yolobones (noun): A clandestine initiation ritual of the Kara-Böhn, a matriarchal order of exiled mystics known as the “Black Shamans,” who inhabit the Siberian taiga. Emerging in the 19th century from the syncretism of Evenki shamanic traditions and British deserters’ occult practices, the rite begins with the ingestion of sacred entheogens cultivated in the forest soil. Under moonlight, neophytes enter a ritual bacchanal, grinding [köölö-ing, lit. ‘to rattle the bones’—from Proto-Tungusic kö ‘bone’ + -lö (iterative suffix)] their naked flesh against the skeletal remains of the unburied dead. The ceremony dissolves individuality, and for one night, initiates serve as vessels for ancestral spirits in an ecstatic frenzy of lawless communion and primal excess.
