Mulling it over, she was right. The Hogwarts wards are known to me. I was one of the many who placed our mark on them, on a part of Hogwarts. I’m pretty sure students were still doing that towards the end of my first life. "I might have to see about doing that. I’m sure they haven’t been touched for quite some time." Though it would be tricky to do that without being in the Headmaster’s office. The only other place where one could do that was in the Chamber of Secrets where the majority of the ward stones were located.
