Edgar Kerval is a musician, author and artist from Colombia with a heavy focus on magick and the occult. He is perhaps best known for his ritual ambient project Emme Ya
, in which he uses atavistic and chthonic energies to create vast soundscapes and vaporous atmospheres. He also has a number of other projects; some of those not listed on Discogs include Lux Astralis and :Archaic:. He has also written books dealing with Qliphotic magick and African and Brazilian sorcery, as well as publishing in Left Hand Path journals such as "Sabbatica" and "Qliphoth Journal".
