One idea could be to focus on the magical preparations. For example, the enchanted flowers that sing and change colors to match Lily's mood. Another could be the presence of their friends from Hogwarts. Maybe Sirius is the best man and he plays a prank on James right before the ceremony, but in a light - hearted way that adds to the fun. Also, the wedding venue could be a hidden magical garden filled with magical creatures like thestrals and unicorns that are visible only to those pure of heart, making the wedding truly magical.
Petunia could be an important character. She might be grudgingly attending the wedding, still having mixed feelings about Lily's magical world. Her presence could add some tension as she struggles to fit in. And then there's Dumbledore. He could make an appearance and give some wise words of advice to the couple, perhaps about the future challenges they might face together.
One possible plot could be about the elaborate preparations for the wedding. It might include details like choosing the venue, which could be a magical place like Hogwarts' grounds. Friends like Sirius and Remus could be involved in pranks during the pre - wedding jitters. And Lily might be having a hard time choosing her wedding dress, with her friends helping her out.
One great 'lily and james potter fanfic' is 'The Potter Legacy'. It beautifully portrays their relationship and the challenges they might have faced. The characterizations are on point and it adds a lot of depth to the Potter family's backstory.
Well, think about the Hogwarts houses. James is in Gryffindor and Lily is also a Gryffindor. The house pride and the friendly (and sometimes not - so - friendly) competitions between Gryffindor and other houses could play a role. Maybe they first started to really notice each other during a big Gryffindor - Slytherin rivalry event. And then there are the classes. In Potions class, they could have had to work together on a difficult potion. At first they might have bickered, but then gradually fell in love as they realized they complemented each other well. Also, the Triwizard Tournament, if it happened during their time at Hogwarts, could have provided a backdrop for their relationship to develop. They could have been involved in different tasks, supporting each other and showing their love through their actions.
In some fanfictions, a plot twist could be that Voldemort tries to attack during the wedding. This adds a whole new level of danger and drama to the story. It forces James and Lily to rely on their friends and their own magical abilities to protect everyone at the wedding.
One great piece of Lily and James Potter wedding fanfiction is 'A Potter's Wedding Day' on FanFiction.net. It beautifully captures the essence of their relationship and the grandeur of the wizarding wedding. The author details the traditional wizarding elements like the use of magic in the decorations and the presence of magical creatures at the event.
I really like 'The Marauders' Era: Lily and James'. This fanfic does an amazing job of capturing the essence of the era they lived in. It has great descriptions of Hogwarts during their time, and the interactions between Lily and James are very well - written. You can really feel the chemistry between them as they go through various adventures together in and around Hogwarts.
One common theme is love. Their love story is often at the center, showing how they overcame differences (like James' initial arrogance) to fall in love. Another theme is friendship, as they are part of the Marauders' group. Their loyalty to their friends and how that affects their relationship is often explored.
They would surely feel a great deal of love. After all the challenges they faced to be together, this night is the culmination of their relationship. There would also be a sense of relief. Knowing that they are now bound together in marriage, they can relax and fully embrace their relationship without the fear of being separated.
