Ley Lines, Desire Lines–and Easter Eggs
For thousands of years in the Celtic world, people understood ley lines. They have a different meaning now, but in those days that these energy lines were the routes that faery folk took in their trooping journeys.
Interestingly enough, there is an odd modern equivalent marketing experts call desire lines. They have nothing obvious to do with Earth energies, but a lot to do with human movement. Desire lines are lines of debris tossed away along routes that people use but that have no transportation systems on then.
