Cathedrals are large ornate churches built to serve the Christian faith. Within fictional settings, however, cathedrals have become somewhat disassociated from their real world purpose and fictional cathedrals (or at least structures that mimic them in form and function) are often used to honor other fictional gods or serve other fictional religions unique to a fictional world. They are often home to fictional religious factions and may be an important aspect to a theocratic state. Fictional cathedrals are often depicted as massive stone structures, with various wings and chambers dedicated to prayer, services, and housing members of a religious organization. They are commonly built atop sprawling catacombs or crypts.
