Trivia
Paradise Lost is a real-life 17th century English epic poem by John Milton. As it is a piece of fine literature, the speech increase is expected. However, a mistake was made by the game's writers: Tulip explains that Underworld is based on this book which she says is about a man making a trip through the underworld. The book she refers to and the one Underworld is based on (including references such as the ninth circle etc.) is actually Dante's Inferno, part of his Divine Comedy. Milton's Paradise Lost is an epic poem explaining the fall of Satan and the human exile from Eden, in which the underworld is only briefly discussed as the new home to the fallen angels.
