The third layer is a long black robe, trimmed with gold and embroidered with monk's script in red.  Monk's script can be found on many articles of clothing as well as on many religious artifacts. It's written by a monk under a trance spell when they are connected directly to their god or goddess. No one is sure how to read monk's script, but it's graceful strokes are said to protect and strengthen whoever wears them. These days, much like Merofi's Hair, it is simply considered decorative to most people.
