Alec and Magnus are the central characters in this fanfic concept. Additionally, we might see some of their old friends in new lights. Jace could be more involved, trying to mediate between Alec and Magnus. Maia, the werewolf, could also be a character who offers Magnus a different perspective on relationships. And perhaps a mysterious figure from Magnus' past, like an old mentor, could show up to help Magnus move on from Alec or, ironically, help him get back together with Alec.
Obviously, Alec and Magnus are the main characters. But new characters could also be introduced. For example, a new Shadowhunter trainee who looks up to Alec and tries to help him get over Magnus. Or a powerful warlock from another dimension who becomes Magnus' friend and tries to show him that there are other options besides Alec. There could also be a seer who predicts that Alec and Magnus are meant to be together and tries to nudge them in the right direction.
The main characters would be Alec and Magnus, of course. However, we might see the introduction of some of their family members more prominently. Alec's siblings could play a bigger role, like Izzy trying to comfort Alec and give him relationship advice. Magnus' father could also be introduced, perhaps coming to check on his son after the break - up. And then there could be a character like a mundane who gets caught up in the Shadow World because of Alec and Magnus' break - up and ends up being a key figure in bringing them back together.
One reason could be miscommunication. Maybe they didn't fully understand each other's needs and wants. For example, Alec might be too focused on his shadowhunter duties and not give enough time to Magnus, who would then feel neglected.
Well, one possible plot development could be that they initially avoid each other. Alec might throw himself into his work with the Shadowhunters, trying to forget Magnus. Magnus, on the other hand, could start traveling to different magical realms to distract himself. But as time passes, they might start to cross paths again, perhaps due to some common threat to the Shadow World. And slowly, they might start to remember the good times they had and question if the break - up was really the right decision.
Some fanfics might show Alec being very stoic at first, hiding his pain. He's used to bottling up his emotions as a shadowhunter. But later, he might break down in private. For Magnus, he could be more openly heartbroken, showing his emotions through his magic, like making the room around him dark and stormy.
Maybe there was a big misunderstanding or some external pressure that made Magnus act that way.
The main characters are Alec and Magnus. Alec is a Shadowhunter, and Magnus is a powerful warlock. They are the central focus of the fanfic set in the City of Glass.
Obviously, Alec and Magnus are the main characters. Alec is a Shadowhunter, known for his loyalty and his growth from a more reserved person to someone more open - minded. Magnus is a powerful warlock, flamboyant and full of magic and mystery.
It's also possible that the real antagonist is Alec's own insecurities. Magnus might be using Alec's insecurities to manipulate him. So in a way, Alec's internal struggles could be seen as the antagonist. But again, from the title's perspective, Magnus is the one directly involved in the act of manipulation.
It could be another warlock who doesn't like the idea of Alec, a Shadowhunter, getting involved with Magnus and his family.
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.
One characteristic is the focus on the relationship between Alec and Magnus. It could be their romantic relationship, like in many fanfics where their love story is explored in great detail. Another is the exploration of their individual personalities. For instance, Alec's loyalty and Magnus's magic are often highlighted.
