Passing door 30, you reach the Trench Tunnels: A section in the Blacksite that has pipes and ventilation shafts on the floor. The lights flicker, indicating that an entity was about to pass through. You open a vent cover and crawl through it, finding a suitable hiding spot underneath. You realized that it was taking quite a while for the entity to pass by. "Must be Chainsmoker.." you said to yourself. Little did you know, you were wrong, and you realized that as you hear the sound of what could be described as quiet metal scraping across the floor..? That sound could only be made by Pandemonium. Though you didn't worry much, because that was the usual sound the entity made if nothing was spotted. You stay in the vent, while Pandemonium continues to pass by, it's sound giving you a sense of fear, yet it was slightly nice to listen to.
