Alec and Magnus Bane's love story is really beautiful. They are from the 'Shadowhunters' world. Their relationship started with a bit of hesitation from Alec due to his Shadowhunter upbringing. But Magnus's charm and his own growing feelings led to a deep and passionate love. They faced many challenges together, like dealing with the prejudices of the Shadowhunter society against warlocks. Their love overcame all these difficulties and became a symbol of love that transcends boundaries in that fictional universe.
Definitely their wedding. It was a huge step for both of them, especially considering the challenges they had faced. It was a celebration of their love in the face of all the odds. Also, the time when Alec stood up to his family and the Shadowhunter society for Magnus was really powerful.
One of the most popular themes is the exploration of their cultural differences. Magnus being a warlock with a long and rich history and Alec being a Shadowhunter from a more traditional background. Another theme is their struggle against prejudice. They face discrimination from the Clave and others due to their relationship. Also, the theme of sacrifice is common, like how they would sacrifice for each other's safety and happiness.
Love and acceptance are very common. Given that they are from different worlds (Shadowhunter and warlock), their relationship often involves them learning to accept each other's differences. Another theme is family. Alec has his Shadowhunter family and Magnus has his own kind of 'found family' among the Downworlders. Fanfictions often explore how their relationship affects and is affected by their respective families.
They might love fanfiction because it offers different perspectives on their relationship. Fanfictions can explore aspects that might not be fully covered in the original works.
One great Magnus Bane and Alec Lightwood fanfiction is 'The Bond Beyond Magic'. It beautifully explores their relationship, delving into how their different personalities complement each other. Another is 'Alec's Discovery' which focuses on Alec's journey of self - discovery within the relationship. And 'Magnus' Heart' shows Magnus' perspective and his deep love for Alec in a very touching way.
One common way could be through using his magic in a subtle way. For example, he might use magic to create situations where Alec has no choice but to follow his lead. Maybe he makes it seem like the only option for Alec to protect his friends or family is to do what Magnus wants.
There are also Tumblr blogs dedicated to sharing Alec Lightwood x Magnus Bane fanfiction. You can search for relevant tags and find some really unique and creative works that might not be as mainstream as those on AO3 or Fanfiction.net. These can offer fresh takes on their relationship, such as exploring how they handle cultural differences between the warlock and Shadowhunter worlds.
There might also be fanfictions that focus on their roles in the wider shadowhunter world. For example, ones where they have to make important decisions regarding the safety and future of their community, while also maintaining their relationship. This type shows how their love can be a strength in more than just a personal sense.
One common theme is acceptance. Alec has to come to terms with his feelings for Magnus in a world that may not always be accepting, and Magnus has to accept Alec's insecurities and growth. Another theme is sacrifice. They often have to sacrifice personal desires for the greater good of their relationship and the Shadowhunters world.
