[@Rare]It's totally up to you, but so far we have the following characters in the following cities and countries.
M - Kai - Honolulu Hawaii, USA
F - Sydney - New York New York, USA 
M - Foxtrot - Portsmouth, England
F - Christina - Manila, Philippines
F - Dalia - ??? ,Israel
M - Jorn - Copenhagen, Denmark  
M - Steven - Sydney, Australia 

Where in America exactly?

I think it would be best if we have a lot of diversity in the story so best avoid having two characters in the same country or at least city to emphasize the drama and need for them to meet. At the end it is up to you and how you would like to run your character.

[@MMGiru] Where exactly in Israel is Dalia?

[@iSuspect] BTW what's our timeline? I believe I remember you saying at some point that it's been a week or a few days since they were "birthed"? I figure this'll be in the first post, but I wanted to ask anyway.
