Religion in Sula
The main religious body of The City is the Chorus of Light. They believe the Infinite One split itself in order to create the world and seeded the stars in the night sky, each being an aspect of the Infinite and each adding to the song of Creation, even if the individual gods and demigods are believed to be enemies.
Their holy books include the story of how Xar-Nar managed to trick the other gods into arranging the Celestial Ensemble but ended up getting bored and making a mess of things, hence why some stars are in constellations and others are just scattered about, the story of how Aria taught the Aven their fabulous sky dances and the story of how Omkha rejected her place in the Celestial Ensemble to guard the Waters of Life from the emerging mortal races, and so on.
Some sceptical fellows like to point out how the Chorus just is an amalgamation and how it incorporates gods of smaller religions in order to increase its membership. However, Choralists retort that they are simply bringing together pieces of the larger divine picture.
They place a heavy emphasis on song and spectacle, their buildings are easily the biggest religious structures in The City and special masses are common. The main message behind the Chorus of Light is to take the good with the bad, even sharp and flat notes are needed for a song to work.
Priests of the Chorus usually choose to worship – or in such cases, such as church-raised orphans – are given to a particular god or goddess; they are separated via different Intonations (e.g. one Intonation for Aria and another for Omkha and so on). These different Intonations claim to bear no rivalry towards each other but there are always a few radicals who believe their god or goddess is above all others. Nevertheless, all are part of the same Canon.
Most religions outside of the Chorus are folk religions or cults and vary wildly.
