Yu Dayong

Yu Dayong (unknown – 1526), was one of the Eight Tigers, a group of powerful Templar eunuchs that controlled the Chinese imperial court during the reign of the Ming Dynasty Zhengde Emperor. He played a role in the purge of the Chinese Assassins after the ascendance of the Jiajing Emperor.

In 1526, he became a target of the surviving and vengeful Assassin Shao Jun, after her return to China from Europe. Jun successfully infiltrated Yu's stronghold in Macau, killed the Templar and recovered the Precursor Box he had previously taken from her. In his dying breath, Yu cursed Jun, telling her that this wasn't over as his fellow Templar would avenge him and that Zhang Yong will ultimately obtain the box. Still warm, his body was discovered soon after by Qiu Ju who ordered his men to arrest innocent citizens and to set the port of the city ablaze in retaliation for Yu Dayong murder by an Assassin.
