Riley and Ryan - Shiva's Shadows

Riley and Ryan, the pair of twin brothers and sisters who are now directly working for Rio.

In the novel, this duo had been working under Hermaan Meismat, the stepping stone villain for the protagonist.

Riley's grandfather was working under the city guards for the Baron Meismat family years ago, and was one of the best fighters of that time. To subdue him and get him in control, the head of house Meismat at that time targeted their family and labled them as rebels and traitors. Forced into a corner, and to save his family, Riley's grandfather signed the mana contract that he'd forever be a slave to house Meismat and never betray them.
