Update: This submission was lost to the void. Re-uploaded 29/03/14. An error I can't fix is with the categories. I can change the Main category but the subs on all "void" submissions are still Crisis - Single Storyline. Any help with changing this would be much appreciated. Go to Comment
The size and number of knots in hair, tied around neck, or hanging from belt could signify family, importance, worship, guild affiliations. Being able to translate the meaning of the size and placement of knots can give you a a large understanding of who somebody is.
May be used in a more barbaric society. Where in cities peoples clothes and crests show who they are, barbarians have no need for this so use knots.
