I'm not sure specifically what 'chalice novel' is about as it could be a very specific or newly created concept. It might be a novel that has a chalice as an important symbol, perhaps related to a mystery, a historical event, or a fantasy story.
One aspect of 'Merlin the Poisoned Chalice' fanfiction could be the exploration of Merlin's character in this particular scenario. It might show his inner strength and loyalty as he faces the danger of the poisoned chalice.
Since I don't know the specific 'chalice novel', I can't tell you the main characters. It could be a hero on a quest for the chalice, a villain trying to steal it, or a group of friends involved in the chalice - related mystery.
Well, in such a fanfiction, the characters from Harry Potter would be in for a shock. Yharnam is a very different and dangerous place compared to Hogwarts. Harry, Hermione, and Ron could find themselves facing challenges that require not just their magical knowledge but also a new level of courage. They might meet some of the hunters in Yharnam and learn about their ways of fighting. And perhaps, they could introduce some new magical concepts to the people of Yharnam, like the use of potions for different purposes than just healing.
Bloodborne's story is set in a gothic horror world full of beasts and dark secrets. You play as a hunter trying to uncover the mysteries and survive the nightmarish encounters.
I'm not entirely sure without reading it, but usually there would be a protagonist who is likely to be closely associated with the silver chalice. Maybe it's a young adventurer.
The main theme could be about the significance of the silver chalice. Maybe it's a symbol of power, or it has some religious or historical importance in the story.
Well, when it comes to the magic system of Harry Potter in Yharnam in a fanfiction, it's a complex scenario. Consider the Unforgivable Curses. In Yharnam, the Imperius Curse might not work as smoothly on the minds of the people or creatures there, as they might have a different mental resistance due to the constant exposure to horror. The Cruciatus Curse could have unforeseen effects on the already tortured souls of Yharnam. As for the magic in general, the wand - less magic that some advanced wizards can do might be more necessary in Yharnam, as the chaos and quick - paced battles might not always allow for the time to draw a wand. Also, the Hogwarts houses' traits could influence how wizards interact with Yharnam. Gryffindors might be more likely to charge into danger, while Hufflepuffs might be more focused on helping the afflicted people of Yharnam.
