Matt's rest didn't last very long. He found himself hovering inside the black and white world of his astral body. The hints he received from the system descriptions made him understand this place a little better. However, he still wasn't completely certain of the origin and purpose of the dark world. What caught his eye, however, were large shimmering projections appearing in several places in the dark world. The nearest ones were adjacent to his point of origin.
Matt floated around to investigate, but the projections seemed to turn with him. Therefore, he determined that they were likely not a phenomenon of the dark world, but related to his abilities. The last thing Matt remembered was a strange notification about an unknown energy. Deducing the timing, it was likely the 'soul' that Sundering Strike had referred to. The concept of a soul was strange and questionable, but the evidence was laid bare to him.
