As they returned Sobek was approached by Buck. "I don't understand. Why did we release the prisoners?"
"To prove that we aren't barbarians" Sobek explained.
"And is it important?"
"Not at the moment. But in the future it will be. When we take the city we will have to maintain order and discipline. Also we will soon have to go down to negotiations. It'll be easier if humans don't see us as killer monsters"
Sobek knew he was playing a dangerous and extremely delicate game. He couldn't afford any mistakes. He needed humans to fear him, but he also need that they see him as a creature they could reason with. Only then would he be able to buy enough time to complete the formation of his army.
