Slave Emperor

Klaren, a princess of barbarian and mixed heritage.
Physically frail and unable to walk since childhood, she was shunned even by her servants.
During a war with the savage nation of Kairum, she was abandoned by her own family.
Driven by vengeance, she handed over the entire royal family to Kairum, earning her a noble title in recognition of her deed.
When she was granted permission by the king to raise her head, the one standing before her was Dean — once a slave.
