the story of Pandaria Emperor Shaohao here is the story:
The One-Way Journey
The time was ten thousand years ago, maybe more. Back then, the Well of Eternity was still there, and Kalimdor was still the Land of Eternal Starlight. The dynasty of Pandaren of Pandaria had lasted for years and generations that no one could tell.
The empire of Pandaren was built upon their overthrowing of the slavery of the Mogu. But still, it took a lot of efforts to remain peaceful with all the other strong and even aggressive races, which was a hard burden for the emperors of Pandaren.
Pandaren had great faith in Shao Hao, the crown prince, that he would be a leader of great deeds. The crown prince took training at Tian Monastery, which endowed him of the top-notch skills of a monk. Domestically he was benevolent to his people. Diplomatically he allied with other races - Jinyu, Hozen, Grummle and Yaungol - so they could make peace with each other, excluding the Mantid and the Mogu. He also shared a profound bond with the Monkey King, the leader of Hozen.
After crowning, he was referred as Emperor Shao Hao.
According to the old tradition, every new emperor needed to visit the Jinyu elder at Jade Forest who possessed the mystic power of fortune-telling by listening to the words of water. However, what was told to Shao Hao was cruelty and terror beyond his imagination.
Night elves would summon the Burning Legion, who would devour everything of Kalimdor, including Pandaria.
From that moment, the newly crowned Emperor Shao Hao realized his destiny. The throne was no longer an easy task for him. He had to search through his whole life with difficulties to fulfill it. All the glories and fortune of an emperor meant nothing to him. He had to set out immediately on the journey of the salvation of Pandaria.
This journey would be of all pains and no happiness. Should he fail, it would be the end of all.
Monkey King and the Sha
Many roads did Emperor Shao Hao took, many people did he counsel with. In this tedious and fruitless journey which seemed endless, he came to realize that the wisdom of the Celestials was essential to the puzzles. By himself he climbed up Mount Neverest, the highest summit of Azeroth in order to seek the counsel of Yu’lon, the Jade Serpent. Yu’lon did not seem to disappoint him. Shao Hao seemed to find a way to save everything – he was required to free all the burdens upon his shoulders, cleanse his body and soul, so he could be the one with the land.
But the wisdom of the Jade Serpent confused Emperor Shao Hao. What were the burdens that he needed to let go? How could he purify himself? And which was the way to be the one with the land? All these questions puzzled Shao Hao. No zen could help him to discover the secrets within.
Maybe it finally came down to his incapability? How did such an incompetent emperor deserve his jade throne? The frustrations and hopelessness depressed him. All the negative emotions became heavy burdens crawling on his shoulders. He felt like he was about to succumb.
Witnessing his bosom friend in great doubt, the Monkey King tried his best to help. He came to Jade Forest to whittle a strange magic visage out of bamboo in order to please Emperor Shao Hao. But the unexpected happened. The doubt of Shao Hao was absorbed into the mask, his doubt no longer linger. Yet another unexpected thing happened. After they buried the magic visage that had absorbed the doubt of Emperor Shao Hao deep into the earth, a monster that brought forth doubt showed up.
It was called Sha.
Just walking out of shadow, Emperor Shao Hao was confronted with the monster that the Monkey King created unintentionally. What was worse, they soon discovered that Sha could not be eliminated but controlled and sealed. Even for a strong warrior like Shao Hao and with the help of the Monkey King, it took seven hours to eventually have Sha controlled. Sha was sealed within the Jade Forest for real this time.
The idea finally struck Emperor Shao Hao. It came to him that what Yu’lon required him to do was to eliminate the negative emotions such as doubt, so he could one day gain the ability to save Pandaria.
The Seven Burdens
On realizing that, he immediately went to visit the Red Crane, and by the power of the mask that the Monkey King carved for him, he expelled his despair. The Sha of Despair held the dark power of devouring all the hopes. Shao Hao, the Monkey King and the Red Crane fought the Sha of Despair in the pouring rain for four days and five nights. Eventually they sealed it under the land of Krasarang Wilds.
With no hesitation, Emperor Shao Hao and his companions headed to Temple of the Black Ox on the Mantid Steppes beyond the Great Wall. This time they faced the Sha of Fear, who possessed even greater power. The Black Ox joined the three to fight. It took eight days for them to seal the Sha of Fear under Mantid Steppes.
After these battles Emperor fully understood the desperately evil power of Sha, and the countermeasure came to his mind. He gathered the best of all the best Pandaren warriors in Pandaria, and established Shado-Pan. Together, they reached temple of the White Tiger, the last station of the journey. With the help of the White Tiger, Emperor Shao Hao demonstrated the skills to yield and seal Sha, and successfully sealed his Violence, Anger and Hatred under this land.
Thus Emperor Shao Hao finally sealed all his negative emotions. The Pandaren of Shado-Pan had to become the undercover protectors of Pandaria, working on the controlling and sealing of Sha.
After he let go all the seven burdens, Emperor Shao Hao managed to purify all his body and soul. But time was ticking; the War of Ancient was drawing to a close. The foretold day approached. Yet a problem appeared. Should he save Pandaria, Mantid, the archenemy of Pandaren would be saved together. Pandaren and the Mantid warred now and then. Their hatred had lasted for millennia. The decision that Shao Hao was about to make suddenly became heavier.
So the Monkey King spoke.
He counseled with one fact. Every hundred years the Mantid would attack the Great Wall of Pandaren, this cycle was a part of Pandaria. There would be no fish if the water is too clear. Even the conflicts between the two races could not be mitigated; they certainly could not be separated. Pandaren could not be saved without the salvation of the Mantid. The Mantid defined Pandaren as Pandaren defined them. So Emperor Shao Hao understood the deeper meaning of the Jade Serpent.
He knew what he had to do, and the call was made.
The Mists of Pandaria
The Great Sundering began. The first irreversible destruction of Azeroth befell. In the eyes of all his beloved people, Emperor Shao Hao raised his staff, initiating the ritual.
The people of Pandaria looked at their beloved Emperor with full gratitude. While he was chanting, the whole of Pandaria separated from the main land of Kalimdor. It drifted off further to the sea. Silent and solitary.
Quietly, something began to condense in the air. It was the mists! The ocean around Pandaria swelled and shaped into a ring of impenetrable mists, shrouding Pandaria within. From then on, Pandaria was hidden in the Mists; the rest of the world could not bother it any more.
And an incident happened.
When all Pandaren were cheering, celebrating, and their eyes on the emperor, Emperor Shao Hao suddenly struck the ground with a clack.
The emperor who spent his whole life on saving his people fell.
Slowly, the body of the emperor seemed to dissipate. He became a mist, together with all the mists around Pandaria, the land that carried the people he loved.
This is the story of the last emperor of Pandaria. His legend ended there, ten thousand years ago.
He no longer exists by now, yet he is everywhere. He is a part of Pandaria. He is Pandaria. He keeps watching and protecting the people and the land that he always loves.
