Creation (This goes much farther back)

Era beginning/end

In the beginning, the universe lay empty, a vast void untouched by light or life. It was here that Order appeared, a celestial being fleeing the chaos of a collapsing universe.
  Determined to carve out a realm free from the clutches of Chaos, Order sought refuge in Ereanor's silent expanse. With a decisive gesture, Order summoned the gods forth, granting them the power to shape the fledgling cosmos. Entrusted with the monumental task of creation, the gods meticulously crafted worlds and planes, infusing them with divine essence.
  Yet, amidst their labor, Chaos lurked, drawn by the smell of creation and the allure of tearing it all down. Once it arrived with its Illithid armies, Chaos targeted Aevitâs, the god of time, disrupting the flow of time and throwing the fabric of reality into disarray.
  Recognizing the danger, Order and the gods acted swiftly, imprisoning Aevitâs within the Feywilds to tend to Runestökkr, the Tree of fate. Desperate to contain Chaos, Order imprisoned the both of them in a pocket reality, leaving the gods to navigate the cosmos alone.
 
  Undeterred, the gods continued to fight the Mindflayers. They created the Gith, alongside Dragons. The Gith were meant to be the perfect counter to the mindflayers. They fought a war spanning hundreds of thousands of years, the Gith emerging triumphant. As time passed, Chaos's corruption seeped into the divine ranks. Among them, Null, fueled by envy and ambition, plotted to seize power.
  Manipulating the gods, Null orchestrated the creation of Ereanor, a realm unlike any other. Inspired by the Githyanki, the realm was populated with new races.
