My point still stands:

Creating a plane(t) takes power. Each Et'Ada is a plane. So, to create all of those (Who are as numerous as the stars above) lots of power was needed. You cannot avoid the fact that that power had to come from Anu and Padomay. And also, how did Aetherius and Oblivion come into existence if Padomay and Anu were the only things ever to exist, in the very beginning? So, not only did their blood (In other words, their life force or essence) create the Et'Ada, it seemingly also created a whole new universe. All that must've required two things: A, a damn lot of matter (Speaking slightly scientifically here) and B, a damn lot of power.

If you ask me, Sithis and Anu bled to death. Their corpses are likely what formed the respective dimensions of Oblivion and Aetherius. And their souls? Well, Sthis' soul still exists (And Anu's likely does too). AKA, the void.
