Auralios is the great city of Araxis, which is built on the first moon, Volaris. The city is inhabited by the Celestial Gods who have taken on form, the Pure Born (a race of immortal demigods), and Dwarf craftsmen led by Maurak who were brought to Volaris in order to build the city. Auralios is named after Auros, the sun god. It is the wonder of the age (and perhaps any age of the world), until it is conquered by Lornak the god of Death with his allies the Darkness Demons.
The creation of Auralios is told in the story "The People of Volaris"
The demise of the city is told in "But Death will Follow"
