For example Alcina Dimitresku

People who fear large big houses with someone immortal chasing you will be very uncomfortable playing that part of a game!

For Donna Beneviento it's simple

People who fear darkness and dolls will be really scared

Same goes for Salvatore Moreau(miranda simp)

He symbolise a something unreal and ugly

Also that eyes on his back-

It's really uncomfortable even for me

And finally karl Heizenberg

People who fear a big factories with robots killers will be... well you understood

So each of the lords scare specific type of people

It's really interesting theory, what do you think?

Or that's all was already revealed and I am degenerate..?
