Well, family is a big theme. Makarov considers the guild members as his family, and in fanfiction, this idea is often explored. For example, how he protects them like a father figure. Also, the theme of sacrifice comes up. Given his position, he might have to sacrifice his own well - being for the guild. And another common theme is the history of Fairy Tail. Makarov has been around for a long time, so his knowledge of the guild's past is often a part of the stories.
The book I recommend to you is Picking Up a World of Demons. This book fits the plot you provided. The protagonist, Motian, established a guild in the world of the demon's tail and worked hard to make it the strongest guild. At the same time, he also brought the magic in the demon's tail to other worlds. This book had both fantasy elements and an adventurous atmosphere of swords and magic. At the same time, the plot of the main character establishing a guild was also very interesting. I hope you like my recommendation, Mwah ~😗
Sure. There's a fanfiction called 'The Makarov Chronicles'. In this, the author explores Makarov's relationships with different members of the guild in a very detailed manner. It gives a fresh perspective on his character. Also, 'Makarov's Secret Power' is quite engaging as it reveals a hidden power that Makarov has and how it could potentially change the fate of Fairy Tail.
One common theme is sacrifice. Characters often give up their lives for the greater good of the guild or their friends. For example, in many stories, a hero might die to save the guild from destruction.
In some Fairy Tail fanfictions where Juvia dies, it could be a very emotional and impactful scenario. It might be due to a powerful enemy she couldn't defeat, sacrificing herself to save Gray or her friends. Her death could lead to Gray's character development, making him more determined to fight against the forces that took Juvia from him.
One interesting 'Fairy Tail Gray Death' fanfiction could be the one where Gray's unique magic is explored in more depth during a life - threatening situation. Maybe it shows how his ice - make magic could be used in unexpected ways to fight off the concept of 'death' in the story.
Well, many fanfic writers take creative liberties with Lisanna's death. Some might show it as a heroic sacrifice, where she gives up her life to save others in the guild. This could then be a source of inspiration for the other characters, pushing them to be better and stronger. Others may depict it in a more tragic and unexpected way, perhaps due to a misunderstood magic spell or an unforeseen enemy attack.
The guild would be devastated. Natsu would probably be one of the first to be enraged. He'd vow to find whoever or whatever was responsible and make them pay. His fire would burn hotter than ever as he channels his anger.
Gray would be devastated. He might go into a state of deep depression, isolating himself from the rest of the Fairy Tail guild. He would blame himself for not being able to protect her, especially if her death was related to her love for him. Gray would probably be filled with anger as well, and he would vow to take revenge on whoever was responsible for her death.
