THE TWIST AT THE END OF THE DARK AGES – IS IT A SEQUEL? – From /r/Doom

Here’s what we know so far…

Doom Timeline: Void -> Jekkad -> Urdak -> Human dimension 1(Doom 1 – Doom 64) -> Argent D’Nur (Dark Ages) -> Doom 2016 -> Doom Eternal

So I got a couple questions…

1. Why do the Demons in Doom the Dark Ages look so different compared to the Demons that came in Doom 1 and 2016? If Doom 1 took place before the Dark Ages then the Demons that came from Hell should have looked like the ones from Doom 1, right?

2. Did Human life originate from Argent d’nur in every single human dimension?

3. If 2 is correct, does that mean an Argent D’nur is created at the start of every single new human dimension that is created? And if that’s a yes..

Could it be possible that Doom the Dark Ages is not a prequel, but actually a sequel, and that this is just a new human dimension created since the last one Doomguy completely fucked up? Is this what they mean by an Doom “Eternal”? That this is an endless cycle of suffering, and in order for it to stop, the true God above Davoth must be destroyed?
