The One Who Murdered Slain for Their Blood.

I was reading up on Elizabeth Bathory, and I know read her article a few years back, but I came back to it and wanted to remember it for later. She was a royal back in the 16th century in current day Hungary, where she was obsessed of looking young forever. To this end, she had murdered and slain over 300 young girls and poured their blood into a bathtub where she would soak in it, in the hope this would keep her young. Because of her high nobility, she herself was not sent to death or chained in prison, but was to be house arrested in her castle for the rest of her life. She's the real life processor to mystics like Dracula and vampires. So I thought, that's pretty cool.
