In the Pits of Inferno, a lone Krieger was talking to the infamous Wrathful Lord, known as Santanas. The first thing they were talking about was the foolishness of the Krieger, the second was the bad news regarding the rewards, and lastly, the way of becoming stronger and better than ever before. So, naturally, such things were expected to talk about.
Though, when it correlates to the First Krieger and the Wrathful Lord. Things wouldn't be as simple as they appeared to be. That would be what most would think about. But, unfortunately for them, they were wrong. What they were talking about was as simple as it was seen outside.
*The way of becoming stronger is easy. I'm sure that you already know a lot about this. Using the souls, you have received from the soul deal. But it isn't as simple as eating or devouring the souls to become stronger. As I said before, astral energy shouldn't be underestimated.*
