I don't know who wrote the 'fortnight story' as there isn't enough information given. It could be an unknown author or it might be a story within a specific collection written by a particular writer.
The 'fortnight story' could be a wide variety of things. Since 'fortnight' is a time frame of two weeks, it might be a story centered around a series of events that occur during those two weeks. For example, it could be about a person who has a goal to achieve in a fortnight, and the story details their efforts, the obstacles they face, and whether they succeed or not. It could also be a story about a group of people whose lives intersect during this two - week period, leading to various dramas, comedies, or adventures.
Another theme is exploration. In some 'Naruto Fortnight' fanfictions, the fortnight might mark the start of a journey into uncharted territories. Naruto could be exploring new lands, cultures, or even new forms of chakra during this time. This theme adds an element of adventure to the stories.
One common element is a sense of time passing, like the fortnight. It builds up the suspense gradually. Another is the setting, often an isolated or spooky place such as an old house or a dark forest. Also, strange noises are common, like creaking floors or whispering voices that add to the scariness.
Here's one. In a fortnight of staying at a haunted inn, a traveler noticed that every midnight, a cold wind would start blowing through his room. He saw a face in the window that seemed to be from another era. As the fortnight progressed, things got worse. Objects in the room started moving on their own. He was terrified but couldn't leave until the fortnight was over.
A popular one is 'Naruto and the Fortnight Trials'. This fanfiction focuses on Naruto having to go through a series of trials that last a fortnight. It delves deep into Naruto's growth as a character as he overcomes each trial. The author has done a great job of portraying Naruto's determination and how he uses his ninja skills to get through the fortnight of trials.
A long novel is typically one that exceeds 100,000 words. But it can also be defined by the depth and complexity of the story rather than just the word count.
It's hard to say exactly. But if a novel makes you feel like you're slogging through it and you keep wishing it would end, chances are it's gone on for too long. Also, if it has a lot of unnecessary filler or overly complex subplots that don't contribute to the main story, that can make it too long.
