So, I was listening to this song and it gave me this idea about Deamus's wedding. I know, the song doesn't exactly fit in lyrics wise, but the whole melody and at that moment, it seemed fitting to me. Also, I love this song.

It was raining outside, the wind was brutally bowling and a thunderstorm unfolded its mightiness. This didn't concerned the young people gathering around in number twelve, Grimmauld Place the slightest. In fact, they didn't even notice what was going on. All their attention was focused on the happy couple standing in the middle of their small circle. They didn't even notice the people moving in their paintings and whispering to one another. But then again, every witch and wizard was so used to that, they simply ignored the strange behavior of paintings. They had more important things to witness now. They weren't just standing there, forming a circle around three of them cause they felt like it. They did it because it was the wedding of Seamus Finnigan and Dean Thomas. It hadn't been a surprise to anyone when they finally came together, nor when they announced their engagement. Still, their friends were more than happy for them. Those two were everyone's favorite, easy to be around and always a smile upon their lips.
When they wanted to decide who would be their best man or women it had been impossible to choose one over the other. That was why they choose all their friends. After all they were the only ones they wanted to attend.
So that was why they were gathered around them in a loose circle, holding each others hands. Only Neville was joining the couple inside the circle, being the official at this wedding. Everyone had been ecstatic when the learned that Neville's family traditionally inhibited this role and he therefore had been allowed by the ministry to fulfil this role. And he did it brilliantly. The shy, normally quiet boy flourished, he was made for this role. After his speech everyone had tears in their eyes and they vowed to themselves that only Neville was going to do their own wedding. It was the perfect ceremony. Every thing was light and beautiful. Luna decorated the whole house in colourful flowers, plants, ribbons and bows. She also brought some real fairies, fireflies, different birds, even some very exotic ones, rabbits and even a unicorn with it's foal. The once so gloomy house now resembled an enchanted Forrest. The whole ceremony couldn't be more magical. After it was done, the friends congratulated the happy couple and the feast started. Molly Weasley and Kreacher outdid themselves. Pastries, cakes, casseroles, salads, cupcakes, everything imaginable was there. In a corner an enchanted orchestra was playing, Hermione's contribute to the celebration. Everyone was dancing, eating and laughing and no one cared about the raging storm outside.
