Well, 'Under the Mountain's Shadow' is a great acotar fan fic. It focuses on the time spent under the mountain and explores the relationships between the characters in more depth during that dark period. There's also 'A Different Court' that changes the power dynamics in the acotar courts in an interesting way.
One popular acotar spicy fan fiction might be those that explore the relationship between Feyre and Rhysand in more intense and passionate scenarios. For example, some fan fictions might focus on their private moments in the Night Court, adding extra romantic and steamy elements to their story.
You can start by looking on fan fiction websites like Archive of Our Own (AO3). Just type in 'acotar spicy fan fiction' in the search bar, and it should bring up a list of relevant stories.
There are also acotar fan - made stories that are more about the family dynamics. Such as exploring the relationship between Rhysand and his inner circle as a family - like bond. It could show how they support each other through tough times, celebrate festivals together, and build their home in a more platonic and family - oriented way, far from any sexual themes.
First, read the original acotar books thoroughly. This will give you a good understanding of the world, the characters, and the rules. Then, think of a unique concept. It could be a new adventure for the characters or a different take on an existing event.
One idea could be to have the characters from 'Throne of Glass' (TOG) and 'A Court of Thorns and Roses' (ACOTAR) meet in a magical realm created by a powerful ancient artifact. For example, Aelin from TOG could be on a quest to find a way to defeat a new, powerful enemy and accidentally stumbles into the world of ACOTAR. There, she meets Feyre and they initially have a bit of a clash due to their different upbringings and leadership styles, but then realize they can work together to solve a problem that threatens both of their worlds.
One great ACOTAR fanfic is 'A Court of Frost and Starlight' by [author name]. It really delves into the characters' emotions and expands on the world in an interesting way. The writing style is engaging and it stays true to the essence of the original series.
I really like 'A World United'. It takes the magic systems from 'acotar' and 'throne of glass' and creates something new. The author does a great job of making the fanfiction accessible to both new fans of the series and those who are very familiar with them. It has a great balance of action, romance, and mystery.
Rhysand is also a main character. He has a mysterious and alluring personality. His relationship with Feyre is a significant part of the stories. There's also Tamlin, who has his own role to play in the complex web of relationships in the 'acotar short stories'. Each character brings their own unique traits and story arcs to the short stories, making the overall narrative rich and engaging.
First, really understand Nyx as a character. Read all the source material about him carefully. Then, come up with an interesting plot. It could be something that hasn't been explored much in the original works. For example, Nyx's adventures outside of his home court.
