The Eternal cities didn’t exist before Marika’s Ascension to God hood

So I came to this realization after playing SOTE, there are quite literally no eternal cities in the shadow lands; presumably that’s because they didn’t come to be until after Marika became a god.

I’m not sure what lore implications this has but it’s an interesting little thought. If speculation on the Gloam-Eyed queen being related to the Nox is accurate that would mean she didn’t exist until after Marika became a god; which leaves a few questions.

What are everyone’s thoughts and opinions?
