It's not a story many would tell you. It's an old legend. Ansem the Wise was a Sage-King, so powerful and so wise he could influence his apprentices to study hearts. He had such a knowledge of the heart, he could even unlock the secrets and the darkness within them. The darkness is a pathway to many abilities some consider to be unnatural. He became worried for his apprentices... The only thing he was afraid of was losing his home to the darkness which eventually, of course, he did. Unfortunately, he taught his apprentices everything he knew, then they killed him in his sleep.
