This is a major crossover form Harry Potter to as many other stories as I can manage, I will try to write a summary of each character and world before every chapter.
Chrestomanci is in the book Witch Week, Charmed Life, Angles of Caprona, The Lives of Christopher Chant, and Mixed Magics, by Dianna Wynne Jones. Chrestomanci is the title given to the regulator of all worlds, and anyone can talk to him or ask him for help by saying his name.
He has nine lives, because the alternate versions of him in other worlds don't exist. (If you need more details on this theory or have any questions e-mail me at Often the Chrestomanci is well dressed and attacks problems in a thoroughly logic and stubborn way.
When Lupin arrived almost a half hour later Harry had just finished telling Ron and Hermione what had happened and had handed Hermione the piece of parchment with the spell on it.
"Drop that!" Lupin shouted, and Hermione jumped nearly ten feet in the air, surprised by the sound of his voice. Guiltily she dropped the piece of paper.
"What's wrong Lupin? Why are you so angry about it?" Harry demanded.
"Where is Chrestomanci?"
"You mean that man? He left with the weirdest Apparation spell I've ever seen," Harry replied, still very confused.
"He is the Chrestomanci, regulator of all magic in all worlds, a good friend of Dumbledore and the last person we want to talk to right now," Lupin said, once again his calm and collected self.
"Why?" Ron asked. "Why don't to talk to him now?"
"Because he's very busy, and if we call him now when we don't need him he might not respond when we do."
"Need him? What do we need him for?" Hermione asked.
"For an army," Chrestomanci said, as he Apparated in front of them with a puff of smoke.
"What army?" Harry was beginning to wonder whether he would ever understand what was going on again.
"Who are you?" Chrestomanci peered at Harry.
"That's Harry Potter, Chrestomanci," Lupin said. Suddenly Chrestomanci's whole demeanor changed. He suddenly looked ashamed.
"Oh sorry, Harry. I didn't mean to be rude to you, I was just shocked about Dumbledore's death," Chrestomanci apologized. Harry nodded. He understood that bit at least, on with unraveling the rest of this.
"What army-" Harry began, but Lupin broke him off.
"He's not ready for his army, Chrestomanci. Harry just accidentally got a hold of that summoning spell," Lupin said.
"What army?" Harry asked, feeling more frustrated than ever.
"The army to fight your villain, what's his name… Vittermore? Waltermort?"
"Voldemort," suggested Hermione in that helpful way of hers.
"That's it!" said Chrestomanci, snapping his fingers.
"Either way, Harry is not ready to fight Voldemort. He barely finished finding the last Horcrux," Lupin argued.
"Wait wait wait," Harry said, feeling he was just starting to grasp what they were talking about. "Where would an army come from? Every wizard outside the Order of the Phoenix has been bullied or bribed into Voldemort's army."
"Well, from other worlds, of course. That's why you need me."
"But Harry isn't ready to build an army to fight Voldemort," Lupin insisted.
"Why not?" Harry asked, feeling that this had gone far enough. It was already pretty bad that they took forever to tell him that he had an army waiting for him, and now Lupin wouldn't even let him decide if he wanted it.
"I finished with the Horcruxes, and when am I going to be ready? If you're worried about my fight with Voldemort, don't be. Voldemort has had years more experience, and I don't have enough time to learn enough things to beat him. All I can do is go after him as hard and as fast as possible. Going sooner rather than later is better."
Lupin looked as though he wanted to argue, but then he just smiled.
"Sometimes you really remind me of your father, Harry," he said ruefully.
"Well are we ready to go?" Chrestomanci asked.
"Where?" Ron asked warily.
"Well, I think we should go to Derkholm first, and then we'll be off." No one bothered to ask him what he meant by that.
"Where are we going to put all them? I mean an army isn't exactly inconspicuous," Hermione pointed out.
"Well, most of them will be like Harry, the most important and best fighters in their world, so we will probably fit in the bulk of this house. The main part can probably fit into an extended part of the house, once you stretch it."
"Stretch it?" Hermione asked, completely in the dark. "Oh, you mean with a spell. Yes that would work."
"Well are we ready to go?" Chrestomanci said as if he did this every day. Perhaps he did. Feeling dazed, Harry nodded, and, with a rush of smoke, Harry, Ron, Hermione, Lupin and Chrestomanci arrived on a sunny hillside.
I know that I kind of left Ron and Hermione out of this chapter. Don't worry; they'll soon have their own parts to play. Also, Derkholm is another Dianna Wynne Jones story. I'll summarize before the next chapter.
