These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way.

Complete Monster: Cyrus Kriticos is a millionaire occultist and ghost hunter who will stop at nothing to become the most powerful man on Earth. He builds a huge mechanical device designed in the 15th century called the Ocularis Infernum (The Eye of Hell) which will give its bearer infinite power and is actually the glass house he supposedly bestows on Arthur and his family. He captures 12 tormented spirits, trapping them in the basement of his mansion with magic sigils to drain their souls and fuel the engine. One of the ghosts includes his nephew Arthur Kriticos' deceased wife Jean, who tragically died in an apartment fire years ago. He lures his relatives to the device because he needs his nephew to sacrifice himself and become the 13th ghost to complete the ritual. He kidnaps his nephew's teenage daughter and younger son and puts them in lethal danger to manipulate his nephew. His lover Kalina had been spying for him as a double agent on a good occult organization who tried to stop him and helps him manipulate Arthur. When she balks at putting the children in such danger he has her crushed between two compacting walls without a second thought.
Which makes things a bit Hilarious in Hindsight when you think about it, considering he went from portraying one character getting mixed up with ghosts to one of the best known fictional characters for doing so (whether they be real or not).
