Zayan's Advice

What happened to Caesar? She was someone you could count on. Her replacement, Amadeus, is nothing but a dumb machine. I can't get anywhere with him. No matter what I do, he won't shut off the beam apparatus without a password. I'm running out of options!

Maybe Zayan could think of something?

The vampires made sure that no one could shut off the beam apparatus without their say-so!

From what I can understand from your story, the new spirit of Darkblood Citadel lacks any emotion or autonomy. It is but a machine to perform tasks, much like a June golem. It is impervious to bribes or arguments. Breaking into its consciousness is not an option either - no one alive can do that to these spirits. What are we going to do?!
