The long, undulating bodies of these serpentine dragons roll and bend with scales the color of the ocean\xe2\x80\x99s waves. \n'b' Dragons are an integral part of the mythology of Asia, though they are quite different from the winged dragons known in the Western mythology. Some are benevolent and others sinister, but while their appearance is different from Western dragons they are equally capable of the savage rapacity and legendary greed of their chromatic cousins and the stern and aloof devotion to goodness of their metallic kin. Like most monsters, imperial dragons have an assigned typical alignment, but they are highly individualistic and much more likely to have an alignment that varies from the typical than would be true for metallic or chromatic dragons. \n'b' Imperial dragons, sometimes termed dragons of the celestial host, in the \xe2\x80\x9cdragon empires\xe2\x80\x9d are serpentine agents of cosmic balance, though some of them are not above sowing chaos and discord for their own gain. Imperial dragons differ in appearance from the more commonly known chromatic and metallic dragons, possessing a long serpentine body. Most lack wings but can fly gracefully through supernatural means. \n'b' All imperial dragons have large antlers, some sweeping back in delicate curves and others thrust forward to gore their foes. \n'b' Like all dragons, imperial dragons can breathe potent torrents of elemental force, and many can cast spells and perform other supernatural feats. Additionally, all can magically transform themselves into a humanoid shape. \n'b'  Imperial Entanglements . Imperial dragons are defenders of ancient lands and protectors of cosmic balance. They take a much more active role in humanoid societies than their metallic or chromatic kin, to such a degree that the kingdoms of in lands they are known sometimes refer to themselves as \xe2\x80\x9cdragon empires.\xe2\x80\x9d They are active in times of social upheaval, and may be sought out for their wisdom or aid. Imperial dragons are seen by humanoids as either benevolent guardians or vile threats depending on their type. Some imperial families trace their bloodlines to the semi-divine dragon-emperors of old or still rely on the counsel of living dragons or, in rare cases, ask a dragon to rule as their wise sovereign. \n'b'  Mandate of Heaven . More so than any other dragons, imperial dragons are closely tied to the religious beliefs of their native lands. Imperial dragons are often associated with divinity, whether as guardians or emissaries of a god, as the representation of a god, or as a deity themselves. It is said that imperial dragons inhabited their lands in an Age of Dragons, long before other races arose there, and were charged by the gods to safeguard the land in anticipation of humanity\xe2\x80\x99s arrival. Some of the gods themselves may in fact be incredibly powerful dragons transcended into immortality, and each of the five species of imperial dragon is represented as a constellation. \n'b'  Adult Dragons . The imperial dragons presented in this book are all adults. As agents of the highest deities, young dragons sometimes wander in mortal lands before they ascend, though many are kept safe in the realms of the divine until they reach maturity and complete their training. Older dragons may likewise \xe2\x80\x9cgraduate\xe2\x80\x9d from their status and join the celestial bureaucracy, while others roam freely to live as they wish. If you wish to extend the lifespans of imperial dragons into youth or old age like other true dragons, you can adjust their abilities up or down in a manner similar to other dragons with equivalent Challenge levels.'
