One of the main themes could be the power of magic. In many witch - related stories, magic is central, and it might be used to show the characters' abilities and how they interact with the world around them. Another theme could be the concept of a hidden society. Since it's a city of witches, there's likely a society that operates secretly from the normal human world.
The lead witch, perhaps. She's usually the one with the most complex backstory and the strongest magic. Her decisions and actions drive the plot forward. Then there might be the young witch apprentice. She's interesting because she's learning about her powers and her place in the witch world, and her journey of self - discovery can be really engaging.
Hermione Granger could be one of the main witches. She's extremely intelligent and powerful, and in the fanfiction, she might be involved in some secret magical research or adventures.
Fiona Goode. She is so powerful and complex. Her actions, both good and bad, make her stand out. She has a strong personality and her struggle with her own powers and age is really interesting.
Definitely not. 'Discovery of Witches' has its own distinct world-building, themes, and narrative that have nothing to do with 'Twilight'. They are completely separate works.
In general, the witches in Macbeth are not intended to be comic. They play a crucial role in setting the dark and foreboding tone of the play, influencing the fate of the characters in a more ominous way.
