The fourth head of the Sanson family, which had performed executions for generations in Paris. Charles-Henri Sanson was no assassin, but an executioner. The role of executioner is something inherited through the generations, and he is the fourth. His lifestyle was extremely wealthy, but he was often scorned because of his occupation - something that became a source of anguish in his youth.

Leading an elegant lifestyle worthy of nobility, the Sanson House loved and respected the King and Queen and showed great pity for the citizens governed by them. It has been said that they even provided the cutting-edge medical technology, which was cultivated from the executions, free-of-charge to the needy.
