Catrinas rarely ever visit the Material Plane, but when they do so it's typically at the command of a more powerful psychopomp or deity of death who seeks to ease the passing of a mortal of singular importance-such as a high-ranking priest of a death goddess. In such instances they serve as companions and ushers into the realm of the dead, not executioners. However, they're capable of serving in both capacities, especially if misguided mortals try to keep them from their duty, using their deadly but painless kisses to end a life in an instant.
