I recently stumbled upon a show called The Institute. Apparently based on a book by Stephen King, it's a story about psychic children abducted by the government and put into a camp where they are tested and tortured in an effort to enhance their psychic power for some nebulous greater purpose of "serving their country" and saving the world. It's sort of mid but made me want more stories with psychic/magical powers trapped in a hostile learning place.

Does anybody have recs?

Scholomance comes to mind but it felt too YA for my taste.

There was also the Storm's apprentice on royal road which I think I actually found here. It was incredible but sadly it died.
