The relations between Celesteville and Rhinoland have occasionally flared into war, although it is usually just a statement and peace is restored before much damage or casualties are suffered.

Some stories feature the two countries working together against common threats, such as when the area is infiltrated by poachers, and the two will help each other during times of need or crisis.

Known citizens of Celesteville include: By Babar's decrees, a number of public institutions, schools, hospitals, parks, museums, libraries, an opera house, and other works of infrastructure have been built.

The kingdom has a rail line, and Celesteville itself is connected to a large body of water (presumably a sea or ocean), making it a port city.

Vehicle traffic is common in the kingdom, especially Celesteville, but most of the residents still seem to prefer to travel on foot or by bicycle, since many of the city's amenities seem to be fairly close to each other.

The Royal Guard acts as both the Kingdom's Royal Guard and occasionally functions as Celesteville's police force likely because of crime being a rarity in the kingdom and are often called in to defend the palace and Celesteville from attack or theft by the likes of Prospero and Blacktrunk.
