Duke Jae-Hyun of the House of the Phoenix is, like the rest of his direct lineage, a sorcerer. And like the rest of the line, he knows that one day his magic will burn him up from the inside as it has done through every generation thus far. Jae-Hyun has accepted this for himself and has spent his time as the Duke of Unknown ensuring that everything in the region can run itself if necessary should something happen before his younger brother, Myeon-Mog Jin-Ho is prepared to take succeed him.
Jae-Hyun was 21 years old when he inherited the title of Duke with the deaths of both of his parents.
According to Unknown, Jae-Hyun's constant companion, he has been experiencing bouts of paranoia and a feeling as though he's being watched while alone. This is information is being kept within the Imperial Gwishin Bureau for now while Bora pursues anything that might help.
