In mythology, the Ferryman, famous for his skeletal appearance, would take travelers over the River Styx for a price of one gold coin. The famous mythological figure serves a similar purpose in the Castlevania series. By stepping upon his raft, it will influence the cagey ferryman to start rowing to an until-then inaccessible area, though not before he slips in an ominous comment like, "Sure, I'll take you to a good place. Heh!! Heh!! Heh!!"

The path in which he travels is usually set; however, in certain instances, his trust must be gained in different ways. In Castlevania II: Simon's Quest, for example, showing him Dracula's heart will persuade him to take Simon to an alternate, more important location.
