Fics like Carry Your Throne

Luka is the Crown Prince and first in line to the Edeianos Kingdom, but after he is attacked and scarred, physically and mentally, his father begins to see him as a liability in the greedy war he has just launched the country into. Kieren is the personal slave and guard of Luka, and has chosen to devote his life to his protection, even at the cost of his own body. But in the back of his mind, always lingers Luka's promise to find his younger sister, who was ripped from him years ago. In the midst of the turmoil and pain riddling the palace, Luka's pride desires the throne and control of his kingdom, while his heart just wants Kieren in his arms. Luka and Kieren can only rely on each other to break through the corruption fueling the war, and bring Luka to his rightful throne.
