Hannibal was honored to have been invited. He hadn't known what to expect aside from that this was going to be one of the most unusual weddings he would ever see in the whole of his life. He wouldn't have said no anyway, but since it was Baba Yaga, he very much wanted to be there.
The aesthetics weren't quite what he would have imagined if he'd been asked about it. Of course, his perceptions of what a vampire would choose were lightly skewed by what the humans around him portrayed them as. In the end, however, it was very lovely to behold, and both parties appeared to be very at home in the moment.
He could see in their eyes, in their movements, that they really meant this thing they were doing.
Hannibal bowed his head lightly at the groom, and then smiled softly at the bride as she approached.
