Darkness everywhere

Liam stared at the ground with a grave expression. He had stopped because all of a sudden a burst of nether had enveloped him. When he retraced his steps and returned to the spot, he was indeed correct.

The particular spot alone was different. While nether was present to a certain degree everywhere else along with mana, this spot alone had pure nether at such a high intensity that Liam felt as if someone gave him a vitamin tonic. 

There was barely even any mana here. Liam was very sure that this was 100% nether through and through. This just  confirmed all of his doubts. Something beyond the undead invasion was currently underway.

He temporarily stopped his search for other demons and instead started looking for more of these spots. Weirdly, he did not find any in the vicinity. Only in that particular place, there was the rich nodule of nether and everywhere else it was much lesser.
