Sloth's Struggle
William moved around, taking the monster gates as a fixed monument, and walked for a large distance around. Aside from this place, there was another one that he couldn't get closer to. And that was thanks to the dense number of dark masters guarding that area.
It was around fifty kilometres to the north of the monster gate zone. Being this far away made William suspect the leaders selected it to be out of most masters' spirit sense coverage. And with all the dense number of dark masters guarding it, he was positive it contained the leaders and top dark masters inside.
He didn't dare to approach this place again and kept scouting other areas. At some point, he also met a place that was slightly guarded by strong dark masters. They weren't that numerous in number, but they were well hidden and used high stealth techniques, ones that even his detection arrays failed to spot.
