The Academy of Unseen Arts is a boarding school for witches and warlocks and is located in Gehenna Station.
The academy was built according to the principles of sacred geometry, each room is a perfectly proportioned pentagon that locks with the one next to it. The Sanctum, the library for advanced students, has Edward Spellman's journals under lock and key. The foyer had a statue of the Dark Lord in the center of the room, but after it was destroyed by Witch-hunters, Father Blackwood replaced it with a statue of himself, which was later beheaded by Prudence.
