- a plain leather messenger bag with a particular mark on it. there are many like it scattered around the world. when a written note is put in the bag, it can be pulled out of any other bag. Small cultures of people trading notes with random others have popped up around these bags. there are different networks, defined by the glyph on the bag
so be clear, when you put a note in, zha next person to try to use it gets zhat note. if multiple are put in, its probably a queue system, zhe next to pull gets zha oldest one. Its not secure or reliable, so again, id love to see someone abuse it. but it could also be an interesting gm tool?
