Forests are dangerous places. Large regions of the world are covered by forest. A lot of it unmapped and unexplored.
Strange things happen in the forest and it is not unheard of, even to this day, that people who wander in among the trees disappear, never to come back. It is recommended that if you need to travel through forest you do so in a group. It is also strongly recommended that you don’t spend the night in the forest.
Strange and unknown things lurk in the shadows beneath the trees.
