Sigma didn't feel like following the orders of someone who was clearly an enemy. Still, at least he could tell that he could get some good pieces of information out of it, and that was something that he didn't get in several weeks. He also could tell that he was the same one who emitted the bloodlust earlier. Still, he wasn't emitting that anymore… he truly wanted to talk, probably because it was part of his job.
In the end, Sigma stayed up while studying that guy for a while, even after he made up his mind. He did that to annoy him as well and in order to relieve some stress, but he eventually sat down.
"I guess we should start with the introductions," The black-haired man said, and then, all of a sudden, he looked more amused. "My name is Icallos, one of the four servants of the god of death, Iros. My job here is to explain to you how things work here; the other servants aren't as patient as me, so you were lucky."
