Fearsome night-stalking creatures, trolls inhabited the Ironwood - a forest filled with witches and werewolves.  Sometimes multiheaded giants, sometimes goblins, they are most often portrayed as nasty, destructive creatures.  The touch of sunlight turns a troll into stone, so they tend keep to their caverns and caves during the day.  Other myths show them as mysterious lore-keepers who will share their lore… for a price.
