The Last War Has Ended-Sort Of. The Last War plunged the continent of Khorvaire into civil war more than a century ago, shattering the Five Nations that made up the kingdom of Galifar. Just two years ago, the war ended with the signing of the Treaty of Thronehold and the establishment of twelve recognized nations and a tenuous peace. The conflicts, the anger, and the pain of the long war remain, however, and the new nations seek every advantage as they prepare for the next war to break out on the continent.
Dragonmarked Dynasties. The great dragonmarked families are the barons of industry and commerce throughout Khorvaire and beyond. Their influence transcends political boundaries, and they remained mostly neutral during the Last War. Not technically citizens of any nation, the matriarchs and patriarchs of each house live in splendor within their enclaves and emporiums located throughout Khorvaire. These dynastic houses of commerce derive their power from dragonmarks – hereditary arcane sigils that manifest on certain individuals within the family, granting them limited but useful magical abilities associated with the trade guilds each family controls.
A Continent of Adventure. From the jungles of Q’barra to the blasted hills and valleys of the Demon Wastes, from the skyscrapers of Sham to the dinosaur-filled Talenta Plains, Eberron is a world of adventure. Adventures can draw heroes from one exotic location to another across the continent of Khorvaire.
A World of Magic. The technology of Eberron has developed not through the advance of science but by the mastery of magic. The widespread use of magic pervades life in the cities and towns. Airships and rail transport make rapid travel across the continent possible. A working class of minor mages, called magewrights, uses spells to provide energy and other necessities.
Shades of Gray. In Eberron, mortal creatures are products of culture and circumstances, rather than the direct influence of the gods. As a result, you can’t assume that a gold dragon is good or a beholder is evil; only in the case of celestials, fiends, and certain other creatures whose identity and worldview are shaped by magic (such as the curse of lycanthropy) is alignment a given.
