JAMES POTTER AND THE VAULT OF DESTINIES

       'Don't you worry about it,' Harry told him when James asked about it. He smiled at his son, but James could tell that it was a thin smile, put on mostly for his benefit. 'You just keep at your schoolwork and your Clutchcudgel. Keep an eye on your brother too. Your mother and I are a little worried about him and those new friends of his in Werewolf House.'

       James shrugged and nodded. His dad was masking his larger worries with concerns about how Al might be fitting in with his fellow Werewolves. It was rather unsettling, but James determined not to make it his problem. He had done that enough over the last two years.

       'I've heard of this Professor Magnussen bloke,' James told Ralph and Zane the following weekend, walking along the cold flagstone footpath and kicking piles of dead leaves. 'Back during our first year. Remember when I told you about sneaking out with the Invisibility Cloak and following my dad and Chancellor Franklyn around during their midnight meeting? Franklyn said something about Magnussen, made it sound like he was a real trouble maker. Compared him to that Umbridge witch that Dad told us about from back in his own day.'

       'That's pretty bad,' Ralph considered, frowning slightly. 'I remember those stories.'

       'But Magnussen's the key to the whole thing!' Zane insisted. 'He's the one that found the key to the Nexus Curtain. We could look him up in the Archive, maybe figure out how he did it! If we did that, then maybe we could follow him through into the place between the worlds and find whoever it was that attacked the Vault of Destinies!' Zane's eyes boggled with excitement, but James sighed.

       'You're a complete nutter,' he said dourly. 'We're done with that kind of thing, all right? Ralph and me, we got it all out of our system last year, chasing down that horrible Gatekeeper thing. Rose too. If she was here, she'd probably cuff you on the ear even for bringing it up.'

       'Hah,' Zane replied, unperturbed. 'I've spoken to Rose about it already through the Shard. She thinks it's worth checking out at least. So there.'

       Ralph spoke up uncertainly. 'She says we should just tell James' dad about it and let him look into it. It's his job, after all.'

       'Mr. Potter's got his hands plenty full already,' Zane answered breezily. 'I've heard he's getting loads of flack from the local authorities, especially the Magical Integration Bureau. They're making things pretty tough for him, keeping him out of the loop.'

'What?' James exclaimed angrily. 'Where'd you hear that?'

       'I eavesdropped on your dad and Chancellor Franklyn in the Kite and Key after Al's last Quidditch match. Some of us don't need any Invisibiliy Cloaks to pull that off.'

       James was rankled. 'But why would the local authorities shut him out? He was sent here to help them, wasn't he?'

       'Apparently they're suspicious of him,' Zane replied. 'Remember, here in the States, the Progressive Element is all over the place. Not everyone believes all that drivel about how Voldy was just a revolutionary thinker and a champion of the people, put down by the magical ruling powers of the day, but enough idiots do believe it that it makes trouble for people like your dad. They think he himself might even be behind some of that W.U.L.F. stuff. Apparently, they questioned him about the disappearance of that Muggle politician and the Chrysler Building. They even think he might have been in on the attack on the Vault of Destinies, especially since the missing thread managed to vanish without a trace and they've had no luck tracking it down, even though it'd leave a magical trail a mile wide. They think that your dad hasn't found the thread yet because maybe he doesn't really intend to. Like maybe he's covering for his own cronies or something.'

       'That's idiotic!' James fumed. 'He's here to rout out the gang that did that stuff and stick them all in Azkaban!'

       Ralph was thoughtful. 'Well,' he said slowly, 'I'm not saying they're right, of course, but if he was involved with a group like the W.U.L.F., it would probably be the perfect cover for him to be on the team that was supposedly meant to investigate them. If you think about it from the Progressive Element point of view, that is.'

       Zane was impressed. 'All that time you spent on Corsica's debate team really sunk in, didn't it, Ralphinator? You can think just like them when you need to.'

       'That's idiotic,' James said again, kicking at a particularly large pile of leaves.

       'The Progressive Element is idiotic,' Zane replied. 'Once you believe in that kind of stuff, other stupid stuff becomes a lot easier to swallow.'

'But why would they think my dad would ever join such a bunch of awful people?'

'Ah,' Zane said, smiling ruefully. 'That's an easy one. A lot of Americans think that the W.U.L.F. is just a puppet organization, run by the Ministry of Magic and, specifically, the Auror Department itself. They think that it's just a big scare tactic, meant to keep people afraid and willing to keep living with the old laws of Muggle-magical separation and all that.'

       Ralph shook his head. 'They must think people like James' dad are a bunch of really twisted sneaks then.'

       Zane nodded.

       The three boys stopped as they neared the Octosphere. The big black orb floated in its watery bed, which was now pasted with dead leaves. A dull, nearly inaudible rumble came from the slowly revolving stone.

       'According to legend, Professor Magnussen invented this thing,' Zane commented, resting his foot on the low stone wall that surrounded the pool. 'Did you know that?'

       'How do you invent a big black ball?' Ralph asked quizzically.

       'It's not just a big black ball, you knucklehead,' Zane replied. 'It's an answer machine. You ask it any question you want and it'll tell you the answer.'

       'That's some pretty serious magic,' James admitted grudgingly. 'Are the answers always right?'

       'Always,' Zane nodded. 'But they're never helpful. That's probably why it's right out here in the open, for anyone to use. If the answers were useful, this thing would probably be the most valuable tool in the whole magical world. You can bet that that's what old Professor Magnussen meant for it to be, if the legends about him are true.'

       'Why aren't the answers useful?' Ralph asked, peering closely at the slowly revolving stone sphere.

       Zane shrugged. 'It's all quantum. Magnussen was President of Igor House, a century or so ago, and he was apparently a super genius about technomancy. He was a big believer in this thing called the Wizard's Grand Unification something or other.'

       'Yeah,' James said, warming to the subject. 'Franklyn talked about that when he took us on the tour of the Archive. It's called the Wizard's Grand Unification Theory. He says that people used to believe that if you could measure everything everywhere, then you'd be able to predict the future. And if you could predict the future, then basically…'

       'You could control it,' Zane finished. 'Yeah, that's how I heard it too. Apparently, Magnussen was crazy about it. He spent his whole life refining the theory, trying to make it work. The legend is that he used some really horrible methods, although nobody seems to know what they were, exactly. At any rate, this is one of the things he invented along the way. It uses the Grand Unification whatsit to tell you the answer to your question. There was some big flaw in the design, though, so that while the answer you get is technically right, it's almost always completely useless. Watch.'

Zane turned to the slowly revolving stone orb. In a loud, carefully enunciated voice, he said, 'Oh great mystical Octosphere, will Zombie House win this year's Quidditch tournament?'

       James and Ralph leaned forward over the low wall that surrounded the pool, watching the sphere. After a few seconds, the sphere settled to a stop, and something seemed to move within it. Blurry white shapes swam up from the inky depths of the orb, solidifying until they reached the surface and became words. The three boys stared
