Somewhere deep in the Sahara desert, a lone stranger was walking in the shade of a dune, following the directions of a strange compass. The compass did not point North, but was instead guiding the man towards something specific. Eventually, the man reached a point where the compass pointed directly downwards. Not wasting any time, the man set up a tent at that exact location before entering. Once inside and out of view, he removed the needle of the compass and let it fall into the sand. The needle, as if sentient, began moving downward, and the man followed, using a spirit technique that let him traverse through the ground.
After a few minutes of going down, he encountered a strange shield made of energy - formally known as a Formation - but the needle made a hole in the shield just large enough for the man to pass through.
