"As you say," said the green-lit silhouette. "We will establish our own Science, a magical Science, and that Science will have smarter traditions from the very start." The voice grew hard. "The knowledge I share with you will be taught alongside the disciplines of accepting truth, the level of this knowledge will be keyed to your progress in those disciplines, and you will share that knowledge with no one else who has not learned those disciplines. Do you accept this?"
"Yes," said Draco. What was he supposed to do, say no?
"Good. And what you discover for yourself, you will keep to yourself unless you think that other scientists are ready to know it. What we do share among ourselves, we will not tell the world unless we agree it is safe for the world to know. And whatever our own politics and allegiances, we will all punish any of our number who reveal dangerous magics or give away dangerous weapons, no matter what sort of war is going on. From this day onward, that will be the tradition and the law of science among wizards. Are we agreed on that?"
"Yes," said Draco. Actually this was starting to sound pretty attractive. The Death Eaters had tried to take power by being scarier than everyone else, and they hadn't actually won yet. Maybe it was time to try ruling using secrets instead. "And our group stays hidden for as long as possible, and everyone in it has to agree to our rules."
"Of course. Definitely."
There was a very short pause.
"We're going to need better robes," said the shadowy figure, "with hoods and so on -"
"I was just thinking that," said Draco. "We don't need whole new robes, though, just cowled cloaks to put on. I have a friend in Slytherin, she'll take your measurements -"
"Don't tell her what it's for, though -"
"I'm not stupid!"
"And no masks for now, not when it's just you and I -" said the shadowy figure.
"Right! But later on we should have some sort of special mark that all our servants have, the Mark of Science, like a snake eating the Moon on their right arms -"
"It's called a PhD and wouldn't that make it too easy to identify our people?"
"Huh?"
"I mean, what if someone is like 'okay, now everyone pull up their robes over their right arms' and our guy is like 'whoops, sorry, looks like I'm a spy' -"
"Forget I said anything," said Draco, sweat suddenly springing out all over his body. He needed a distraction, fast - "And what do we call ourselves? The Science Eaters?"
"No," said the shadowy figure slowly. "That doesn't sound right..."
Draco wiped his robed arm across his forehead, wiping away beads of moisture. What had the Dark Lord been thinking? Father had said the Dark Lord was smart!
"I've got it!" said the shadowy figure suddenly. "You won't understand yet, but trust me, it fits."
Right now Draco would have accepted 'Malfoy Munchers' as long as it changed the subject. "What is it?"
And standing amid the dusty desks in an unused classroom in the dungeons of Hogwarts, the green-lit silhouette of Harry Potter spread his arms dramatically and said, "This day shall mark the dawn of... the Bayesian Conspiracy."
