Canon Voldemort killed his own father. Since he was already planning to make the horcruxes anyway (or perhaps that was how he started? I forget.) what I would have done in his place was secure some of his bone at that time so I would have it available I case I ever had need to revive myself.
Of course, I would also have had Bellatrix donate some flesh, which I would keep frozen somewhere inconspicuous, unless the recipe actually requires that it be fresh.
I think Voldemort would have been staggeringly stupid NOT to have kept a remnant of his father's body given how much blood magic requires these types of ingredients.
- This thread has run its course. You will find newer threads in the discussion section.
Another discussion thread - the fourth - has reached the (arbitrary?) 500 comments threshold, so it's time for a new thread for Eliezer Yudkowsky's widely-praised Harry Potter fanfic.
Most of the paratext and fan-made resources are listed on Mr. LessWrong's author page. There is also AdeleneDawner's collection of most of the previously-published Author's Notes.
Older threads: one, two, three, four. By tag.
Newer threads are in the Discussion section, starting from Part 6.
Spoiler policy as suggested by Unnamed and approved by Eliezer, me, and at least three other upmodders:
It would also be quite sensible and welcome to continue the practice of declaring at the top of your post which chapters you are about to discuss, especially for newly-published ones, so that people who haven't yet seen them can stop reading in time.
