Ok guys I need a bit of a help, because the moving between nations are kind of confusing. Which exact order should I visit the nations to get everything? The walkthrough is not helpful in this. Saying visit Fernia first but then you get locked out of Necrosia etc. A clarification/clear travel order to nation1->2->3 would be pretty helpful, I already wasted 2 hours and I'm finding my mood to play diminishing. Feedback is appreciated!
Here's the order I found to be best with this latest update:
Ashtera -> Yalen -> Nocverchis -> Eldrien -> Fernia -> Dir-Klou -> Necrosia -> Geinvrik -> Kemeq -> Syqua.
It used to be visit the nations in the chronological order in which they were released with each update, but Zone 2 and Zone 3 threw a wrench into that system. If I remember correctly the nations were released in this order with each subsequent update:
Ashtera -> Yalen -> Nocverchis -> Eldrien -> Fernia -> Necrosia -> Dir-Klou -> Kemeq -> Geinvrik -> Syqua.
You can even see this release order in the gallery since there is a girl(s) associated with every nation. I can't recall for sure, but it might be that Necrosia was originally bigger in previous updates and got split into two separate nations after the fact. That being Dir-Klou for the north half and Necrosia in the south half. I don't have any of the older updates so I can't confirm.
To answer your question though, you will be able to visit Necrosia after you go through Dir-Klou, since you can only travel to neighboring nations. That doesn't really work in Zone 3 since Siann has not been developed, so you can skip around. Once the game is fully developed and all nations are released, this order will change again. One thing to note is you can't revisit any nations and if you skip a nation in a previous zone, you can't go back. So finish all nations in Zone 1 before moving on to Zone 2. You can see what zone each nation belongs to in the Map in Nulkan's tent. The guide is pretty good for what order you should complete nations in with the exception of Dir-Klou and Necrosia.
