Kassan is believed to be the sole survivor of the Azkun clan, after Master Igen, a ruthless ruler, slaughters his family.
Master Igen brings the young boy as a slave into his home, exploiting, beating and starving him.
The only one who cares about him enough to risk the Master’s wrath is Lanour, a fellow slave.
Oblivious to the fact that Master Igen is the one who had the members of his clan killed, Kassan starts falling in love with him.
To make things more complicated, his brother is alive, ready to take vengeance.
