The Engineer
A mysterious figure who calls Oswald Mandus over the telephone, telling him that his children are trapped inside a great Machine underneath his mansion. He tells Mandus that he needs to go into the machine, restore the power, and repair it so his children can be set free. But it slowly becomes clear that The Engineer has his own reasons for wanting the machine repaired…
"Precious Eagle Cactus Fruit… help us"
"Quickly, quickly the air is thin. Their little faces turn blue Mandus. They suffocate! They suffocate!"
"MORE PIG! MORE PIG!"
