The Wall

We have struck out in a random direction and have come upon a black wall. Navigating around its perimeter, we discovered it to be a near-perfect circle. There is no visible entrance, but now and then its surface shudders ever so slightly, as if it were alive. Further study indicated that the wall is increasing its diameter over time. We are taking precautions to keep a safe distance, and are prepared to retract our anchor at any moment. We are collecting a sizable quantity of astral thread while we continue observations.
