[@TheWindel] But who would she send if everyone's at war, and there are no neutral parties except people who are even worse than the factions? That would just establish someone else having the capacity. Someone had to go to each factions respective messenger groups, arrange things, and then transport goods across borders.

I'd also like to mention that Miyu visiting the Machina controlled lands is literally in her bio.

Actually, I have a great idea for the someone. If only there was someone Miyu knew, who's already established as part of canon, who could fit in literally anywhere. Who'd even make a great bartender due to their ability to summon whatever you want. Yay for ideas!
