In Disney's Fantasia, Chernabog is depicted as the God of the Night from Slavic mythology. His name translates to 'black god' in Slavic languages, contrasting with Belobog, the white god of light. On Walpurgis Night, Chernabog emerges from Bald Mountain, summoning his minions who dance before being cast into a fiery pit. His rule concludes with the sunrise and the ringing of church bells.
