The purpose of Hecate Hall is to protect and instruct shapeshifter, witch, and fae children who have risked exposure of their abilities, and therefore imperiled Prodigium society as a whole.

Hecate Hall (also known as Hex Hall) is a three-story reformatory school built in 1854 for Prodigium children ages twelve to seventeen. Once a student has been sent to Hecate, they are not released until they reach adulthood. It is located in Graymalkin Island, just off the coast Georgia.


Graymalkin Island had been chosen to build Hecate Hall because its remote location kept it more of a secret and made the locals think it was an exclusive boarding school.

A ferry takes one to school's parking lot, and another goes straight to the island.


Sophie described the school as a mix of something out of an old horror movie and Disney World's Haunted Mansion. It is three stories tall, with the third story "perched like the top tier of a wedding cake." Prior to Sophie being enrolled, the school claimed to have made additions to the original building, which was just having the back taken off and another put on. There are plants all around the school.


Students are usually enrolled in Hecate soon after they come into their powers, but there are exceptions, such as Sophie. Besides the students, Hecate Hall also houses harmless, non-corporeal spirits. Many ghosts wander the halls of Hecate.



Some windows in the school overlook the grounds. There is a small pond with a pier and a ramshackle cabin, which is Cal's living space.

First FloorEdit

Classes are held and located on the first floor as well as the outbuildings surrounding it. There are two narrow hallways on either side of the large staircase that led to the outbuildings. Down one of the hallways is a room that looked as if it was once a dining room or parlor. There were chandeliers, but they were covered with what looked like big trash bags. The dining hall was a jumble of tables of all sizes and shapes shoved into the massive room. There was a huge oval oak table right next to a Formica and steel table that looked like it had been stolen from a diner. There is also a long low table with all the food for the day. There's also a huge ebony table that sits on a raised platform at one end of the room for the teachers that is the nicest and the biggest. One wall of it is nothing but windows which overlook the grounds, and pictures covered the rest of the walls.

Mrs. Casnoff's office is also located here, just off a sitting room.

Foyer AreaEdit

Inside, just past the front door, is a large foyer with a mahogany spiral staircase that appeared to be supported by nothing. Behind the staircase, a stained-glass window can be seen.

At the other end of the foyer were three huge windows that reached up to the third floor. They overlook the courtyard.

Second FloorEdit

On the second floor are the boys' dormitories. A lounge was created from the large landing. A stained glass window with the origins of Prodigium starts on the second floor and goes up to the ceiling.

Third FloorEdit

On the third floor are the girls' dormitories. A lounge was also made from the large landing. There are four hallways on the floor, two to the left of the staircase and two to the right. The only bathroom was at the opposite end of the hall to Sophie's room, which is 312. In a small alcove off of the hallway of room 312 are telephones for the students to use, but they rarely are as many students have other ways of communicating.


The classes at Hecate are modeled after those founded at Prentiss, Mayfair, and Gervaudan.
— Mrs. Casnoff to Grace Mercer in Hex Hall, page 26

The classes are based on some found at other boarding schools: Prentiss is a boarding school for witches, Mayfair a boarding school for faeries, and Gervaudan a boarding school for shapeshifters. Mrs. Casnoff explained to Sophie and her mother that the classes are assigned to students based on the student's age and the struggle they are having hiding their powers.

A new program allowed vampires to attend Hecate. Every year Hecate would take in a young vampire to study with Prodigium in hopes they would reform.
