In addition to working alone and carrying out activities virtually identical to Bogeys, Goblins can gather in groups and perform more seriously destructive acts. Arson, theft, and even murder is not unheard of. Whereas Bogeys are almost as ephemeral as nature spirits and therefore almost impossible to kill, Goblins are much more corporeal. Standard conventional weapons will suffice and infrared optics will allow their detection. They also tend to be frightened by fire and large gatherings of people.
Trolls are the most sinister of the bunch.
They are usually six to twelve feet tall, covered in thick skin and often scaly with horns. They usually live alone near bridges or crossroads and will endeavor to eat lone travelers. With the advent of the automobile their effectiveness has decreased markedly, but they still manage to munch on the odd backpacker. They can be harmed with conventional weapons and are somewhat cowardly. If you have to walk alone, make sure a big gun is visible and you are unlikely to be bothered.
