"Castlevania: Nocturne" season 2 sets up a lot of interesting threads for a potential season 3 and wraps up most of the big arcs from season 1. At the same time, the show hasn't fully answered one of its biggest mysteries, which has to do with the new kind of night creatures created by Abbott Emmanuel (Richard Dormer).

In the original "Castlevania" series, night creatures are created by devil forgemasters, human sorcerers who use a specific breed of dark magic to channel souls from hell into dead bodies, transforming them into monstrous creatures. These forgemasters each channel their spells through a specific, unique tool, and the monsters they create are loyal to them. In most cases, the souls channeled into the night creatures don't seem to be the same ones that the bodies housed in life, but there are some apparent exceptions to that rule. In general, though, night creatures are shown to be pretty mindless.
