What a deep, full bodied world you created! I loved how you constructed the magic - the collar, the wards, sympathetic magic, all of it.
And such great OCs! I love Madame Lalique! She was such a vivid character, and how she slipped clues and knowledge to Harry was so Slytherin.
You made the war a real thing of horror that doesn't just end when peace comes. We, and Harry, watch as each person in his life finds a way to heal and move on, always leaving him behind.
You created such an intricate plot with Harry needing to be freed before Severus could be. So bittersweet for Harry to finally be able to feel again and be himself again, only to have to release the one he loves. Thank you for the hint of hope at the end.
