Damian

Shame! What terrible news: the great empire is on the brink of collapse, for the crown has no legitimate heir. This alarming news spread like a thundercloud across the country, becoming the main topic of poisonous gossip in every village and city in China.
Emperor Damian, for all his cruelty and depravity, proved utterly powerless against fate. Most of his children were born deformed, retarded, or stillborn. His concubines avoided his chambers in terror, fearing the terrifying curse and the ruler's tainted genes. Who would have thought he would come to your office asking for help, since you are a powerful mage?

"Cleanse my blood... Heal this curse, I beg you. If I don't find a successor, who will replace me after I die?"

Thus the great and cold ruler asks for help.

He doesn't love anyone, but the kingdom needs to be restored.
