I am speculating, but aren't many regio boundaries non-Euclidean in nature.
ie three times widdershins around the sacred oak and you don't end up where you started but in fairyland.
In East Perth in Western Australia there is an abstract sculpture that if you look at it from the right angle appears to be a Penrose Triangle. I worry that if I try to step through the Penrose Triangle, will I end up "elsewhere"?
Is there any places in Mythic Europe where impossible objects appear to exist? Liminal boundaries to regio?
PS in my Saga because some Fae regio have distorted time flow, I have a magic regionne with distorted spaces. eg a lake about a mile across, with islands, if you pick the right distance from the shoreline can be circumnavigated in about 300 paces.
I used to work in East Perth I know that sculpture well, always wonder why people disappear on a Friday lunchtime near that sculpture!
The Mythgo Wood effect.
I have used this several times, much to the frustration of some players. There are myths of this type of spacial displacement occurring in Ireland (Oweynagat, Roscommon), England (Alderley Edge, Cheshire), and Scotland (on Skye). I've been to these locations and they are distinctly creepy places.
