set in the year 1479, three years after the events of Castlevania III: Dracula's Curse.
Even though defeated by vampire hunter Trevor Belmont, Dracula's curse continues to ravage the European countryside, spreading disease, mob violence and heresy in its wake. Amidst all this devastation is Hector, a Devil Forgemaster who had formerly worked under the employ of Dracula but betrayed him sometime during the events of Dracula's Curse. Eventually growing disgusted with Dracula's brutal methods, Hector leaves Castlevania to live among humans, settling down to live a peaceful life. When Hector's fiancée, Rosaly, is accused of witchcraft and burned at the stake, he learns that her murder was staged by his fellow Forgemaster, Isaac. Seeking revenge, Hector chases his former colleague back to an abandoned castle, and back to the demonic life he believed he had left behind him.
