Dumbledore calls Harry into his office later that day, and tries to convince Harry not to accept this challenge. But never quite comes clear as to why...and Harry is getting fed up.
Argus speaks to Harry in Terran, "Ask him about your scar and the other items that house the Dark Lords Life force."
"Alright Dumbledore, I know there is something about my scar, and some other items that have bound the life force of the Dark Lord to this planet, but I do not know anything about them, nor is there any information in your library about them. If you know anything about them, I suggest you tell me know, and help me act on it, or I can just leave." Harry having had enough of the old mans half truths and half promises says.
Dumbledore however is shocked. How did Harry find out about the Horcuxes, and more frighting, how did he know he was one? "What ever do you mean, Harry, I have not said anything of the sort."
"No you have not, you have hid behind half truths, and promises, but have not told me anything, I learned all the magic you school teaches, now are you going to tell me about them, or shall I have Captain Argus take the knowledge from you?"
"I doubt very much if he could force the information from me, only Severus and the Dark Lord are my equal in the mind arts." Dumbledore says in a haughty tone.
"There you are wrong Dumbledore, your but a novice in the true mind arts, I can take from your mind anything I want, and have taken quite a bit in this past week. I know what you call Horcuxes, that you have one, I want to see it. I also know its in the 2nd drawer from the left in your desk." Captain Argus says, speaking for the first time in days to the Headmaster.
Dumbledore, stands and brings to bear his full magical aurora, eldrich wind whipping his hair and beard wildly. "I will NOT STAND FOR YOUR INTERFENCE DARK ONE!" and whips his wand from his robe and casts a bolt of red fire at the Captain. Harry, slightly alarmed, pops up a shield between the two, then calmly says. "You do realize if the Captain here, choose, you would be dead before you would twitch that wand of yours?" Harry asks.
"As if the power of Evil can defeat me, I am the leader of the Light and can take this one Dark Creature down anytime I choose. He is not even magical, he is but a muggle and cannot harm me. Harry join me and leave this Dark one, I will teach you all the Light magic I know, then together we can defeat the Dark Lord and rule this land" Dumbledore states, as if its the most obvious thing in the world.
"Dark? Dark Angels are one of the last Defenders of the Emperor, I would lay down my life at any time in its defense, now as you do not seem to want to tell me what I want to know. I think its time I found out for myself." Captain Argus, stares into Dumbledore's eyes, and Dumbledore withers under the gaze, but cannot move, his mind is now an open book, the Captain tears down all the walls within Dumbledore's mind and takes the knowledge, all the clues as to where they are, all his plans to control the boy-who-lived, his wealth, his fame, his power, his plans to make sure that as soon as Harry gets too powerful, he is branded Dark, and killed, preferably by Dumbledore himself, so that the his own fame get more and more powerful, and he can then rule the British Wizardly world from behind the curtain and then move on to the rest of the world.
"Just as I expected, your no different from this Dark Lord, you want power, but you don't want to rule from fear, you want others to do your dirty work. So you can stay nice and popular, and do whatever you want. And by the Emperor, goats? Have you no shame man? " Captain Argus now has his own power at full strength and he glows with a halo of power. Digging a bit deeper into Dumbledore's mind. So you want to live forever as well, the energy of this castle, and that Horcux ritual you planned to do this summer would give you pretty much unlimited power, esp as you control what the next generation learns and from who. Pretty good setup, too bad I have taken down better men than you, who had both better plans, more power, and a lot more followers, with just a squad or two of Marines. I should kill you where you sit, but for now, you live. Remember this, you are NOT all powerful, I can say one word and me and Brother Harry are out of here, and this Castle is a pile rubble for real, not the petty tricks you play on the rest of your world."
Dumbledore is cringing in the corner of his office, fear plainly written on his face, as his master plan is exposed for all to hear, the portraits of the headmasters past, are shocked to hear this, and all start jabbering at once. Fawkes, trills, not his normal Phoenix song, but one of fire and brimstone, for the first time, he can see into Dumbledore's mind too, and now knows he has been tricked. A brilliant red cord appears in the air between Dumbledore and Fawkes, and snaps, Dumbledore staggers, his bond with the Phoenix broken. The castle itself seems to take the next step, and glows around Dumbledore and then the glow forms a ball, and heads out the door to find the Deputy Headmistress, as Dumbledore no longer controls the castle.
Harry and Argus start to speak, in Terran, trying to figure out where to go from here. They decide to remove the scar from Harry on the ship, Argus has spent a few days in the medical bay, figuring out how to do it, should take less than an hour. Recovery should take just a few hours as his incomplete Geneseed controlled body heals itself. But they are unsure if they can track the rest from the fragment in Harry, so they need the one the Headmaster has, it has to be destroyed anyway.
Harry withdraws a small canister from his belt, twists a knob on it, it sticks to the aforementioned drawer, and he withdraws, dragging Dumbledore with him, 10 seconds later, a ear splitting crack is heard as the Krak Grenade splits the desk in half, as well as destroying the magic on it. Argus says something and Harry withdraws a small single stoned ring from the rubble and they withdraw.
"Argus, I have a request to make, will you hear me?" Harry asks as they walk from the Headmaster's office. The formal nature of Harry's statement brings the Captain down from his fury, and his glow fades. "Yes, Brother, I will hear your request."
"I wish to request that a candidate for Dark Angel be considered from this school, and I wish to request to bring aboard another, who while not a candidate for a Dark Angel, should still be saved and their talents used to bring glory to Emperor." Harry states, his full bearing and regal statute plain for even a blind man to see.
"Bring the candidate to the ship, if you feel he qualifies I am sure he does, as to this other, who is it? And what can he do for us, outside of being a Dark Angel." Argus answers.
"It is not a him, Sir, its a female, which is the only thing that disqualifies her to be a Dark Angels, and she has not only a strong Magical power, but a sharp and organized mind that could ease a lot of the duties you now perform. I could easily see her being a historian for the Chapter." Harry replies.
"If she can handle it, I will make her a retainer of the Chapter, are you sure of this?". Argus queries.
"Sure she can handle it? Yes, and if the Codex would allow it, I would say she would make a damn fine Space Marine as well. But a retainer will do. I will see you on the ship in an hour."
"As you were, Marine, and I expect you to report in one Earth Hour exactly, not a minute late".
Fifty five minutes later, after asking Hermione if she wanted to explore space and join the Dark Angels as a Retainer, of course she was unsure until Harry said that she would be learning to read Terran and a few other ancient languages as well as working in the Chapter's archives. That sealed it, learning from books and scrolls, tens of thousands of years old, was more than enough for her to have leave this world. Harry, having already had a converstaion with the young man, slapped a transport beacon on Ron Weasley, and spoke into his throat mic. The three of them teleported to the ship in a flash.
