Pretty good history check from Tereze! Long lore drop inbound
Tereze remembers the ancient family library at her family's estate and reading about the History of Exandria as a young adult. While it is still up for debate and often disputed by many scholars, the most widely accepted creation myth of Exandria is this. The world of Exandria was first a chaotic ball of wild elements, storms and fire raged on ceaselessly, and this chaotic rock was ruled by the Primordials-- elemental beings of near-deific power. But Exandria was devoid of life, just roiling water, earth, fire, and air.
The Creators (all of the gods except the Raven Queen and Vecna, who were mortals that joined the pantheon later on) arrived to Exandria and breathed life into the world, creating the first elves, dwarves, humans, and so on. Their creations tried to live on Exandria, but the Primordials and their elemental chaos made their lives short and dangerous, which saddened all of the Creators. There was intense debate amongst the Creators, but eventually the majority of them decided to gift their creations magic. This helped in their fight against the Primordials, but it wasn't enough. From there, the gods split into two camps.
The Prime Deities fought alongside their creations to destroy the Primordials and tame the world for their creations' safety.
But the Betrayer Gods, as they would soon come to be known, frustrated by their losses, gave up and tried to abandon their creations. Some with mad with grief and loss, and others gave in to the temptations of the Lower Planes such as the Abyss and the Nine Hells. They returned to Exandria and fought alongside the Primordials against their creations and the Prime Deities. The Prime Deities were eventually victorious and sealed away their betrayer brethren along with the Primordials.
Humanoid society thrived in the following centuries, with the Prime Deities walking across Exandria at their side. This led to the grand Age of Arcanum, where magic became mundane and everywhere, often referred to as Exandria's golden age. However, humanoids became so powerful as to be able to fight the gods, and some tried to usurp them.
In the process, the Betrayer Gods were unleashed once again, thus beginning the Calamity, the second war on Exandria between the Prime Deities and the Betrayer Gods. The Prime Deities were victorious once again, but not before centuries of untold death and destruction were wrought against Exandria, with over 2/3 of the world's population wiped out.
Regretting the chaos their presence has caused Exandria, the Prime Deities locked themselves and their brethren behind the Divine Gate, which prevents the entry of any god to the Prime Material Plane.
There are some variations, such as followers of the believe that the young, formless, curious Luxon was the first to arrive to Exandria in search of an understanding of itself. And some even believe that the Luxon gave birth to the Primordials and shaped the elemental chaos of Exandria's first age.
