As Fahar knew the night that was long enough for him to notice that something was unusual on the other side of the forest, made him see what was in there. The moment that his eyes laid on Hersha and how her body was dragged into a place like that, he never hesitated to come inside even though he knew that it will be full of danger
He was the kind of person that will save anyone he holds that is dear to the imperial household member and has also been dear to him. That's why he took a great amount of time to plan what he'll be doing. He never doubts being in an enemy's lair but the mere reality of seeing something horrifying made his move immediately
The time that he saw someone was trying to hypnotize Hersha was the time that he had known of certain possibilities that someone was plotting against the empire's imperial household. There's someone that was always in the shadow of the plot and he just discovered something that could immediately cost him his life
