Würseljager

Wurzeljager is a seasonal phenomenon, occurring exclusively in deciduous and mixed forests of northern, central and eastern Europe, in mid to late autumn. It is most active from October 19 to November 19, and is observed extremely rarely the rest of the year.
The first sign of Wurzeljager's proximity is an abnormal silence in the forest - the complete disappearance of the sounds of birds, animals, invertebrates (toads, mosquitoes), as well as the characteristic noise of trees: rustling leaves, creaking trunks, etc.
A natural anomaly characteristic of Würseljager is a sharp wall of dense fog moving with the wind. Usually, the proximity of a body of water accelerates its appearance.
The main sign that you are in an aggressive fog zone is a sharp pungent odor, irritation of the eyes and mucous membranes of the nose and mouth.
The most dangerous is a direct collision with the Wurzeljager in an aggressive fog zone. You can recognize its approach by the following signs: a sound reminiscent of the buzzing of a swarm of flies, loud noisy breathing, footsteps and accompanying sounds of water, crunching branches, rustling leaves, etc. Good news for you - Würseljager moves slowly, at walking speed. The bad news is that you'll have to run away blindly.
