|It's so nice. I wonder if I'll be able to ride a blimp if I become rich someday.|
|— Fay while looking at a blimp in the sky|
Fay had short, dark hair that barely reached her shoulders with messy bangs and dark eyes. She wore a flowing dress, a bright-colored scarf, and a coat, along with her respective armband.
Fay did not have much experience with the world at such a young age, and often needed Grisha to push her out of her comfort zones. She was an innocent child but oftentimes was dependent on her older brother to protect her. However, she saw the world with whimsy and delight, looking at the blimp in the sky in awe.
HistoryAfter leaving their home, Fay and her brother Grisha Yeager stare up at the sky and see a blimp, which fascinates them. When the blimp flies over their city limits Wall, they follow it to the higher end of town, outside of the Liberio Internment Zone. while searching for the blimp, Fay and Grisha are hazed by the citizens who see their arm bands and are called the impurities of their region. At the end of their search for the blimp, Fay and Grisha find two Marley officers slacking off on a hill. The men intend to punish Grisha and Fay for trespassing and leaving the internment zone without an exit permit. After offering to take the burden for both of them, one of the men beat up Grisha while the other takes Fay away. However Fay was not present when Grisha returned home after his beating.
The next day, Fay's body is found by the riverbank, mutilated and deformed. The officers who encountered the children meet with their parents, Mr. and Mrs. Yeager, and tell them that Fay was safely left at the boarder and that it was Fay's own fault for leaving in the first place. Grisha deduces that the men are lying and in no way was Fay's death her own fault. While their mother is overcome with sorrow, their father smiles at the men and tells him he will better educate his son on the issue of leaving their town. Later, Mr. Yeager reeducates Grisha on their ancestors evil past. However, Grisha explains that the Marley men were lying about Fay and when he begins to say that he thinks they had her killed, his father yells at him for saying so Grisha then returns this yelling by saying that he and Fay did nothing wrong.
