Yeah, never really got or cared about this whole Dominion thing. It does not sound like a status that I would even want, let alone work for.
It's like worrying about time travel changing the past.
Time travel either exists, and therefore someone has discovered it, either in my past, or in my future, or halfway across the observable universe from me, and already made all sorts of changes I know nothing about and can't do a thing to have changed anyway, or it doesn't exist. Either way, irrelevant to me.
Either Dominions exist, and in the last 5 million years someone in the vast unknowable universe has already become one and is writing my story anyway, and I can't even tell, let alone do nuffin' about it, or Dominions don't exist. So, whatever. Pass the milk.
I'd be amused to find out that 'Dominion' is just a buzzword invented by the various cosmic entities like the Stranger, In-Betweener, Eon, etc. to keep little people busy trying to reach some sort of informational singularity where they are filled with infinite knowledge, and just too damn overwhelmed by it all to serve as anything other than vast informational repositories for the Elders.
Ding! You have reached Dominion status! Galactus checks oven, "Oh good, another Dominion has finished baking. I look forward to browsing this new archive and then putting it on the shelf with the last 2,483 issues of Dominion Millenially to arrive..."
