"You have failed me yet again. Give me one good reason not to kill you and deal with the traitor and the Gate Holder myself."
"Forgive me, Master. I shall not fail you again, I swear it."
"….You have said that before. However, I shall indeed give you one final chance to prove yourself. But this time, you shall do things my way. You must follow my instructions to the letter, lest you fail me once more."
"I want you to go to the surface, let them believe you are on their side. The girl now enters the World of Dreamless Sleep when she slumbers, but she will return. And over time, as will her memories. Let her and the traitor think you, too have betrayed me. Get them to trust you somehow. When the time is right, bring her down here and I myself shall finish what you blundered all those years ago."
"Forgive me for being so insolent Master, but how shall I gain their trust?"
"He will not be too difficult to sway, but she won't be as trusting because she will no doubt be afraid of you. We are not without a few 'tricks' so to speak. We have one ally in the Waking World who is willing to see the Gate Holder suffer. You ought to know of whom I speak. Now go. And as I said, this is your last chance. Do NOT fail me again, should you forfeit your existence."
(a/n: sorry the prologue is so short. The first chapter will be longer, I promise.)
