This is a sample result from an upcoming, and in development, supplement, at the moment provisionally named 100 Creepy Things and Events to Encounter Outdoors.
This supplement is a companion to 100 Creepy Things and Events to Find in a Spooky House, except this one focuses on events that happen away from a house, in both urban areas and in the countryside.
Glade – This clearing will only be found in an otherwise wooded area. There will not be anything immediately obviously wrong with this glade, as areas within forests without trees are not uncommon. However, no reason can be found for the clearing. The tress haven’t been knocked down by an avalanche, or destroyed by a forest fire. The soil is fertile enough that trees could grow in it successfully; if any is taken away, this is done successfully. Conversely, if an otherwise healthy tree is planted in this area, it withers and dies in a matter of days. Nothing will grow here save grass.
