Asmodeus lead a large group of Celestials to fight against the Gods and their armies. This Revolution was unsuccessful and resulted in the creation of Devils after the fall of the revolutionary army.
This probably won't be perfect or anywhere super accurate but it'll be fun to me so
The Era when the Gods were awake
Tiamat began her war against the Gods in an effort to gain vengence against all the Gods for the death of one of her partners. Bahamet sided with the Gods to try and convince her to accept the death and calm down in exchange for punishment only being given to the God of Death. This resulted in Tiamat's banishment to the Abyssal hells.
He Who Plays With Particles sealed the doors between the various planes of existance roughly 3 centuries before The Sleeping. Some myths say this was due to his desire to stop Asmodeus from influencing his younger sibling "He Who Set The Stars In Motion" any further than he already had. It did however, have the added effect of locking out the rest of the planes from interacting causing these planes to have formed far more internal cultures in the last two and a half milennia than they once had before Planelock. Alas, this did not stop "He Who Set The Stars In Motion" later from becoming "He Who Does Not Sleep" so perhaps it was too late.
The Day The One Who Does Not Sleep put the Other Gods to sleep. Little is known about how or why this happened. Simply that it was marked by a Red Sky and is the first records of the God of Fate instead of The God of Time
