The kingdom of Avoria lies in the high mountains of Mythralis, where the peaks rise above the clouds. Here, among the majestic peaks and windswept plateaus, live anthropomorphic flying creatures. The kingdom's inhabitants, known as Aereons, have developed cities that span the mountains and the skies, building suspended structures and villages perched atop giant trees. The main cities are connected by suspension bridges and aerial transport, utilizing the Aereons' innate flight abilities.

The Aereons, descendants of the avian creatures of Mythralis, developed anthropomorphic features that combined bird features with the human form. Their wings, plumage, and keen eyes were clear signs of their heritage.

Over time, the Aereons built the kingdom of Avoria in the high mountains and among the clouds, creating aerial cities that span the highest peaks and summits. Their culture developed around the worship of the sky and celestial deities.
