In the Successor States of Rega, yearly competitions are held in each country in honor of the gods, including all the ancient Greco-Roman sports, as well as drama competitions, music competitions, philosophical debates, and more. Once every four years, the nations send all their best and brightest to the Great Coliseum in the city of Aulasaris in Southern Theudonia, near the location the ancient Regans once believed was the mountain of the gods. They later realized the mountain was extra-planar, but the earthly mountain is still a holy site.
