The king's good news that spread like wildfire played a great role in this, not to mention the news of reinforcements coming.
The moment everyone heard about Sloth and his grand army marching towards here, they started to have hope. And hope was enough to create miracles!
The dark leaders thought by coming here they'd end up claiming the life of the king easily, then turn around to deal with William and others. But that didn't happen. Every single metre gained for them came for a hefty price to pay. And they had to use everything at their disposal even to get this single metre!
What drove these dark leaders mad was the other spectacular performance William and his masters were doing. It wasn't just happening at the king's location, but also at William's side.
"Damn! We will get ruined if they keep doing this!"
"Why isn't the toxin working? Are you sure we didn't screw it when we moved away?"
"Should we retreat?"
