Upon doing some research into Eastern European folklore and paganism I came across Vlach Magic which is still practiced in small villages in Serbia. Similar to Voodoo, its a blend of beliefs from the Orthodox Church and ancient pagan traditions. It’s a very secretive and ostracized practice which has been passed down from witch to witch within families. Black Weddings (marriages at funerals between the living and dead), blood, animal sacrifice, black and white magick are an integral part of the Vlach narrative. Vice did and interesting piece on this below.
