In all seriousness, Asgard is a dimension.
I had forgotten the initial assertion being made here, that Serpent and Gorr were universal beings.
I don't think Factions statements regarding Asgard being a fully fledged universe in any way make them a universal power. It's a possibility given the wording, but it's not really consistent with earlier or subsequent portrayals.
Edit: What does it being a dimension entail, who knows...Franklin's counter-earth was almost a universe, but still a dimension and still contained within 616.
