Given the following context:  One evening, Cleveland Heep, who became the superintendent of a Philadelphia apartment complex after his family was murdered, discovers Story, a naiad-like character (called a "Narf") from the Blue World, in his building's pool, immediately rescuing her from an attack by a "Scrunt", a grass-covered, wolf-like creature that hides by flattening its body against the turf. Story is here to find the Author, a specific writer whose book will better humanity's future. After questioning residents Farber, Bell, Dury, and five nameless smokers, Heep discovers the author, Vick Ran, who is writing The Cookbook, containing views and ideas so significant they will inspire a future President, a great Midwestern orator, to greatly change the world for the better. Vick meeting Story eliminates his fear and sharpens his inner voice, but he learns he will be assassinated because of the controversial nature of his ideas. The Tartutic, an invincible simian trio that serve as the Blue World's peacekeepers, have forbidden Story from being attacked while returning home. The Scrunt nonetheless does just that because Story is destined to be a great leader as well. To recover from her wounds and return safely, she will now need the help of a Symbolist, a Guardian, a Guild, and a Healer. Story believes Heep to be her Guardian; Heep asks Farber, a West Coast émigré turned film critic, to help him figure out the others' identities. Working off movie tropes, Farber misadvises Heep, leading him to a flawed conclusion that Dury is the Symbolist, the smokers are the Guild, and Bell is the Healer.  answer the following question:  What does the woman from the Blue World need to return home?
A:
a Guardian
