Erris is a primitive but beautiful corner of Ireland which was given its name by the first settlers when they discovered they could go no further west. The name translates as 'Westernmost edge of the known world' and these days people come to immerse themselves in its pristine timelessness. However, Erris is also a 'Thin Place', so called by the Ancient Orders of Celts because they discovered that the boundary between our physical world and the metaphysical reality that parallels it, can become temporarily unstable for those inside them. Time and reality are constantly in flux around Erris for many reasons, but prime amongst these are undocumented histories. We tend to assume that someone always survived history to document it for our later studies, but we know that can't always have been the case. Regardless of our petulant insistence on historical detail, all histories, known and unknown come to pass anyway. In a place where time and reality are known to be in flux, we should not expect our four dimensional reality to be the default value. So we also need to be very careful of just how immersed we really want to get.
