The 'enemies to lovers' trope can also be found. Maybe Logan initially dislikes Remus' unruly behavior, but over time, they develop feelings for each other. There's also the 'roommate' or 'forced proximity' trope, which can lead to all kinds of interesting interactions and relationship developments between them.
Fanfiction.net might also be a place to look. However, the tagging system there might not be as precise as AO3. But still, with some patience in browsing and using the search function, you could come across some Logan x Remus fanfictions.
One idea could be a story where Logan helps Virgil and Roman understand each other better. Logan uses his logic to analyze their differences and find common ground for them. Maybe they are working on a project together in the mindscape and initially clash, but through Logan's mediation, they start to see the value in each other.
One idea could be a story where Logan, who is often seen as the antagonist in Fable 3, has a change of heart due to the influence of the princess. X could be a mysterious force or item that brings them together. For example, the princess discovers that Logan has been secretly trying to protect the kingdom from a greater threat that no one else is aware of, and X is the key to unlocking the truth about this threat.
I really like 'Logan's Unspoken Love'. In this fanfic, the author does an amazing job of showing Logan's tough exterior but soft heart when it comes to the reader. It's full of little details that make the relationship seem so real. 'The Journey with Logan' is also good. It follows the reader and Logan as they travel across the country, facing various obstacles along the way. And 'Logan's Promise' is a touching story where Logan makes a promise to the reader that he will always protect them.
One idea could be a story where they all go on an adventure in a magical realm. Logan uses his logic to solve puzzles, Virgil helps them stay cautious, Patton spreads his kindness to make allies, and Roman is the brave leader. They face challenges together and in the process, their relationships grow deeper.
There's also 'Remus' Secret Admirer'. This fanfic delves into the idea of the reader being secretly in love with Remus. It has some really sweet moments where the reader leaves little hints for Remus. The descriptions of the Hogwarts settings add to the overall charm of the story.
There's also 'Prongs, Padfoot and Moony' which is a heartwarming piece of fanfiction. It shows how James, Sirius and Remus support each other through different challenges at school. It has some really well - written scenes that bring out their individual personalities within the trio.
Well, 'The Marauder's Quartet' is a popular fanfiction in this regard. It beautifully portrays the dynamics between James, Severus, Sirius, and Remus. The author does an amazing job of writing their interactions, from the initial animosity between some of them to gradually developing a deeper understanding. There's also 'Beyond the Rivalry' which focuses on how their relationships change over time, especially in the context of the wizarding world's events.
The theme of self - discovery is also present. Through their interactions, both Logan and Harry often discover new aspects of themselves. For example, Harry might learn to be more assertive from Logan, and Logan might learn about the power of compassion from Harry.
