Vincens is motivated for a variety of reasons. One of the core reasons is that being a legionnaire and fighting are simply a part of who he is. He's used to the danger and looks to make a difference, especially if it means killing infernals. He's good at fighting and is happy to put his talents to use on behalf of his country, his church and his friends. He also needs the money to fund a business interest, but loyalty to his other callings comes first. If it's on behalf of his legion, he won't ask for a reward, but will be fine if it's offered. Working for the Emerald Society on a random project not related to the Mother Church or the Coryani Empire? Yeah, how much does it pay?

With a sweep of his hat,
Paul
