It is. It's a reenactment of the creation of the universe, and powerful events will be forever imitating it.
From the Anuad that no one ever reads correctly:
The first ones were brothers: Anu and Padomay. They came into the Void, and Time began.
As Anu and Padomay wandered the Void, the interplay of Light and Darkness created Nir. Both Anu and Padomay were amazed and delighted with her appearance, but she loved Anu, and Padomay retreated from them in bitterness.
Nir became pregnant, but before she gave birth, Padomay returned, professing his love for Nir. She told him that she loved only Anu, and Padomay beat her in rage. Anu returned, fought Padomay, and cast him outside Time.
Two brothers, a woman to create discord, and one kills the other. (or the rebel betrays)
Akatosh and Lorkhan struggling over creation.
(The witness is elusive and mysterious, and is more often found in mortal form on Mundus. You could posit that the inhabitants of the world are the ones witnessing this event and its repercussions.)
Anu and Padomay are both pulled out of time in the end because from the One came two brothers, who became four, who became the world.
