Luna

I hit quote & reply before I really grasped what you said.
I was going to say that no, it can't be anything inside the school...

But a decendant, or just a major fan -- could be.
Any interest or hobby or obsession Luna takes on would be thoroughly beaten into the ground.
Whatever it is, if it's anywhere within her reach, she'll have it.

Yeah, I can totally she her having tons of stuff that was once Rowenda Ravenclaw's. I mean she really cares about what she believes and I think that she would also really care about her ancestors, ya kno. Maybe not but it is a cool idea.

Was it mentioned in book 6 what the thing Rowena had could be? I can't remember now.

No, they just said something of Ravenclaw's, but nothing specific.

Dumbledore said it MIGHT be something of Ravenclaw's. Just a guess.

Yeah, he didn't know if Voldemort had ever tracked down anything of Ravenclaw's. What if he didn't? What object would that horcrux be then?

Maybe the trophy that Voldemort got in Hogwarts.

It should be distroyed anyway just to make sure.

Yeah it should be. But wasn't it mentioned in book 6 as a possibility? I can't remember now.

I think that Dumbledore mentioned it but said it was unlikely, but all the same anything that gives Voldemort an award should be destroyed because he no longer deserves recognition, ya kno.

After everything that he has done.

But of course, he was very attached to the school and might go after the person that destroyed anything there that was awarded to him.

I am 99% sure that it did not say anything about Riddle's trophy. My thinking, from the very beginning, has revolved around the idea that Dumbledore hasn't thought of the trophy in years. If book six has anything to say about it, I would have noticed by now.
