Recent History of Eberron

As the campaign begins, Eberron emerges from a long and devastating war. The nations of the continent of Khorvaire were once part of a great kingdom of legend, the mighty kingdom of Galifar. When King Jarot died, his five heirs, each in command of one of the Five Nations that comprised the kingdom, refused to bow to tradition. Instead of allowing the eldest son to take the crown, the siblings rallied their vassals and each vied to take control of the kingdom. Over time, this decades-long conflict became known as the Last War, for everyone imagined that when it finally ended the taste for bloodshed and battle would be wiped from the face of Khorvaire.
The Last War continued for more than a century, with each of the Five Nations alternately fighting against or alongside one or more of the others as alliances and animosities shifted as fast as the wind in the Shargon Straits. In time, other nations formed as deals were made and opportunities presented themselves. After 102 years of fighting, the leaders of the recognized nations of Khorvaire (which now numbered twelve) met at the ancient capital of Galifar to draft a peace. With the signing of the Treaty of Thronehold, the Last War came to an end.
Today, the nations of Khorvaire seek to rebuild and prosper as the new peace spreads across the land. While technically at peace, the nations continue to vie for economic and political supremacy. Minor skirmishes break out every so often, especially in the more remote sections of the continent and on the most hotly contested borders. Espionage and sabotage are the preferred method of diplomacy, as the nations engage in trade and discussion in public while working intrigues and double-crosses in the shadows.
