Anu and Padomay form from primordial nothingnessAnu personifies order, stasis and light. Padomay personifies chaos, change and darkness. They are equal and opposite forces to one another.
Depending on certain beliefs, Anu is described to either encompass all that exists or is just a static force incapable of consciousness
Anui-El and Sithis are birthedAfter their clash, Anu and Padomay "birthed their souls" in the form of Anui-El and Sithis.
Anui-El represents the soul of all things, whilst Sithis represents all Anui-El's limitations
The Aurbis (The Universe) is createdThe interplay/overlap between Anu and Padomay (or Anui-El and Sithis in some sources) resulted in the creation of The Aurbis, occasionally called Grey Maybe.
The Aurbis contains the Void, Aetherius, Oblivion and at its centre Mundus (which has Nirn at its centre)
Auri-El and Lorkhan are birthedThe creation of The Aurbis led to the first beings formed from the Void come to existence. Just as their fathers did, Anui-El and Sithis birthed their souls in the form of Auri-El and Lorkhan.
Auri-El is the elvish version of Akatosh, the chief god of the divines and creator of time
Lorkhan is the creator of mortals and patron to men
More et'Ada begin to formAfter the creation of time by Auri-El, the turbulent Aurbis began to stabilize and allowed for more et'Ada (Original Spirits) similar to Auri-El and Lorkhan to form.
Lorkhan tricks Aedra into creating MundusLorkhan proposed the creation of Mundus, the mortal plane, to his fellow et’Ada; a plane full of beings of the et’Ada’s creation. This split the et’Ada into the Aedra (those who helped create mundus and translates to “our ancestors”) and the Daedra (those who rejected his plan and translates to “not our ancestors”)
The Aedra began to form the mortal plane but soon realized they’d been tricked, as Lorkhan didn’t mention that they would be giving up some of their power and divinity in the process
Gods depart and Ehlnofey are createdMagnus, god of magic and architect behind Mundus soon learnt of the sacrifices needed to create the mortal plane. He abandoned his project flee back to Aetherius, tearing a hole through Oblivion which became the sun, allowing magic to flow into Mundus. The Magna Ge (other et’Ada that followed Magnus) tore smaller holes which became the stars.
Others chose to sacrifice all their power and became a mortal race, known as the Ehlnofey, who later diverged into the mortal races of the Merethic Era
