15 degrees north to the Equator, to a virgin Earth
The Caribbean is locked into an interesting situation, one that closely resembles the old "Concert of Europe." No one power really dominates, and if one begins to all the others will team up against it. Colombia is the leading power of them all, beginning with the largest population, along with bringing Panama and Ecuador into the fold, has allowed them to be the closest thing that the region has to a superpower. Venezuela and France are the next most powerful states, who in contrast to Colombia rely more on their navies and overseas expansion. The two have fought over Hispaniola, Cuba, the Antilles, and now they fight in the Pyrenees, as Venezuelan settlers spill over into French claimed land. Sparce Brazil is slowly reclaiming their old country, one village at a time, and many a pioneer state have set up shop in what once was Mexico. One state that is of note is "New Tobago" in Louisiana, An ex-colony of Trinidad and Tobago that fancies itself the successor to the United States, and is growing quite rapidly.
Much of Western and Central Africa, reliant on import of food and fertilizer, fell into complete and utter anarchy after the warp. and the region has since been split into many small states. Much of the region is still balkanized and violent, but islands of stability have emerged. Fangland, Oduduwa, Biafra, Ghana, Senegal, Dahomey, Sokoto, and Uganda, just to name a few. These countries have been flexing their muscles more and more on the international stage, and this trend will only continue. Many fled north or south to escape the chaos, and trade across the Sahara is extremely lucrative. The Venezuelans even went so far as to establish a nation for these refugees in the "Moorish Republic", which is totally not just a place where they can throw incoming Muslims so the local administration in Seville doesn't have to deal with them, what would give you that idea?
In Eastern Africa, things were much more stable, at least relatively. Some outlying regions did break off from Ethiopia, and Somalian unity fell apart completely, but there was not a large famine and die off at least, so that's a plus. The Ethiopians rebuilt the Suez and settled Egypt and the Holy Land, and those regions have since gained a status like the dominions of the British Empire of old, thanks to their distance from Addis Ababa.
India was left with only its far southern provinces. Some of the wealthiest and most stable regions, but also the most culturally distinct and strong histories of independence. Unity was maintained by keeping a federal structure and playing off Pan-Indianism. India is among the premier powers of the Indian Ocean.
Indonesia was not able to handle the warp, and broke into many regions. The Riau Islands and West Kalimantan ended up joining Malaysia, East Kalimantan, the Moluccas, Aceh, and Sulawesi went their own separate ways, and only North Sumatra and Riau remained. Malaysia is the most powerful nation here, settling Borneo and Java has allowed their population to explode, and already being relatively rich has allowed them to be one of most powerful nations on earth. But it is hard to throw one's weight around when those around you are almost as heavy as you. Manila, Ho Chi Minh City, Bangkok, and Pondichery are all nearly as powerful as Kuala Lumpur, just to list a few.
The Pacific Island nations don't really want to unite, but in most ways they already have. They operate with basically one foreign policy, and share one common military. They even share their colonies. The only exception is Guam, which fancies itself the successor to the USA, and is settling Hawaii on its own.
Halfway done!
