The Aurideon is the seat of power for the Iridescent Church. One of two sovereign city-states within the bounds of Hallia, the Aurideon is governed exclusively by the Church, while the rest of the Calarian government has little say. Entry is restricted for non-believers, but exceptions are frequently made when business requires it.
The Aurideon is covered in a giant crystal dome, structured to amplify the Host's aurorae overhead. Most convox in the city are headquartered here.
