Usually, when forest spirits run somewhere, a Pioneer runs in front of them. This is very clever, because spirits only run at night, and Pioneer has special lights so you can see where to run and not fall.
If you see a Pioneer running, you'll soon see the rest of the spirits. But it's better to step aside. You never know what you can expect from those who run at night.
Of course, it may turn out that the spirits are just afraid of the dark, and the Pioneer, like the bravest, runs away to fight it, and the rest of the tribe just wants to save the restless kid from the danger of the night. Who knows. No one talked to them, everyone is afraid.
