Like, as we have seen in Xayah and Rakan cinematic, when Zed failed to seperate Spirit World and Physical World, everything was in harmony again.
It makes me think that Spirit World is a realm that we can't see but always there with us. And in some places, gates of the 2 worlds get weaker. So that's why Ionia is naturally more magical and more related with nature and spirits. It is a continent that has stronger relation with Spirit World because of the weaker barrages / gates / whatever that is barrier.
If it is like that, could we have a Spirit World map?
I also like to imagine Spirit World as a generally peaciful place. Like the Ori and the Blind Forest atmosphere. There is harmony and order, but some forces are just malicious that want to break it down. (evil spirits aka demons).
Spirit World being like this would be fucking amazing IMO. That atmosphere, that peace...
