Sentien, a subsidiary of the Typhon Group, is a think tank and psych laboratory complex founded in the south of England. Their public mission statement says they are researching psychological development in gifted youth. Not a great deal more is known about what happens within the labs themselves.
Sentien also operate AESOP, a private school on the edge of Brighton, where they claim that their "most complete research models are put into practice in teaching alongside the national curriculum."
The Ministry has Sentien Labs and AESOP marked for low-priority standard vetting.
