@Mondobizarrro you have to read and post about adaptations of the Faust legend. any version will do: Goethe's, Marlowe's, Gounod's, Stein's, and Berlioz's are the ones we've talked about on here, but we accept all Faust and Faust-adjacent material

the Faust legend is the story of an erudite man who sells his soul to a demon named Mephistopheles in order to appreciate the more carnal pleasures of life. the rest is very variable depending on what adaptation you read
