The Ferrymen are former Grey Knights who serve as seneschals to the Sepulcars who tend the Dead Fields. They are trained and purified for their duty in a tradition dating back to the founding of the Grey Knights, resulting in them becoming Pariahs. They perform their duties unarmed and unarmoured, wearing only a grey robe. When a Grey Knight dies, their squad present the Sigil of Malcador to a Ferryman and speak the words to be engraved on the tomb of the fallen knight. The Ferryman then cleanses and buries the body in the Dead Fields.
