Xanadu

Xanadu (上都, for "Upper Capital") is one of the six main territories under the Kingdom of Shambala's rule, which are collectively known as the "Níngjìng Màntuóluó Wǔchóngzòu" (宁静曼陀罗五重奏, Pinyin for "Tranquil Mandala Quintet"); Xanadu is alternatively referred to as the "Vacation Lands" (休暇国, Kyūka-kuni) due to it being used for times of relaxation and contemplation, being one of the most popular places in the Yuanren.

Trivia

 * was the capital of Kublai Khan's Yuan dynasty in China, before he decided to move his throne to the Jin dynasty capital of Zhōngdū; it served as a "kingdom of paradise" and made out to be the equivalent of Shangri-La. Rather fitting, as Xanadu is a resort in this incarnation.
