I'd like to collect all the info we actually have on Earth C, as a starting point for writing stories there. I'm not even sure where the Four Kingdoms are in relation to each other, or how much the geography still resembles our Earth. It's implied that hopping from one capital city to another isn't a big deal, though that could just be down to God-tiers not knowing the struggles of the little consort.
On the other hand, us not knowing means you can make up pretty much anything, and the Well Ackchually-ers won't have any way to well-ackchually it.
