I feel like a lot of people forget that Krul and Ferid's(From ONS or SOTE) names are actually based on real people.
Ferid Bathory = Elizabeth Báthory
Nádasdy aka. Countess Dracula.
Elizabeth is said to have killed at least
600 of her servants but this number
may be exaggerated.
Krul Tepes = Vlad Tepes aka. Vlad Ill,
Vlad the Impaler(Tepes in Romanian), and Vlad Dracula(Son of the Dragon).
Vlad was a sadistic leader who was
directly responsible for the deaths of 80,000 people.
I'm going to go into a lot of gruesome details so if you don't want to hear about it, SKIP IT
Vlad the Impaler had many torture methods but as you may have guessed, his favorite method is the one in his name. To torture his victims, Vlad would place a sharpened pike up their rectum before setting the pike upright. As gravity did its thing, the person would be pulled down and eventually the pike would exit through the abdomen, chest or neck. He would have these people on display to warn enemies of what he would do to them. For more information, I suggest this link: https://www.britannica.com/biography/Vlad-the-Impaler
