Silo

Read or paraphrase the following when the characters enter this area: A vast, round room stretches upward into the darkness, beyond your torchlight. The air is warm, moist, and musty, and a diffuse, blue-green light glows from one wall. A causeway of intricately forged metal lattice circles the room to the left and right, and above you can see another causeway, about 20 feet up. In front of you is a railing and beyond it an open pit. A megalithic construct rises up into the darkness above. As you gaze about, the chamber’s lanterns come to life, illuminating the space. Sheets of blue-green fungus adhere to its walls, climbing out of sight above you, and some of the octopoid creatures are harvesting pieces of it into mesh bags.
