A plot could be centered around Shirou summoning Morgan to help him in a magical tournament. Morgan, being a powerful figure, has her own motives for participating. Along the way, Shirou discovers that Morgan has a connection to his past that he was unaware of. As they compete in the tournament, they face opponents who force them to work together and rely on each other's strengths, leading to a deeper understanding between them.
Their relationship could develop in an interesting way. Since Shirou is often self - sacrificing and Morgan is a powerful and complex character. When Shirou summons her, she may see him as a tool at first. However, as she witnesses his unwavering beliefs and courage in the face of danger, she might start to soften towards him. Maybe she begins to protect him in battles, and they start to share their thoughts and feelings, slowly building a deeper connection.
One interesting fanfiction could be where Saber summons Shirou in a modern setting with a twist. For example, instead of the usual Holy Grail War context, it's in a world where magic is more commonplace. Saber might summon Shirou to help her with a different kind of quest, like saving a magical artifact from being misused. The story could explore their relationship development outside of the typical war scenario.
One interesting plot could be Shirou and Medusa teaming up to face a powerful common enemy. Maybe an ancient evil that threatens the world they are in. They would combine their unique abilities, with Shirou's projection magic and Medusa's powerful combat skills and snake - based powers.
Another plot could involve the reborn Arthur Morgan exploring parts of the game world that were not fully discovered in his first life. He could encounter new characters or hidden treasures, and this new knowledge could change his perspective on the world around him and his role in it.
There could be a fanfiction where Shirou Emiya discovers a long - lost family member who is also a powerful mage. The story could revolve around their relationship, how they learn from each other, and how they face challenges together. Or perhaps a plot where he has to use his powers to enter a magical realm and retrieve a powerful artifact to save his world from destruction.
Another theme is the idea of destiny. Often in these fanfictions, their being summoned together is seen as part of a greater destiny. For example, in some stories, they are meant to save a certain world or defeat a powerful enemy. It gives a sense of purpose to their relationship. Also, the theme of self - discovery is quite prevalent. As they face challenges together, they learn more about themselves and their own powers. This is especially true for Shirou as he often discovers new aspects of his abilities when paired with Arturia.
One interesting plot could be Saber Lily and Shirou teaming up in the Camelot era to face a powerful, previously unknown threat. Maybe a dark sorcerer who is trying to corrupt the very essence of Camelot. They would have to rely on each other's strengths, with Shirou's determination and Saber Lily's combat skills.
Another plot could involve a love triangle where Shirou is caught between his feelings for Fem Gilgamesh and another character. This would add a layer of drama and conflict as he has to navigate his emotions and the complex relationship dynamics. Fem Gilgamesh, with her pride, would also have to face the idea of competing for Shirou's affection.
One common plot is them solving a difficult case together and their bond growing stronger through the process. For example, in some fics, they might be the only ones who notice a crucial detail that others miss, and this shared discovery deepens their friendship. Another plot could be one of them getting injured on a case and the other being extremely protective and caring.
