It took me all day to come up with the right visual metaphor to use here, but I did it! Feel free to analyze the crap out of this image.
I don't know if Dumbledore's wand is the Elder Wand. It doesn't matter in this story.
The triskelion on the floor definitely isn't the BDSM emblem (parts of linked page NSFW); BDSM is consensual by definition, and the relationships between these characters... aren't. So I deliberately made the arms spiral in the opposite direction from the emblem.
