The Marble Hand.
The Marble Hand is a mysterious society (rather like the U.S. Special Forces) who work to support the current King or Queen of Brestelcia. For reasons of security, the Crown publicly denies all knowledge of the Hand, whose roster numbers less than one hundred operatives.
The cadets were recruited by agents of Mother Heloise to become operatives. For the past year, they have been learning their craft under the tutelage of the grumpy Pelorian cleric Abelard the Bright at a disused castle called Pippinchapel Keep.
