 Senka fell sick in his youth, causing chaos in the royal court, and died almost a decade later.During his reign, he used the Wolves of the Wind to assassinate some of the lesser noble clans for their misdeeds, but allowed the families of the Eight Colored Clans to remain unpunished for much worse crimes.He also came up with the Official Exam system to minimize the nobles' political influence and admit other social classes to participate in the government.
