There are seven large population areas of Lenga. The name of each is usually the human name for each area. Each area is not necessarily its own continent, but they are distant enough from each other to be culturaly distinct.
Dacia: Where most characters are from.
Serhanakintra : Land of the Sun and Moon. Trade is important with this region, especially spices and silk. Many scholars of this region are accused of being atheists by the Dacians - this is one of the sources of a negative ethnic stereotype of Serhanakintri by Dacians.
Il-Zehar: Land of the Midday Heat. Trade is somewhat important with this region as it is the home to most saffron growers. Also important in this area is metalworking, mathematics, engineering, and teachers of magic. Stories from explorers to Il-Zehar tell wild tales of large 'metal-men', exotic magic, and great riches.
Che-san: Land of Tea. Many in Dacia love tea and import almost all of it from Che-san. Many socities within this area are closed to outsiders. Those who travel here also call it the land of demons as these powerful creatures fight for control of this world and various off-worlds as well. It has been said that one of the powerful rulers in this region has traveled to other worlds bodily, not astrally. (If such stories can be believed.)
Ogdan: The Ogdan lands are not largely human populated, but much favored by humans. This area is named for the predominate species living there, the Ogdan. Although Ogdan are mute, they have no trouble communicating or being understood, despite the use of hand signals to 'speak'. Humans have studied the hand signals, but there appears to be little consistency in signs between each individual Ogdan.
The Ogdan are known for their artistry and metal-working. Ogdan steel is lighter and stronger than even the best Dacian steel. The Ogdan do not make armor, despite heavy bribes offered, but occasionally make swords. (Most Ogdan do not carry weapons, in times of war, an Ogdan is usally armed with either a polearm or a mace.) Ogdans are also known for their crystal work (not glass, but heavy crystal) in addition to their blue and purple dyes. Blue and purple dyes are rare in Dacia and fetch a good price. Many Ogdan trade for things made with sugar, glass items, or horses. (Ogdans did not encounter horses until the first traders arrived.)
More to come, but not much detail yet...
Ohiini: (the ii represents a long vowels as the i in 'pick' held longer)
