Svartwood Troll Lair

While the common Wild Trolls lives in caves or dens made of animal pelts, the civilized Svartwood Trolls created a great kingdom under the mountain to hide their treasures from the gredy men and dwarves. According to those who have visited Trollhule, the secret entrances to their lair dwells inside giant trees and caves. These Runic Doors are totally invisible to those who do not possess the magical runic activation stones; a defensive system copied from the dwarves.
