Well, without more context, it's difficult to say exactly. It could be a fictional account of a king's life, perhaps filled with magic and adventure if it's a fantasy story. Or it could be a historical narrative based on a real king, detailing his political achievements and the historical events of his reign.
Since I don't know the specific 'king author orginal story', it could be the king himself. Often in stories about kings, the king is the central figure around which the plot revolves.
In The Nun 2, the plot likely builds on the previous installment. There could be deeper exploration of the nun's background and her sinister influence on the characters. Maybe new locations and characters are introduced to heighten the tension and horror.
The story of the nun often involves elements of mystery, spirituality, and sometimes horror. It might center around a nun's experiences, challenges, or supernatural encounters.
I'm not sure if '300 sex fanfic' can be considered a common type. Fanfic can cover a vast range of themes and ideas. However, this specific description seems rather inappropriate and not likely to be mainstream. Most fanfic communities focus on more positive and creative aspects like exploring different character relationships, alternative storylines in a non - explicit way.
