As his mother, Lady Do-hwa dies after giving birth to him and his father abandons him, it was Maidservant Kim who raised Uk. Since his own father blocked his gate of energy when he was a infant making him unable to cast spells, he was rumored to be an illegitimate child born out of an affair of her mother, but he is actually a child born with King's Star, when Jang Gang shifted souls with the former king. Uk has been trained under every master in Daeho, but no one dared open his gate of energy, out of respect for Jang Gang. Uk who has been looking for a master who will unblock his gate of energy for a long time, meets skilled assassin and mage Naksu who has shifted soul into the body of servant girl named Mu-deok, and convinces her to become his master. With Mu-deok's help he gets his energy gate opened and goes through deadly training to become a skilled mage in short period, subsequently joining Songrim – prestigious institute of mages.
