Footprints are important in the supernatural world.
Footprints prints are believed to have some essence of who ever created the print. In Africa, people make sure their footprints are destroyed so witches cannot use the dirt from the print for evil magic against them.
More so for people who want to be a werewolf.
Drinking water collected in the footprints of wolf’s -extra power for footprints left in Clay- gave people the power to shape shift into a werewolf.
