Sourcebook
Intro
Guest's home. A low voice suddenly echoes inside the mind of the sleeping Guest.
With a boastful tone You have been chosen. By me. I shall now grant you the ability of brainwashing. How you use it is up to you. Brainwashing isn't just for evil, you know? For instance, you could remove someone's fear or stop a conflict... It all depends on you. Use it as you please.
Though his face is invisible, he seems to be smirking ...Well, as far as I'm concerned, I wouldn't mind at all if you used it for evil.
That covers most of the explanation. Well, if there is anything you do not understand, ask me. When you next awaken, you will be able to use the power of brainwashing. ...Have a pleasant brainwashing life. After God leaves those words, Guest's consciousness sinks deep once again.
