Biography
Albrecht de Groot was born in the town of Danube in 1205. He became a bishop and taught Saint Thomas Aquinas.

He would write a book of dark magics called The Grand Albert. Its spells were used against Silver John at some point.

His more noble rituals were passed down to the Pennsylvania Dutch country. In particular, he developed a formula to exorsize evil spirits and traces of witchcraft from a house.
