Demacia and Ionia

Considering where they are on the map I'm not sure they have any relations. Demacia wouldn't go out of their way to have a political relationship with them even if they were closer, due to magic and what not, and considering they are super far apart it's possible there has been no official contact between their governments.

Demacia is very isolated so I'm not guessing they have very good relations with anybody.

And even if they have relations with Ionia, I don't think they'd be very good friends seeing as there's so much magic in Ionia.

depending on how things go I'd say they could at best be neutral. both are enemies of Noxus after all, and the whole "The Enemy of My Enemy is My Friend" thing.

ionia is actively trying to make people, magic and nature work together, so they wouldnt ally themselves with demacia since they are trying to restrict the use of magic, altough ionia is a peacefull land, they wouldnt ally with someone who's morale point of view is the thing they are trying to avoid the most

if you havent noticed, demiacia is not the great contry demacian think it is, its a contry that indoctrinate their citizen and doesnt allow people of their land to have different opinion, demacia could tolerate ionia and form an alliance if needed, but ionia wouldnt ally themselves with demacia
