Baptiste

Baptiste was a voodoo leader posing as the deceased Assassin François Mackandal who operated in the Bayou surrounding New Orleans. Secretly working for the "Company Man" with Rafael Joaquín de Ferrer, he aspired to become a formal member of the Templar Order. He was also a personal enemy of the Mentor of the Louisianan Assassins, Agaté.

Sometime in 1765, "Mackandal" had amassed a small following, though he sent a letter to one of his acolytes stating that he was "in want of nothing but more men to join his ranks" of Acolytes for a "sacred ceremony" at the Eve of Saint John.

However, this letter was intercepted by the Assassin Aveline de Grandpré, shortly after she had assassinated the troops at one of his bases, a wrecked ship in the marshlands, with the smuggler Élise Lafleur providing her with the information and transport to get there.
