If that doesn't inspire a lot of really amazing fan art, I don't know what will. Especially, I think they will want to draw the image of the long red hair binding the young man's limbs, violets in riotous contrast through the whole amazing mess of it--very visual. I thought the dub con was appropriately disturbing--it does add toward an answer to the canon question, "why did Albus feel so guilty about loving Grindelwald?" Plus you did a great job with the period language--"invert," good choice.
