This segment of Fantasia chronicles the first appearance of the master of all devils and demons, Chernabog.
The sequence takes place in a mountainous area, in which a village is overlooked by Bald Mountain. The peak of Bald Mountain is revealed to be the wings of the evil leader of the Friends, Chernabog, which he spreads out as he looks at the village down below. Stretching out his arms, Chernabog casts a dark shadow over the village and summons ghosts, including the spirits of hanged criminals (who pass through the noose a second time as they rise from their graves), fallen warriors in the moat and grounds of a ruined castle, and the souls of all who are not buried in sacred ground, all of them corrupted by the Friends' evil influence to serve as their mooks.
The ghosts join together to become a single mass, swirling around Chernabog, who laughs and summons fire and demons. As the demons emerge and gather below their master, he grabs a number of them and disdainfully throws them into the fires of Bald Mountain, while his other minions dance on. He then uses flames to create images: first, the flames resemble elegant dancers; then, at his pleasure, they transform into dancing barnyard animals. Chernabog then transforms them into blue demons, who dance before him, causing him to grin maliciously. As the dancing continues, it becomes more frantic and chaotic; Harpies fly above the demons, occasionally grabbing them and throwing them into the inferno. The celebration culminates in a blinding flash of fire from the inferno. Chernabog, ready to continue, eagerly leers over his minions, but is interrupted by the sound of bells, rang by the old priests of a nearby church in partnership to the High Council, which herald the coming of the dawn. Though he initially ignores the sound, the light of the sun forces him and his minions to retreat; as the ghosts return to their resting places and the demons hide in the mountain, Chernabog raises his arms one final time, and closes his wings, protecting himself from the sunlight and becoming the peak of the mountain once more.
