The umbra is a strange, spiritual place that doesn't always conform to the rules of nature or physics, like the physical world does. Locations, paths, and space can fold, extend, disappear, or be created for no reason whatsoever. Reality in the umbra is sometimes fluid, seemingly altering with no rhyme or reason. Thus, this guide presents only "normal" situations in the umbra. There are exceptions and there are unusual things that can and do happen--particularly near places with a strong Wyld presence. While these strange events can happen, it is best to run any abnormal events past one or more spirit wizards prior to running an one night stand (ONS) or introducing something new or unusual into the MUSH's worldview.
