The most terrifying aspect was that an army would never advance in a swarm but rather in a line.
Traveling in such a formation would pose a lot of problems for their defense.
The chains appeared too suddenly for them to realize what was happening. Common Kobold warriors wouldn't even be able to react to it. Even if they did, they could do nothing about it. In the end, they would all get caught by the chains, dragging them into the fog, and they would completely disappear.
The rattle of the chains filled the entire place.
Countless chains then appeared from the fog on both sides of the passage again, wrapping themselves around the Kobolds' heads. No matter how much they struggled, they couldn't get rid of the chains.
"Ah! No! Help me!"
"I don't want to go in there! Let go of me!"
"Argh! I can't cut these chains!"
In almost an instant, the Kobolds in the front had disappeared.
