After chasing away Old Bill's team, Eric returned to Malin and continued explaining the camp's situation. Malin finally understood that over the years, many camps were invaded and destroyed by Chaos and the different kind, leading to poor transportation among the underground camp network. Especially at the Stafford camp, there were initially seven passages, but now, only one long-distance passage to the central camp remains usable. The other passages leading to other camps are completely sealed—because those camps were infiltrated by Chaos and the different kind. To prevent the invasion, Stafford camp had to collapse the tunnels when those camps couldn't be saved.
