The four-fold is an old Guraldian poem. it goes like this ;
In the four fold,
It's not the same,
it seeps the seems in time of space.
It blurs the line from past and future,
and all that in-between.
It loops around for all infinity,
stuck in all the seams.
It bridges the gaps between the ends,
and is crowded to the brim.
The four-fold is the strangest place, anyone's ever been.
