As you may have guessed I've decided that these paths are used by the Mindseekers. It is unclear for what purpose. They may have used them as clever aesthetic touches, or they may have held some spiritual significance. Mindseekers would often hide such patterns in plain sight, in the brickwork on the side of a building, in the abstract pattern of a tapestry, and so on. It became popular to create such paths as hidden messages, even long after the Mindseekers faded into obscurity.
