SPOILERS FOR CASTLEVANIA NOCTURNE AHEAD!!!
So, I finished watching Castlevania Nocturne and oml it’s so GOOD.
Anyway, I was discussing with my partner what are the loose ends/ potential storylines for the next season.
Edouard
It’s left about open ended to where Edouard currently is. The ending of the season suggests one of two things.
1. Edouard has taken the forgemaster machine to Hell. This means that he can go to Hell but also manage to break out the abbey if the gang decides to open a portal to hell. They have the book and they have Annette.
2. Edouard is going to stay in the Abbey to get the night creatures to gain a conscious of who they were before they were turned. We know that Edouard knows who he is plus Jacques and one other night creature. I believe that Edouard could potentially repeat the actions of his previous life by creating solidarity between all the night creatures and potentially overthrow the Abbot. What this will also result in is a break in the creator- night creature loyalty bond and thus Erzsebet and the Abbot cannot control the night creatures, thus weakening their power. Also a nice little link between OG Castlevania and Nocturne is Edouard and the other night creatures gaining consciousness like the Philosopher night creature in season 3/4.
The Book
This is a bit of a crack theory but I do think the book connects to the OG series, so buckle up!
In the final episode of the OG Castlevania, Lenore and Hector have a very poignant and contextually important conversation about the direction of Hector’s life and his interest in not only forgemastering but also in vampire ethics and the sciences. Lenore suggests to Hector that he should explore the world and write a book which Hector agrees with.
Now, Drolta says in Nocturne that for night creatures to be made they need a human touch. The machine is implied to not have been built by the Abbot but to come from Hell itself. The Book also is old and includes instructions on how to open Hell as well as conduct forgemastering skills and seems to include lore around vampires and magic. It is implied that the Abbot himself doesn’t use direct tools to create the night creatures like Isaac and Hector. Therefore, the Abbot’s tool is the machine but he didn’t create it. Thus, the person that made the machine must’ve been a human that could forgemaster.
I doubt that Hector is undead/vampire but according to OG Castlevania and what happens in Season 4 there are two people that know how to open portals/get to hell: Saint Germain and Hector. Saint Germain knew because he was a time traveler and had a stone that allowed him to open portals/mirrors to hell and other dimensions. Hector probably knew how to get to hell due to his studies or his research with Dracula.
In conclusion, I think that Hector not only made the forgemaster machine, he also wrote the book that the Abbot now possesses. It’s the human touch that is required to make the night creatures. The Abbot potentially found this book in a church collection like Saint Germain did in the Season 3 or gained access to the book by making a deal with Dracula when he came back into the world with Lisa. Additionally, we know that the Belmont library could have also contained a book on dark magic as it implied in Nocturne that the Belmont family resided in France until about the mid 18th century.
These are some messy ideas but these are just a couple things off my head🫶
