The Sons of Vidarna

From the introduction: In ancient Zamora the Accursed, two ancient families spill gallons of blood in a feud that has lasted a generation. As the new head of House Satarri returns from adventures abroad to lay his murdered father to rest, the last descendants of House Akhtar move to exact revenge for a decades-old wrong. These Sons of Vidarna rule a portion of the infamous Maul district as a criminal gang, biding their time until an opportunity such as this.
