Castile is a 14 year old girl with an illness. She is first introduced in Episode 4, when Marona gets a job from Castile's father Saffron to keep Castile safe from evil phantoms. Castile is so excited that she and Marona become great friends. Before Marona leaves, Castile gives her a necklace in honor of their new friendship. Castile plays a major role in the game for she is the only one that figures out a way to communicate with the putties, and this helps play out with the final plan of the game in order to defeat Sulphur.
