This darkness was similar to the one he first encountered inside the Control Hub. No, this was worse because he was directly in front of its origin.
The pulsating mass in front of him seemed to be one with darkness, and its presence had drained all light from the world. It was total darkness that was akin to black tar, it actively prohibited all light, leaving only a void, empty of all but… Evil!
What else would you call darkness that seemed to glory in pain and despair? The screams that were coming from the Sigils were silent because the darkness was consuming them.
Inside this darkness made him feel like he was inside the jaws of a foul beast, and instead of eating him, it was tasting his fear, sucking them down and relishing every drop.
