here is my understanding of the geography of the current relevant countries
theres 3 major continents in this isekai, west center and east
center continent, aka 1st Civilization Area (named millishient continent)
emor kingdom, dragonkin folks that did the future sight divination thing
milshial kingdom, the ones actually holding the conference and the ones about to be attacked at the end of the chapter
west continent, aka 2nd Civilization Area (named mu continent)
Mu kingdom, we know these guys right, they also border leifor
leifor & paganda, paganda killed gra valkas empire envoys so the gra valkas retaliated by destroying and occupying paganda then continued to destroy and occupy leifor
gra valkas to the west/left of mu continent
gra valkas, newly emerged isekaied country, a WW2 era level civilization that just got isekaied from another world called YGGD, very aggressive country that seems to be the bad guys this arc
east continent, aka 3rd Civilization Area (named philades continent)
former parpardia empire, that Japan won the war against and uis now rebuilding under the morals and leadership of our civilized ways
Japan is located even more east of the philades continent in the middle of nowhere kinda
