Dantrian Complex was a federation of several countries in the west of the Continent, consisting of Western Dantria, Central Dantria, Wunnah and Land. Its trading, political and military center was the city of Tavoe, which later became part of what was known as the Diamond, a group of four major dantrian cities: Tavoe, Kalchinge, Walneer and Gungon.
Since most records of the Western Dantrian Civilization have been lost, historians have only a very limited amount of documents that describe the workings of the federation. It was bound by diplomatic and trade agreements, each country had a representation in all other countries of the Complex, usually in the form of an embassy, but also had representatives in some of its governing bodies, specifically those that would deal with matters of international affairs.
Dantrian Complex was able to spread its influence far to the east and form what was briefly known as the Eastern Dantrian Civilization. After the downfall of the Western Dantrian Civilization, its remnants in the east became the only tangible link to centuries worth of progress. Root Tongue is considered to be one of those links.
