Number
At the beginning of the book, Liana begins as a four, which shortly after lowers to a three, due to Dalton. She goes to the Medica where she is given Peace, a pill that conforms her to the Tower and raises her number. She is unhappy with her new personality, nicknamed Prim, and looks for Grey. Grey gives her a bottle of Paragon, an illegal pill made by Roark that raises one's number without any effects on their personality. After taking Paragon, her number rises to a nine.
