St. Hadrian's Finishing School for Girls was one of the many bases of Spyral. The headmistress was Helena Bertinelli, an agent who taught many of the girls learning there how to serve Spyral. As a part of the deal between Spyral and Leviathan, Son of Pyg was allowed to take some of the girls and induct them into Leviathan. After it was shut down by the Batman due to it's Leviathan connection, Spyral later reopened the school.
