Emperor Yao

Emperor Yao (simplified Chinese: 尧; traditional Chinese: 堯; pinyin: Yáo; traditionally c. 2356 – 2255 BC) was a legendary Chinese ruler, according to various sources, one of the Three Sovereigns and the Five Emperors.

Ancestry and early life

Yao's ancestral name (姓) is Yi Qi (伊祁) or Qi (祁), clan name is Taotang (陶唐), given name is Fangxun (放勳), as the second son to Emperor Ku and Qingdu (慶都). He is also known as Tang Yao (唐堯).

Yao's mother has been worshipped as the goddess Yao-mu.

Legacy

Often extolled as the morally perfect and intelligent sage-king, Yao's benevolence and diligence served as a model to future Chinese monarchs and emperors. Early Chinese often speak of Yao, Shun and Yu the Great as historical figures, and contemporary historians believed they may represent leader-chiefs of allied tribes who established a unified and hierarchical system of government in a transition period to the patriarchal feudal society. In the Classic of History one of the Five Classics, the initial chapters deals with Yao, Shun and Yu.

Yao people

The Yao nationality (its great majority branch is also known as Mien; Traditional Chinese: 瑤族, Simplified Chinese: 瑶族, Pinyin: Yáo zú; Vietnamese: người Dao) is a government classification for various minorities in China. They form one of the 55 ethnic minority groups officially recognized by the People's Republic of China, where they reside in the mountainous terrain of the southwest and south.

History

Early history

The origins of the Yao can be traced back 2,000 years ago, starting in Hunan Province. The Yao and Miao people were among the rebels during the Miao Rebellions against the Ming dynasty. As the Han Chinese expanded in southern China, the Yao retreated into the highlands between Hunan and Guizhou to the north and Guangdong and Guangxi to the south, and stretching into eastern Yunnan. Around 1890 the Guangdong government started taking action against Yao in northwestern Guangdong.

Fictional character biography

Sage's exact country of origin remains unrevealed, but she claims to have come from a war-torn region. By the time she reaches young adulthood, she is living by herself in Afghanistan. Although she tries to keep out of the conflicts between the rebels and the government, she is willing to use her guns and other weapons on anything that poses a threat. One day, she feels called to a cave which is considered haunted by the locals. She hears a voice in her head that guides her deeper into the cavern, where she finds Charles Xavier, who is trapped underneath a pile of debris. His legs have been crushed during his battle with the alien Lucifer. Xavier senses that Sage is a mutant, and explains to her what her abilities mean. Sage says that this was about the same time as he located Beast, but in other accounts he found Sage first.
