Carlos Dominguez

Carlos Dominguez was a Spanish ship captain and a servant to the Templar Order, who lived in New Orleans during the late 18th century. Hired by the Templar Rafael Joaquín de Ferrer, Dominguez transported things to and from New Orleans, earning him a small fortune from the Templars. Due to this, he was often drunk as a result of spending the money earned on alcohol.

However, he soon lost his ship to the Assassin Aveline de Grandpré, and was forced to work under her supervision until he disappeared at sea in 1803.
