It would be really great to have a map, but this timeline is very enjoyable and interesting, so supplemental material doesn't even to be needed
Well, it will get to that point eventually, but basically, the Gadol-Gebel Carthaginians do end up being collections of Kingdoms and Aristocratic Republics spread around North and Central America, united by their shared Kanaani culture and religion, but just like Europe, they still have bloody wars between them as well.
The Carthaginians refers to South American civilization as Quechuans, since the Andean Civilizations being the most well organized and live in easily defensible areas that allows them to survive the initial bouts of Plague that practically made native Mesoamerican civilizations being easy prey to Carthaginian refugee-colonists. The early tech exchange and early introduction of Horses and Pigs also transform the Andean civilization from being limited to mountain range IOTL into being all over South America (to the point the references of Quechuan Pirates).
At the Frozen North, the Viking settlements at Greenland and Northeast Canada actually survived somewhat due to trade and raids with the Carthaginian States that, despite being often hostile with each others, the better Agriculture of the Carthaginians made the American Vikings able to survive long term settlement there. Of course, Carthaginians did confuse them with the Inuits (up to calling them Nunawia). Of course, Greenland ITTL still being considered as scamland in Europe, so the Christianized Nordic Kings end up thinking that those Pagan settlers must be already dead long ago... But they would be in for a surprise when worshippers of the Old Gods now have Carthaginian tech (due to trade and or raids), and might decide that helping the Southerlings against Christians would be better way to go.
Basically the Medieval Europeans will clutch their Bible for their worst nightmares turned out to be true.
