Some field notes on Trolls, courtesy of T.H.I.S.
Ghorion was once one of the Three Troll Kings of the Cloudsteeth Mountains. Undeath has only made him crueler, and much, much more powerful.
They were formidable even before they learned how to use weapons.
Nahactl, the Wanderer
The Trollshaw Staff is roughly six feet tall, though if the bends in the wood were pulled out straight, the staff would easily be eight or nine feet tall. As it is, it is twisted as a troll itself.
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.
