This is fan art for Harry Potter and the Methods of Rationality.

It is unusually high quality Harry Potter fan fiction, and teaches you as you read it. It was engaging enough to upset me when I got to the end and realized it was incomplete.

Draco and Lucius' re-explored relationship is one of my favorite parts of this story. Completely ruthless people can love just as tenderly as conventionally moral ones. I originally intended to have the Patronus curled affectionately about the cane, but then I decided this expression of Draco's soul would have more of a sense of decorum, and that loving, awe-touched admiration is a more apt expression of his feelings for his father than straight up cuddles.

The pictures I found of the Blue Krait tended to have it being mostly blue with pale stripes, but I think reversing the coloration makes it more appropriately silver and glowy. And it's no loss to the snake since I expect the Patronus is largely unconcerned with being able to hide in tall grass.
