zemuria. It serves as the continent's most important centre of commerce. In addition to being a key station on the Transcontinental Railroad, the city is home to a major international airport. International Bank of Crossbell is the largest financial corporate in the west Zemuria. Its government was initially run from Governmental District until the completion of Orchis Tower where most administrative activities is later transferred there.
Underneath the city runs a large, excavated space known as the Geofront. It was designed to facilitate infrastructures for water supply, sewerage and waste disposal. It was later expanded with the Orbal Network and numerous other equipment. The Geofront itself, however, remains unfinished.
The city never formally implemented laws to crack down on spies. As a result, the city's back-alleys serve as a hotbed for intelligence operatives from Erebonia and Calvard as well as crime syndicates and mafia. The city is therefore also known as the City of Sin.
Crossbell City consists of eleven districts:
- Central Square
- Station Street
- Governmental District
- Waterfront Area
- Entertainment District
- The East Street
- The West Street
- Residential Street
- Back Street
- Orchis Tower
