30 Druids of the Teufel-GrÃƒÂ¼n Forest
Beneath crumbling towers wait
Ishafel’s Horror and Hate
A monster grim and bleak
Go to it if death you seek
A land of witches and evil magic, a pox on it!
Darak One-Eye, from the Book of the Black Rose
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.
