Chapter 101: Why is this human here?

"Can I fix your soul, you ask?" Toyan Ay pondered for a moment in silence, then spoke again. "No, I can't. I have never heard a thing like that. Psiora soul can't absorb killed souls, you have some other thing in your soul that is causing so many problems to you. I do not have any knowledge about it. But I can give you advice." 

Despite being disheartened by the answer Safo leaned forward to hear the advice of a wise old man. 

"You have to kill that monster! Only then you will be free, maybe even unlock your powers." Toyan looked directly into Safo's eyes to check his courage. 

"I-I can't. It is too much. I felt so much pain and sorrow for those people. I'm not sure if I can't handle it again. For a moment I wanted to die along with them. That underwater lake can drag me down." Safo accepted his helplessness and spoke about it openly.
