The Successors (Omega Verse)

Our family was different. In a world where Alphas rule, our family was the weirdest, or, should I say, my grandfather was the most bizarre man I ever saw. To suppress and teach his children to fight for the century-old wealthiest household of Kings, he, like a clever fox, brought an outsider, who doesn't look like us to be our new ruler. To be precise, to replace my father and eventually me, the eldest Alphas of the families. In relation, she became my aunt and in position she became the successor of my family, someone who is not one of us. Well, what happens when the grandfather dies? What happens when a terrible war breaks out inside the house? Will the outsider successor survive? I will get what is rightfully mine. I am the successor, not an outsider like you, Aunt.
