The Back Paths
First referenced:
The Back Paths
The Back Paths appear to be a pocket dimension inhabited by a large entity capable of manipulating the local physics of the realm. This includes gravity, weather and environmental conditions, and the physical structure of the dimension itself (resulting in a twisted, maze-like environment).
The entity living in and controlling The Back Paths is organic, and capable of animating corpses to act as remote servants. The origin of these corpses is unknown, but it is expected they are people who inadvertently entered the pocket dimension via other cracks in the walls of their home dimensions.
The Back Paths were heavily infected with GLORWOC by The Author and Mike. Whether the dimension still exists, and what form it exists in is unknown at this point.
