One common theme is his magic and power. Writers often explore how Magnus uses his magic in different situations. Another theme is his relationships, like his romantic relationships or friendships. His backstory also features a lot, especially his experiences growing up as a warlock.
Magnus would likely use his powerful magic. He could create wards around the place where Harry is staying. These wards would be strong enough to keep out any dark wizards or creatures. He might also give Harry a charmed amulet that has protective spells on it.

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.
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.
They might become more confident in their relationship. Alec could start to be more open about his feelings, not just towards Magnus but also to his friends and family. Magnus, on the other hand, might feel more secure and start to share more of his past and secrets with Alec.
I'm not sure exactly as I haven't read it. But it might be about a 'dark angel' and what happens in a post - dark world. It could involve themes like good and evil, survival, or redemption.
