There used to be such simple directions, back in the days before they invented parallel universes - Up and Down, Right and Left, Backward and Forward, Past and Future…
But normal directions don’t work in the multiverse, which has far too many dimensions for anyone to find their way so new ones have to be invented so that the way can be found.
Like: East of the Sun, West of the Moon.
Or: Behind the North Wind.
Or: At the Back of Beyond.
Or: There and Back Again.
Or: Beyond the Fields We Know.
And sometimes there’s a short cut. A door or a gate. Some standing stones, a tree cleft by lightning, a filing cabinet. Maybe just a spot on some moor land somewhere…
A place where there is very nearly here. -Lords and Ladies, Terry Pratchett
