The culture of the Atlian Empire itself is a mixture of its three main cultures: Northeastern Mexican, Acadian and Hrafnarfjallian. Not having a specific culture does not stop the citizens of the empire from interacting and generating culture.

In the Kingdom of Atlia, one of the main holidays is the Day of the Dead, where in Nova Atlium an altar is created annually in memory of the faithful deceased of the imperial family, and the population is invited to create their own, or to join to the one created in the capital, where Pan de Muerto and hot chocolate are shared.

In Atlia it is also common among its citizens to have "presentation parties" where attendees create slide presentations, presenting any topic, and attendees are expected to do the same. Generally this dynamic is accompanied by dinner.

In the Kingdom of the Southern Star, the Elizaburian Cultural Day is of notoriety, as it highlights the qualities of the Elizaburian culture, originating from the House of Dearmad-Otillicaries and transmitted to the nations in personal union with it.
