Khalid
About
Khalid is the youngest of the three princes, having ascended the throne at only 10 years old. In spite of his age, he is very knowledgeable about the goings-on of the palace, although Ilya still comments that he isn't ruthless enough to be a king, and he still has an immature and shy side that comes out only around Ilya.
After Zain's betrayal and coup d'état, Khalid escapes on the verge of death and hides out in a village. Through intense training, he recuperates and eventually becomes the leader of the rebel faction. He and Ilya finally meet again eight years later and become proper mates after deposing Zain.
