[null and void]

How does V get out of a locket or ring to do anything?

I think wearing it allows the wearer to be taken over.

More to the point, what good does making them nearly impossible to acquire serve?

What happened to DD hand?

Better to hid, so no one can destry them, and V can manipulate the Death Eaters enough to get any of them to collect it. The farther apart they are, the better his chances of never dying, and isnt that the point of doing that?
