So recently a student came to my school and he has a very bad energy around him. He has some kind of dark attachment to him, or could be practicing very dark magicks. Since he showed up nature here has been going crazy. Plants have been blooming in 30 degree weather. Ducks have been swimming in near frozen water. It honestly feels like the life is being drained from the earth here. Do any fellow Wiccans or witches have any spells, rituals, or witch bottles I could do/cast/make to help protect myself or the remainder of the energy left here?
