An ASB scenario involving Classical Mythology:
Basically, Italy and Greece in 1928 became puppetized by the gods of Classical Mythology, who led both nations on an ultranationalist path. With the Nazis rising in 1933, the three nations formed the Rome-Athens-Berlin Axis.
I'll be making two maps: One set in 1944 (the height of the war), and one set in 1968 (exactly 20 years after the war ended). Similar to the Nuremberg Trials, Italian, Greek, and Olympian (aka Classic Mythological) War criminals would end up being trialled for their war crimes. In this case, the Florence Trials.
Italy in Roman Empire purple, Greece in Mount Olympus/Realm of the Gods green, Yugoslavia in Ustase brown.
Things of note:
Greek-administered Anatolia is notably well-off compared to most occupied territories of Greece.
Switzerland is a client state of Germany and Italy, with Geneva split into a Swiss west and an Italian Provencal east. The French State exists, but is governed from Limoges instead of Vichy.
Yugoslavia is a kingdom led by Serbian fascists. Dalmatia, Herzegovina, and Montenegro are ceded to Italy, while Romania, Hungary, and Germany partition the north. Italianization is rapid in Dalmatia-Herzegovina, with over 300 thousand South Slavs displaced.
Italian and Greek Albania are moving in opposite directions. The Italians are inclined to assimilate Albanians as part of Italy, while the Hellenist Greeks want to plunder Albanian culture altogether.
The Bulgarians are suffering a genocide on par with OTL Poland. Macedonia and Northern Thrace are akin to the Reichsgau Warthenland, while northern Bulgaria is more or less the Greek version of the General Government. Sofía and northwestern Bulgaria are annexed by Yugoslavia (think of it as the Bialystok region after the Belarusian SSR annexed it).
