Spectronightism

Spectronightism is the belief in the 8 major gods, Spectro, the goddess of light, Celestia, the goddess of the stars and night, Solaris, the god of the sun, Luna, the god of the moon, and the 4 elementals, Fire, Water, Earth, and air. They have a set of 2 holy books, called the Cosminomicron. Book 1 is called "Dawn", and Book 2 is called "Epoch". There is also a 9th, malevolent god named Chaos, who is trapped in the Abyss (the void), a space between the Surface (the overworld) and the Core (the nether). There are no mentions of the End in Spectronightism.

Beliefs
Spectronightists believe in 2 major events, the First Reckoning, and the Second Reckoning. The First Reckoning took place millenia ago. It was when Chaos escaped the Abyss, (there was no bedrock at the time), but 4 prophets warned the kingdoms, so they sent 7 magicians, (they had magic back then), and they drove Chaos into the Abyss, and sealed him by gathering everyone's magic and soldifying it into the bedrock that covers the roof of the Core, and bottom of the Surface.

Second Reckoning
The Second Reckoning is the second escape of Chaos. It is said that Chaos will lay waste to the land, and only those who truly believe will be protected by Spectro. After the world is destroyed, it is said they will "ascend", by dying, becoming one with the nothingness, and allowing Chaos to stop existing. Some also suggest they will come back as gods once Chaos is defeated, but this is not said in Book 2: Epoch.

Extras
Spectronightism ceased to exist, with only Ravology, who is named after one of the Prophets, practicing the religion. He is attempting to get more people into Spectronightism.
