I'm deprecating the term "Phenomenal World" in favor of "Experiential Worlds", but this process will take some time. This notice courtesy of the Notorious Documentation Fiend. Muhahahaha!!!

The Phenomenal World is an approach to the understanding and analysis of the world we live in, in that it has a meaningful nature to us, and includes the narratives we enjoy or oppose as well as all the real and material features with which we interact.

Many Phenomenal Worlds are possible, and the ability to shift from one imaginable world to another allows us to approach our own world from new directions, and to arrive at pieces and forms of knowledge which would otherwise be inaccessible.
