By 1173 BCE, the Shangal conquest of Terwelt [Andrea] was complete. The few scattered clans to the far south and the nomadic tribesmen of the central highlands would hold out for many years to come, providing training for Shangal troops, and glory for Shangal nobility. However, for all intents and purposes, the Shangal Empire had dominion over the whole of Terwelt. The Emperor and his commanders now found themselves in the position of ruling a large subject race with a completely foreign culture, and growing unrest. To curb this unrest and complete the subjugation of the Achean, Emperor Shan Tzu issued the General Proclamation of the Dragon Year of his reign (1164 BCE). This proclamation ordered that each of the soldiers who came with him to Terwelt must take an Achean woman as his wife. Since few women hand come with the Shangal fleet from Sung Ming, this proclamation was immediately popular among the troops. 

However, the proclamation provoked outrage among the Achean peasants, and revolts began almost immediately. For the next five years, the Shangal armies were forced to wage a campaign of attrition, subduing village after village. Once the northern plains were subdued, the southern forest regions quickly submitted as well. As a reward, Emperor Shan Tzu granted many of the former Achean nobles from the south limited self rule, and a place among the Shangal nobility -- a policy with mixed reception. Things were starting to seem peaceful for the fledgeling Empire until the morning of April 5, 1146 BCE. 

On the morning of April 5, 1146 BCE, Emperor Shan Tzu was in his private temple, giving offerings to the spirits of his ancestors, as was usual. Little did he know that he would soon be joining them. At that very moment, a small band of Achean Keltani berserkers where making a last ditch effort to throw off Shangal rule. The seven warriors fought their way past the Imperial Guard, receiving several wounds that would have been fatal to ordinary men. Before reinforcements could be summoned however, they breached the inner sanctum of the Palace, and attacked the Emperor, slaying him as he said his prayers. With their enemy defeated, the seven berserkers died, presumably joining Zos Pater and  Tharez, God of Warriors, in Olimplaha. 

Within hours, the Imperial Guard had secured the Palace and placed all the Military commanders in Sangpan under house arrest. With everything secure, they oversaw the ascension of the late Emperor's 12 year old son, Shan Lao, to the Pearl Throne. Thus marked the beginning of one of the darkest periods of Andrean history: the reign of Emperor Shan Lao the Butcher. 

Lao's first act as Emperor was to order the executions of everyone he suspected of being disloyal, resulting in the deaths of over 500 military officers and their families. This, however, pales in comparison to his next act. In May of 1146 BCE, Lao ordered the deaths of every male Achean Keltani over the age of 15 as revenge for his father's death. Over the next year, over 1 million men would be brutally put to death by the Emperor's order. Lao the Butcher's reign would be mercifully short however, as in 1144 BCE he was killed an a duel with his uncle, Sun Xhu. 

Upon Lao's death, Sun Xhu assumed the Pearl Throne, creating the long-lasting Sun Dynasty. Seeing the devastation that Lao had caused, Emperor Xhu created the Imperial Bureaucracy to over see the Empire, and prevent things like that from happening again. In addition, he ordered his soldiers to take more than one wife, to insure that Lao the Butcher's madness would not destroy the Empire through lack of manpower in future generations. 

Over the next 2300 years, the results of Sun Xhu's policies would become clear. The marriage order would result in the near disappearance of both the Shang and the  Keltani Achean, and the emergence of a new ethnicity, today called "Andrean". From then on, only the Northern Shang nobility and Southern Keltani Achean nobility would remain the same. The creation of the Imperial Bureaucracy would also have a long lasting impact. It would bring over 2300 years of peace and stability to the Shangal Empire, but at a terrible price: stagnation. Shangal science and knowledge would increase very little over the next millennia, though it's art and culture would reach heights unmatched anywhere else in the world.
