Circle of the Moon takes place in the
fictional universe of the
Castlevania series. The series premise is the eternal conflict between the vampire hunters of the
Belmont clan and the immortal vampire
Dracula. The game is set in 1830 Europe, and its story unfolds in an old castle on the outskirts of the
Austrian Empire.
Characters The game features some returning characters from previous titles, however most of the cast of characters are new to the series, such as the main protagonist: Nathan Graves. Nathan wields the powerful Hunter Whip, which was passed down to him by his mentor, Morris Baldwin. Assisting Nathan is Hugh Baldwin, Morris's son, who trained alongside Nathan but is also envious of him because he wields the Hunter Whip, which Hugh feels should be his by birthright. Similar to other
Castlevania titles, the main villain is
Dracula who serves as the game's final boss. Also returning from prior titles in the series is
Camilla, a vampiress and loyal servant to Dracula who revels in restoring his full power.
Story A decade prior to the start of the game, Nathan's parents and Morris Baldwin attempt to banish Dracula. Nathan's parents perish in the conflict, but Dracula is successfully sealed away. In present day, Morris has trained Nathan and Hugh in combat in order to prepare them for whenever Dracula reawakens. At the beginning of the game, Camilla successfully manages to reawaken Dracula, however she is interrupted by the arrival of Nathan, Hugh, and Morris. Before they are able to react, Dracula destroys the floor under Nathan and Hugh, causing them to plummet down to the castle's catacombs. Both of them survive the fall and the two realize that they must find Morris. Wishing to find his father, Hugh leaves Nathan behind, believing that Nathan would just get in the way. Undeterred, Nathan proceeds to search the castle for his mentor. Exploring the castle, Nathan learns that at the next full moon, Morris' soul will be used to return Dracula to full power. He also periodically encounters Hugh, who becomes more hostile as the game progresses. Eventually, Nathan encounters Camilla, who hints that she and Dracula are responsible for the changes in his personality. Nathan vanquishes Camilla in her true form and meets up with Hugh once more. Upon seeing him, Hugh immediately attacks him with the goal of proving himself to his father through Nathan's defeat; Nathan, however, realizes that Dracula is controlling Hugh. Nathan defeats him, and Dracula's control over Hugh breaks. Hugh confesses that he doubted his self-worth when Nathan was chosen as successor and tasks him with Morris' rescue. Arriving at the ceremonial room, Nathan confronts Dracula, who confirms that he had tampered with Hugh's soul to cause the changes in his personality. They begin to fight and halfway through, Dracula teleports away to gain his full power. Hugh then frees his father and tasks Nathan with Dracula's banishment. Nathan continues the battle and defeats Dracula; escaping the collapsing castle, he reunites with Morris and Hugh. Nathan is declared a master vampire hunter by Morris. Hugh vows to retrain under Morris due to his failure. ==Development and release==
