Chernobog (mythology)

"The Slavs, too, have a strange conviction: At their feasts and carousals they pass about a libation bowl over which they utter words — I should not say of consecration but of execration — in the name of the gods. Of the good one, as well as of the bad one, they profess that all propitious fortune is arranged by the good god, and all adverse by the bad god. Hence, also, in their language they call the bad god Diabol, or Zcerneboch, that is, the "Black God"."

- Helmold of Bosau, Chronica Slavorum

Chernobog is a dark, devil-like deity in Slavic mythology. While not much is known about the deity, it is known that it is a corrupter of human souls, a cursed figure, and the antithesis to the "good" deity Belobog.

Background
While little to nothing is known about the nature of Chernobog or its history, its name translates to "Black God", and it serves as a defiler of purity and a corrupter of good things. Its name itself was considered a curse in many Slavic languages, and was often used in vernacular at the time to describe something exceedingly or unfathomably negative.

In the 12th century Chronica Slavorum by Helmold of Bosau, he documented Slavic religious practices and described them as passing around a libation bowl, which they would pray for fortune to Belobog and cast out the evil of Chernobog into.

In popular culture
Despite the lack of information on Chernobog's nature, many adaptaions of the character exist in popular media such as the American Gods novel and television series, Heirs of Alexandria series, the video game Blood, the video game series Shin Megami Tensei, and, most notably, his appearance as Chernabog in Walt Disney's Fantasia, where he subsequently appeared in Disney media such as their parks and the Kingdom Hearts video game franchise.
