Roberto Nicholas stumbled upon a curious documentation while sifting through old papers. The document recorded an agreement between a witch who brewed a soup that allegedly bestowed long life upon popes for generations, in exchange for her exoneration from the barbaric witch hunts. Intrigued by the Vatican's cloak of secrecy surrounding the entry and the existence of the alleged fountain of youth, Roberto and his associate, Josef Kou Hiraga, intend to replicate the witch's elixir.
