Pyrrhia

Pyrrhia is the setting for all of the books. It is an island continent with highly varied geographical regions, shaped like a sitting dragon, and is home to the seven tribes of dragons.
Geography
There appears to be a large mountain range that runs roughly down the center of the entire continent. This range divides the continent into eastern and western parts. To the far west is desert, and to the northwest, icy wastes and glaciers. At the southeast corner, there is a lush and large jungle, bordered by swampland that is fed by the Diamond Spray River meeting the sea at Diamond Spray Delta. The northeast corner is full of mountains. At the extreme eastern side, a small chain of islands forms the "tail" of the "dragon." This section is known as "The Bay of a Thousand Scales."
Flora and Fauna
The flora of Pyrrhia resembles much of that of other parts of the earth, according to the geographical regions. For example, in the jungle, there are jungle plants that resemble those that grow in areas such as the Congo or Amazon.
The dominant life form on Pyrrhia are the dragons, of which there appear to be seven types. One step down from the dragons are the Scavengers,(humans) a bipedal, terrestrial hominid with some semblance of social structure and the ability to manufacture tools/weapons.They controled Pyrrhia until the scorching. Many terrestrial animals, including those that are domesticated such as cows and pigs, also appear to inhabit the land, and serve as prey for the dominant life forms.
Tribes
There are 7 dragon tribes Mudwings,Sandwings,Icewings,Rainwings,Seawings,Skywings and Nightwings.
