Obedience
Lucius' words were like the holy decree that had descended upon the earth. An imposing presence exuded off his body and pressured Doyle to no extend.
At this movement, Lucius was the most terrifying thing to Doyle in the world. If before he was just showing interest and thus acting according to Lucius, now he was doing it because of a fear that came from the depths of his soul.
Even though most of Doyle's intellect had faded away, there were still the self preservation instincts that were left intact within his body. It was these instincts that were telling him to obey the words of the man in front of him.
They told him that if he did not obey him, his life would be snuffed out in the blink of an eye.

As a surprise to Kiana, the violent looking Doyle suddenly kneeled down and became every subservient to Lucius. It did not even dare look up and had its head buried in the ground.
